Using Gravity Forms ‘gform_stripe_enable_rate_limits’ PHP filter

by

The gform_stripe_enable_rate_limits filter enables or disables error rate limiting when processing a Stripe feed in Gravity Forms. Error rate limiting is enabled by default, blocking any IP that reaches 5 errors for an hour.

⚠️ This filter should only be used while testing your forms. Do not use this filter to disable error rate limiting with the Stripe add-on set to “Live” mode on the Forms > Settings > Stripe page. 

Error rate limiting prevents your forms with the Stripe add-on from being used for fraudulent card testing. Disabling it in a production environment may lead to processing transactions from fraudulent individuals testing stolen credit cards, resulting in potential card disputes.

Usage

add_filter('gform_stripe_enable_rate_limits', 'your_function_name');

Parameters

  • $has_error (bool): Indicates whether error rate limiting is enabled. Defaults to false (error rate limiting enabled).
  • $form_id (int): The ID of the form being submitted.
