Stripe Forms

Integrate your WordPress forms with Stripe to process your one-time and recurring payments. Stripe forms enhance the user experience by allowing users to stay on your site while securely making a payment.

As of Formidable Stripe version 3.0, the add-on has been updated to accept payments with Link by Stripe. Learn more on how to set up Stripe Link.

Download and install

1. If you haven't already done so, install and activate Formidable Forms.
2. (Optional) In your WordPress admin, go to Formidable → Add-Ons and click the Install button for the WordPress Stripe plugin.
3. Once the plugin has been activated, go to your WordPress Dashboard and look for the Formidable menu.
Note: If you use Stripe with Formidable Forms Lite, Expired, Basic, or Plus license, a fee of 3% will be charged in addition to the Stripe fees. Stripe handles all of this, and no additional steps are required from the customer. To avoid paying the extra 3% charge, upgrade to Formidable Forms Business or Elite.

Set up Stripe API integration

Once you have successfully activated Formidable Forms, you need to connect it with your Stripe account to start accepting payments. To do this, follow the steps below.

1. Go to the Formidable → Global settings → Stripe tab, and click the Connect to Stripe button. Keep in mind that this will need to be done once for testing purposes and once for when the system goes live.
   
   Processing one-time payments option is a premium feature.
2. To authorize the connection between your forms and Stripe, you will be redirected to connect.stripe.com, where you can log in and select your Stripe account.
   
   If you are not the account owner and only have developer access, you can use this code snippet to use the API keys for integration. Support for API keys is a premium feature.
3. After completing the required steps in the Stripe wizard, you will automatically be redirected back to your site.
4. To confirm a successful connection, look for a green checkmark with the text Connected next to the Connection Status.
   
5. Now you are ready to start collecting secure payments. All the webhooks are covered, and need no additional setup.

Set up a Stripe form to collect payments

Once you have the Stripe plugin activated and have connected your Stripe account, you can set up a form to take Stripe payments. Follow the directions below to collect Stripe payments with a Formidable form.

1. Go into edit the form and add a Payment field to start processing payments in Stripe.
   .
2. Go to your form Settings → Actions & Notifications, and click Collect a Payment.
   
3. Give your Payment action an Action Name for easy reference. This name will only be seen on the back-end.
   
4. Give your Payment action a Description to attach to the payment. This information will be sent to Stripe along with the payment. You can either type in a description, or use a field from your form to set the description dynamically. If you would like to use a field for the description, click the icon in the Description box and then select your field in the modal box. This will insert a value like [3130] for your Description setting.
5. Set the Amount for the payment. You can either type in an amount, or use a field from your form to calculate the amount. If you would like to use a field for the amount, click the icon in the amount box and then click your field in the modal box. This will insert a value like [3138] for your Amount setting.
   It may be helpful to use field calculations to calculate a total in your form. Note: If you are using a field that uses separate values in the Amount field, insert [x show=value] instead of [x], where x is the field ID.
6. Your Payment Type can be one-time or recurring. You can add multiple actions to your form if you would like both one-time and recurring payments. If you would like to allow either a one-time payment or recurring subscription, be sure to add conditional logic to both actions so they will only trigger at the times you would like. If you have chosen a recurring payment type, you will see the following options:
   
7. Would you like to Capture the Payment later? You can authorize the payment now, and manually collect it later. Or finalize and collect the payment when the entry is submitted. Capturing a payment later is a premium feature.
8. Set your preferred currency for Stripe. By default, this will be set to the Global currency.
9. Click the toggle to enable Stripe link and additional payment methods. Learn more on the different Stripe payment gateways.
10. The Customer Information fields can be associated with field values in your form.
    
    If you would like to pass a custom address to Stripe, you will need to add an Address field to your form.
11. You can also change field values automatically when a payment is completed, fails, or is refunded. Anything you set here will be also be triggered with every payment in a subscription. After Payment settings are a premium feature.
    
    For example, if you are creating posts, and would only like the post published when it is paid, use the After Payment settings. When the Payment is Completed, set your post status field to "publish". When Failed, set it back to "draft."
12. After saving the Collect a Payment form action, a Payment method field is added automatically on your form. This field is required. Do not remove it or your payments will not be sent to Stripe for processing.
    
Notes:

• With Strong Customer Authentication (SCA) implementation, the payment field is not visible when editing an entry.
• When the form is submitted, an entry is created. If the payment fails, the entry is deleted immediately after.
• If you have set up your emails to trigger when an entry is created, it will still be sent even if the payment fails. If you only want to send the emails for completed payments, change the trigger to Successful payment.

Trigger Actions after payment

There are several actions that can be triggered after a payment is complete or fails. Email notifications, Twilio (text messages), and MailChimp actions are currently setup to work this way. In each of these actions, you'll find options in the "Trigger this action after ____" setting. If you would like an email to be sent after the payment is complete, uncheck "Create" and check "Successful Payment."

When a one-time payment fails initially, only the entry created trigger is activated. The "Failed Payment" event will not trigger in this case, only for a recurring payment that fails.

With recurring payments, each payment will trigger one of these actions ("Successful Payment" or "Failed Payment"). The "Failed Payment" event occurs when a payment that is part of a recurring subscription fails.

Run a test payment

It is often helpful to run a test payment to ensure that your form and Stripe function well. By enabling test mode, you can simulate transactions without impacting actual payments. Follow the steps below to run a test payment.

1. Go to the Formidable → Global settings → Stripe tab.
2. Select the option to Use the Stripe test mode. Make sure you have connected to your Stripe account for the Test connection. Hit Update.
   
3. Open the page where your Stripe form is published.
4. Submit a test entry. Use 4242424242424242 for the credit card number, any three digits for the CVC, and any future date. Enter at least 50 cents for the amount.
5. To access the Payments page, navigate to Formidable → Payments. Once there, you will see a column labeled Mode, which shows test payments if it has a value of Test.
   
6. That's it! The form should be submitted normally if it is configured well and there are no errors.

If you want to test a variety of situations, see Stripe's testing documentation.

Save payment status in a field

If you would like to save the status of a payment in a field in your form, follow the instructions below.

1. Go into a form that has a Stripe action included.
2. Add a hidden field and Name it 'Payment status'.
3. Go into your form's Settings → Actions & Notifications and open the Stripe form action.
4. Scroll down to the After Payment section. Click the Add button.
   
5. In the 'Payment Status' column, select Completed. In the 'Field' column, select your 'Payment status' field. In the Value column, select Completed. You can do the same for the Refunded and Canceled payment status.
   
6. Hit Update. When a form payment is successfully completed, the payment status field will switch to Completed' to reflect the status of the Stripe payment. If the payment status is not updating properly, please make sure that your API keys are set up and saved accurately.

Add sales tax to total

You can calculate sales tax by following our guide to calculating sales tax. Then you can add it to the total amount collected in your Stripe payment action.

Conditionally collect payments

If you would like to set up different payment options in your form using Stripe, you'll need Conditional Logic. Suppose you have three payment plans in your form: Basic, Pro, and Enterprise.

1. In your form, add a 'Dropdown', 'Radio', or 'Checkboxes' field called 'Payment Plan'. For this example, you would add the options: 'Basic', 'Pro', and 'Enterprise'. When your users fill out the form, they will select the payment plan that they would like to avail.
2. Go to your form Settings → Actions & Notifications. Click Collect a Payment.
   
3. Rename the label to 'Basic Plan' and select your preferred payment type, if it is a one-time payment or recurring.
   
4. Select Add Conditional Logic. In this example, you would set 'Payment Plan' is equal to 'Basic'.
   
5. Click the Update button to save the form action.
6. Now, users who selected the 'Basic' payment plan will only be charged for the amount relevant to their chosen payment option.
7. Repeat steps 2-5 to create the form actions for the other payment plans.
8. To be sure that the one-time payment is processed, go to the Formidable → Global settings → Stripe tab, and select After entry is created.
   
9. Click the Update button to save the Stripe settings.

Need to conditionally collect payments through Stripe and PayPal in the same form? See how to add optional online payment processing to WordPress Forms.

Set up a recurring payment

If you would like to set up a Stripe form action to take recurring payments, follow the steps below:

1. Set up your WordPress form to take Stripe payments.
2. Under Payment type select 'Recurring'.
3. In the Repeat Every section, select how often the payment will recur.
   
4. You may include a trial period before the actual subscription begins. If you would like to include a trial period, select how long the 'Trial Period' will be.
   
5. Click Update. Now when a user submits the form, Stripe will automatically bill the user at intervals determined by your 'Repeat Every' setting.

Set up multiple types of payment

With Stripe, any number of payment options can be triggered on single form submission. Here's an example of how you can allow multiple payments such as one-time (non-recurring) payment, payment with a trial, and recurring payment. All of these form actions should trigger upon form submission.

1. Go to Settings → Actions & Notifications. Click Collect a Payment to add a Stripe form action.
   
2. In the Action Name box, insert 'Collect a Payment'.
3. In the Amount box, type in the amount of the non-recurring payment or use a field from your form to calculate the amount.
   
4. In the Payment Type, select 'One-time Payment'.
5. In the Actions & Notifications, add another Collect a Payment form action.
   
6. In the Action Name box, insert 'Collect a Payment with trial'.
7. In the Amount box, type in the amount of the recurring payment or use a field from your form to calculate the amount.
   
8. In the Payment Type, select 'Recurring'.
9. In the Repeat Every section, select how often the recurring payment will take place. In the Trial Period section, select how long the 'Trial Period' will take place.
   
10. In the Actions & Notifications, add another Collect a Payment form action.
    
11. In the Action Name box, insert 'Collect a Recurring Payment'.
12. In the Amount box, type in the amount of the recurring payment or use a field from your form to calculate the amount.
    
13. In the Payment Type, select 'Recurring'.
14. In the Repeat Every section, select how often the recurring payment will take place.
    
15. Click Update. When the user submits the form, all form actions will be triggered for each type of payment.

Conditionally allow credit card payments

To conditionally allow credit card payments in your Stripe form, you will need Conditional Logic. Suppose you have two payment plans in your form: Pay via credit card and pay in person.

1. In your form, add a dropdown or radio field called Choose Payment. For this example, you would add the options: Pay via credit card and Pay in person.
   
2. In your Payment field, add conditional logic that shows this field if the dropdown or radio field equals Pay via credit card.
   
3. Go to your form Settings → Actions & Notifications. Click Collect a Payment.
   
4. Rename the label to Credit Card Payment. Add in the amount and select your preferred payment type if it is a one-time payment or recurring.
   
5. Add conditional logic to the Stripe form action. Set it up to trigger when the dropdown or radio field equals Pay via Credit Card.
   
6. Click the Update button to save the form action.

When your users fill out the form, they can select which payment plan they would like to use. If they choose Pay via credit card, the users will only be charged for the amount configured in the Stripe form action.

How to find the payment action ID

To find the payment action ID, go to your form Settings → Actions & Notifications → Collect a Payment and look for the payment action ID at the bottom right corner.

Set up Stripe Link

Link by Stripe is a secure and fast way to collect payments with the one-click checkout process. It allows users to store their encrypted information easily for future transactions. Learn more about Stripe Link.

1. To get started, go to your Stripe Dashboard → Settings → Payment Methods and select your site from the dropdown on the upper left corner. Scroll down to the Wallets section and click the Turn on button for the Link payment method.
   
2. If you haven’t yet, set up your Stripe form to collect payments.
3. In the Stripe form action, switch the toggle on for Use previously saved card with Stripe link to enable it.
   
4. Upon checkout, user accounts are authenticated by Stripe link using their email address.
   • Collect email at payment. If you have not added an email field in your Stripe form action, the Stripe Link will automatically insert an email field on the payment form, right above the payment field.
     
   • Collect email before payment. If you have added an email field in your Stripe form action, it will trigger the Link authentication flow when the user enters their email address.
     
5. When an existing user completes the payment form again, Stripe Link will verify their identity by prompting a one-time code.
   

Testing Stripe Link

You can use any valid email and any code during testing, except for a few codes that trigger errors. Note that the verification code will not actually get sent to your phone during test mode.

• Error 000001: Code invalid
• Error 000002: Code expired
• Error 000003: Max attempts exceeded

Not all 3D secure credit card numbers work with Stripe link for testing. The number 4000000000003220 does work and is intended for testing Stripe link with 3D secure.

Styling Stripe Link

The elements will use your form styling automatically. If a Stripe link input has not yet been validated, the submit button will be disabled. When it is disabled, it will appear at 0.5 (half) opacity/semi-transparent.

Other considerations

• Link by Stripe is fully launched in the US and several other countries. Learn more on Stripe's Website - Country Availability.
• Stripe link actions are not compatible with other Stripe actions. It's advised not to have more than one payment action when using link.
• In terms of browser compatibility, Stripe elements don't support Internet Explorer.

Stripe payment methods

Easily collect one-time and recurring Stripe payments in your form via credit card, US Bank accounts, Alipay, iDEAL, Klarna, ACH Direct Debit, and more. Click here for more information about the available Stripe payment methods.

Processing payments

There is a processing intent status that some payment methods will use, including ACH Direct Debit (US Bank Account).

When a form is submitted with a processing payment status, it will include a Stripe processing message right after the submit message.

The additional message can be customized in the Formidable → Global Settings → Message Defaults.

Set up a Stripe form to send emails

After setting up a form to collect Stripe payments, you can select the Successful Payment trigger to send an email once the payment has been completed. Emails will only be sent once Stripe confirms that the payment has been successfully processed.

Here are some of the action types that could be triggered after payment:

• Failed Payment. Set an automated email notification in case of a failed payment.
• Processing Payment. Set an automated email notification when payment is submitted to Stripe but is not completed.
• Canceled Subscription. Set an automated email notification when a recurring payment is canceled.
• Canceled Subscription and Expired. Set an automated email notification when a recurring payment has been canceled and expired.
• Refunded Payment. Set an automated email notification on a refund.

Resend emails on complete payment

If you have set up an email to trigger after collecting a Stripe form payment, you can resend an email by following the steps below:

1. Add a payment status field in your form if you don't have one already.
2. Go into the form's Stripe action. In the After payment section, set the value to Paid when the payment status is Completed. 
   
3. Add another email action to your form, set the trigger to Entry is created.
4. Add conditional logic to this email action to fire only when the Payment status field is equal to Paid.
   
5. On your form Entries page, click the entry that you want to resend the email.
6. In the Entry Actions section (right sidebar), click the Resend Emails link to resend the email.
   

Note: This process will work if you have selected After entry is created in your Formidable → Global settings → Stripe page.

Customize the subscription renewal email

To set this up, you can use the inline conditional statements. In this case, if the entry was created more than 14 days ago, the email content can be different.

[if created_at less_than='-7 days']Thanks for your renewal! Your next payment will be in x days.[/if created_at]

[if created_at greater_than='-7 days']Thanks for your initial payment! Your first renewal will trigger in x days.[/if created_at]

Replace 7 with your renewal period.

Set up Authorize and Capture

Stripe has a two-step payment process which allows you to authorize a payment then capture it later. One of the benefits of using this feature is that you can capture the cardholder's payment only after an order or item is ready. This can help in reducing processing fees if there is a chargeback or refund. To get started, follow the steps below:

1. Open the form action settings to create a Stripe payment. Change Capture Payment to Later (collect manually).
2. Go to Formidable → Payments. When a payment is authorized but not captured, the status will be displayed as Authorized.
   
3. Select the payment to manually capture and click Capture now.
   
4. If the payment was successfully captured, the payment status will change to Completed. If the payment is not captured within 7 days, the authorization will expire and the funds will be released

Process refunds

Once you have received a payment, refunding said amount can be quickly done with the Stripe add-on.

1. To do this, navigate to Formidable → Payments. Hover over the Receipt ID for the payment you want to refund and click on View.
   
2. Inside this page, you can see several bits of information, but what we are looking for is located on the top right corner of your screen, the 'Payment Details' widget.
   
3. Click on Refund and click Yes in the confirmation box that shows up. If everything works as expected, the word Refunded should appear where the Refund button used to be.
   

Export list of payments

If you would like a compiled list of all the payments made in your Stripe form, you can export the entries as a CSV file. This will include the payment details and status.

To get started, navigate to the Formidable → Entries page and select the form where the Stripe payments were made. Then click the Download CSV button above the entries table to export the payment details via CSV.

Show a list of subscriptions

As an admin, you can see all the subscriptions on the Formidable → Payments → Subscriptions page.

Each subscription can be canceled from here as well.

Show subscriptions for current user

If you would like to show your users a list of their subscriptions, along with cancellation links, insert [frm-subscriptions] on a page. If a user is logged in, they will see their subscriptions listed here.

Conditionally show active subscriptions

If you would like to display the active subscriptions for the current user but conditionally show the payment form when there is none, you can set this up by following the instructions below.

1. In the form builder, add a hidden field called Payment Status and save the payment status in the field. Make sure that you have added a field for the Completed payment status.
2. Create a single entry View of the same subscription form.
3. Set up the View filter such as:
   • User ID is equal to current_user.
   • Payment Status is equal to completed.

   

4. In the Listing Page Content box, insert the [frm-subscriptions] shortcode to show your users a list of their subscriptions.
   
5. In the No Entries message box, insert your Payment form shortcode:
   
6. Click Update and publish the View on a page.

Get receipt ID

If you would like to get the receipt ID for a specific entry, you may use this shortcode:

[frm-receipt-id entry="[id]"]

This shortcode may be placed in a View, email message, success message, or even an API action that fires after a payment is complete.

Publish a post on complete payment

If you would like to publish a post after collecting a Stripe form payment, follow the steps below.

1. Set up your form to take a Stripe payment.
2. Add a Create posts action.
3. Add a post status field to your form, if you don't have one already.
4. Select 'Draft' as the default value in your new 'Status' field.
   
   If you do not want the user to have access to changing the status of this field, you can set the field to Read Only. You can also hide the whole field from the user by changing the Visibility to 'Administrator'.
5. Click Update.
6. Go into the form's Stripe action. In the After Payment section, set the dropdown in the Payment Status column to 'Completed', set the dropdown in the Field column to your 'Status' field, and type 'publish' in the Value column.
   
7. Click Update and Publish your form on a page. Now when a user submits the form with their payment information received, the post will be published.

Troubleshooting

The Stripe Token is missing

If you see this error message, check each of the following:

1. Do you have a payment field in your form? If not, this is required in order for a payment to process.
2. Is your API key correct? Please review the steps above to make sure your API keys are setup and saved accurately.
3. Do you have more than one payment form on the same page? This is a current limitation of the Stripe add-on that we plan to improve in the future.
4. Are Formidable Forms and Formidable Forms Pro up to date? If not, please update.
5. Do you have another plugin installed that uses Stripe? If so, try deactivating it to check for a conflict.
6. Do you have the Formidable Authorize.net plugin installed? If so, you'll need to choose between the two. They are currently not designed to work together.

If you continue getting this message, please create a new ticket in the help desk.

No such plan

The Stripe form settings automatically create a plan in Stripe. However, if the Stripe account is changed, the plan will not exist in the new account. If you submit a payment form and see the 'No such plan' message, return to the Stripe payment settings for this form, and save the settings again. This will trigger the plan to be created in Stripe again. It may help to make a small change in these settings to ensure the plugin knows to create the plan.

No such customer

When a logged in user submits a payment, a customer is created for that user in Stripe. The customer ID is linked to the logged in user. If the Stripe account is changed, or the customer account deleted in Stripe, a logged in user who has previously submitted a payment may see the message "No such customer" when a payment form is submitted. When this happens the customer ID is unlinked from the user, and the next try from this user should be successful. This message will not appear for logged out users or for those submitting the first payment. To avoid this issue, do not delete customers in Stripe.

If this error continues, the customer id assigned to the user can be manually deleted in PHPMyAdmin or with a line of code.

$user_id = 1; // Change the user id to the user getting errors.
delete_user_meta( $user_id, '_frmstrp_customer_id' );
delete_user_meta( $user_id, '_frmstrp_customer_id_test' );

Incomplete payments

When a form is loaded, an incomplete payment is created in Stripe. As the form is filled out, the value of the payment is updated.

If you would like to disable these incomplete payments in Stripe for $1 (or another currency), go to Formidable → Global Settings → Stripe. Set the option to Process One-time Payments to After entry is created.

Payment Intent status: requires_payment_method

If you are seeing this error in the Stripe logs, then it is possible that the automatically generated "Payment Method" field has been deleted or otherwise modified. This field is hidden, but required for Stripe to process the payment. If you don't see the field in your form, delete the payment field and the Stripe form action, and then re-create them. If the field is present, make sure there is no conditional logic set on this field.

The provided PaymentMethod was previously used

If you are seeing an error message that looks similar to this: "The provided PaymentMethod was previously used with a PaymentIntent without Customer attachment", first make sure that you are running the most current version of the Stripe add-on. If you are and continue to see this message, it's possible that the Payment Method field has become unlinked from the Stripe form action. Try deleting the Payment Method field from your form, along with the Stripe form action(s), and recreate the Stripe form action(s).

Please specify an amount for the payment

If you are seeing this error message when attempting to submit your payment form, then there is likely an issue with the Amount set in the Stripe form action. Please check the following:

• There are only numbers in the Amount field in the Stripe form action—no commas, currency symbols, or text.
• If using a field to calculate the total, make sure the correct field shortcode is in the Amount field in the Stripe form action, and the calculation is correct and contains no text.
• If the above steps do not resolve the issue, try deleting the Payment Method field from your form and the Stripe form action, and recreate the Stripe form action.

Logging for other errors

A log file is stored inside of the Stripe plugin that keeps a list of the most recent errors. If you run into an error related to the payments and are not sure where to start, a log message would be helpful. The log can be located in wp-content/plugins/formidable-stripe/formidable-payments/log/results.log. The most recent messages are at the bottom of the log.

In addition to the log stored in Formidable, Stripe has a separate log. It may be useful to compare the two and see if additional errors are appearing in your Stripe account log as well. You can find it in your Stripe dashboard under Developers → Logs.

No payments created

If no payments are showing up under your Formidable → Payments page, it's possible that your database has not created a Payments table or is not properly updating. On some servers, the database user doesn't have permissions to ALTER database tables. To grant and revoke rights to database tables using phpMyAdmin, follow the instructions below:

1. Navigate to the Privileges tab which has a list of your users.
2. Click the Edit Privileges link.
3. Select your database.
4. In the Database-specific privileges, select the wp_frm_payments table.
5. In the Table-specific privileges, you can define the operations in detail.
6. Manually make adjustments to the table to match the structure in our database schema.

Note: If you are using the PayPal add-on at the same time, leave the Completed column as is.

Cannot set id on this object

If you see the error message Cannot set id on this object. HINT: you can't set: id, check each of the following:

1. Do you see anything related to this error in the Stripe logs?
2. Do you have another plugin installed that uses Stripe? Try deactivating it to check for a conflict.

If you continue getting this message, please create a new ticket in the help desk.

The account id does not match its signature

If you see this error message, it means that no account ID is sent to our Stripe connect service. The data that is being passed to us isn't what we're expecting it to be.

You might want to check if your Stripe API integration has been disconnected or if the account password is wrong. If you continue to see this message, check for plugin/theme conflicts.

The payment method type link is invalid

If you see this message along with a 400 error in the Stripe dashboard, you have not enabled Link first in the Stripe dashboard. Please ensure that the provided type is activated in your dashboard.

Stripe connections are not working

If you click the Connect to Stripe button and it never reaches the initial Stripe setup page, you might be getting blocked by a security service on their server. If you see an error message cURL error 28: Connection timeout, please check the following:

• Your web host may be blocking communication with formidableforms.com and causing the Stripe connections to stop working. how to whitelist our IP.
• The cURL is not enabled on your server. If you need help checking this, contact your host to find out.
• If that does not eliminate the error message, you may be behind a corporate firewall preventing communication with formidableforms.com. Please get in touch with us through the help desk for assistance.

Missing payments

If the Stripe payment is not reflected even after submitting the form, you might have added conditional logic to the Payment method field. It can affect the Stripe form action, resulting in the form being submitted without processing any payments or displaying errors. To resolve this issue, try to delete the conditional logic from your Payment method field.

If you plan to collect payments only when a specific field option is selected, you can add conditional logic to the Stripe form action. Stripe can trigger any payment option on a single form submission. It will ensure that the payment is triggered only when required. Learn more about conditionally allowing payments.

Additional Customizations

Change the user role

You may want to change the role back if a payment fails or is refunded. Use the frm_payment_status_complete hook if you want to change the user role when the payment is completed. With a recurring payment, this hook will be fired each time a payment is completed.

Similar hooks are fired each time the status on payment changes. These hooks work exactly the same way but simply fire at different times.

• frm_payment_status_complete
• frm_payment_status_refunded
• frm_payment_status_failed
• frm_payment_status_canceled

Trigger an action based on payment amount

If you want to trigger an action in another form (or the same form) when a payment is more than a certain amount, use the following example:

add_action( 'frm_payment_status_complete', 'frm_trigger_action_on_payment' );
function frm_trigger_action_on_payment( $atts ) {
  $payment_amount = $atts['payment']->amount;

  if( $payment_amount < 100.00 ) { // Change 100.00 to the payment amount above which you want to trigger the action
	return;
  }
  
  $entry_id = isset( $atts['entry'] ) ? $atts['entry'] : $atts['payment']->item_id;
  $entry = FrmEntry::getOne( $entry_id, true );
  $form = FrmForm::getOne( $entry->form_id );
  FrmFormActionsController::trigger_actions('update', $form, $entry, 'email');
}

As is, the above example will trigger all Email actions set to trigger on update, in the same form. If you want to trigger an action in a different form, change $entry_id to the entry ID of an entry in another form.

Trigger an action on complete payment

Use the frm_payment_status_complete hook if you want to target a specific payment action ID and send an email on complete payment.

Save receipt ID in a field

If you want to trigger saving the receipt ID into a field on complete payment, use the following example:

add_action( 'frm_payment_status_complete', 'frm_trigger_receipt_on_payment' );
function frm_trigger_receipt_on_payment( $atts ) {
$receipt_id = $atts['payment']->receipt_id;
$entry_id= $atts['payment']->item_id;
	if(!empty($receipt_id)){
		FrmEntryMeta::add_entry_meta( $entry_id, 1819, "", $receipt_id); //change 1819 to the ID of the field in which you want to store the entry ID
	}
}

Use the Stripe receipt

By default, an email form action can be used to send a receipt. In this case, the email would be set to trigger after successful payment. But this example will allow you to use the Stripe receipts.

add_filter( 'frm_strp_new_charge', 'set_stripe_to_trigger_receipt', 10, 2 );
function set_stripe_to_trigger_receipt( $new_charge, $atts ) {
  if ( $atts['action']->ID == 30 ) { // change 30 to your payment form action ID
    $email_field_id = 25; // change 25 to your email field id
    $new_charge['receipt_email'] = $atts['entry']->metas[ $email_field_id ];
  }
  return $new_charge;
}

Note: This will only work for live payments. Read more about using Stripe receipts.

Get customer ID

You can find the Stripe customer ID in the user meta called _frmstrp_customer_id or _frmstrp_customer_id_test. To get the customer ID, use this line of code:

get_user_meta( get_current_user_id(), ' _frmstrp_customer_id' )

Use the Stripe API Key integration

With version 2.04 and later, you will be redirected to connect.stripe.com to integrate your Stripe account. If you are not the account owner and only have developer access, you can use the following code snippet to use the API keys for integration.

add_action( 'plugins_loaded', function() {
	$options = get_option( 'frm_strp_options' );
	if ( false === $options ) {
		$options = new stdClass();
	}

	$options->test_secret  = 'sk_TEST_SECRET';
	$options->test_publish = 'pk_TEST_PUBLISH';
	$options->live_secret  = 'sk_LIVE_SECRET';
	$options->live_publish = 'pk_LIVE_PUBLISH';

	update_option( 'frm_strp_options', $options );
});

When adding the endpoint, select the latest API version and enable ONLY the following events:

• charge.captured
• charge.refunded
• customer.deleted
• customer.subscription.deleted
• customer.subscription.updated
• invoice.payment_failed
• invoice.payment_succeeded
• payment_intent.payment_failed
• payment_intent.succeeded

Customize the subscription cancel link

If you show subscriptions for the current user, you can customize the cancellation link displayed with the subscription by following the example below.

add_filter('frm_pay_stripe_cancel_link', 'customize_stripe_subscription_cancel_link');
	function customize_stripe_subscription_cancel_link( $link, $subscription ) {
		$link = str_replace( '>Cancel<', '>' . 'Cancel Subscripion ID ' . $subscription->id . '<', $link );
		return $link;
	},
	10,
	2
);

Update credit card details

The Stripe customer portal lets users manage their subscriptions and billing details through a Stripe-hosted page. With the no-code Stripe customer portal link, you can configure the following settings:

• Payment Method: Add or delete credit card payments.
• Subscriptions: Upgrade, downgrade, or cancel a subscription.
• Billing information: View and update billing information, such as name, address, and phone number. Note: Users can’t update their email address if they are using the no-code customer portal link.
• Invoice: View the invoice history.

If you want your users to update their payment method, such as credit cards, you can use the Stripe customer portal no-code link to set this up. Follow the instructions to get started.

1. Go to Stripe → Settings → Billing → Customer Portal.
   
2. Select your configuration options for payment methods.
3. In the Customer Portal link section, click the Activate link button and copy the customer portal link.
   
4. Go back to your site. Create a new page, add a WordPress button block, and paste the customer portal link. (Optional) To show the subscriptions for the current user, you can insert the [frm-subscriptions] shortcode on the same page.
   
   You could also use HTML to create the link.

   <a href="https://billing.stripe.com/p/login/test_xxxx">Update payment method</a>

5. When the user clicks the link, it will redirect them to the Stripe Customer Portal page, where they can add or delete their payment method.
   
Note: If you plan to test the customer portal before going live, it must be configured in the Stripe Dashboard for both Live and Test modes.

Are there any fees associated with using Stripe in my forms?

Yes. A 3% transaction fee will be charged for each payment processed if you use Formidable Forms Lite or your license does not use the Stripe add-on. It is in addition to the Stripe fees they may charge depending on how you use their platform. Please check out their pricing tiers for a breakdown of Stripe's pricing. The extra 3% charge is not included on Business or Elite plans. Upgrade to the plan that eliminates this fee.

How can I enable the additional payment methods?

The Stripe link and additional payment methods are enabled by default. Learn more about the different Stripe payment gateways.

Why is the Connect to Stripe button not working?

Only owners or administrators are granted permission to connect an account using Stripe Connect. If you need help completing the process, please verify your Stripe user role to ensure it meets the requirements. If you continue having problems connecting to Stripe, follow these troubleshooting steps.

Is my payment information stored in the form?

Rest assured that sensitive credit card information entered on your website is secure. Instead of sending the credit card information to your server, it will be hosted in an iframe by Stripe. Stripe will handle all the compliance measures, and your users' credit card details are never at risk on your server.

Are the Stripe keys stored in Formidable Forms?

With Stripe Connect as the default integration, users do not need to store their API key. We use generated passwords that only work when making requests through our API. It is more secure as it eliminates the need to manually handle or store your sensitive API Keys in plain text.
