The gform_stripe_checkout_supported_cards Gravity Forms PHP filter was used to modify the list of supported credit cards for the Stripe Checkout. However, this filter has been removed in Stripe version 3.0.
Usage
add_filter('gform_stripe_checkout_supported_cards', 'customize_supported_cards');
function customize_supported_cards($supported_cards) {
// your custom code here
return $supported_cards;
}
Parameters
$supported_cards(array): An array of supported credit card types.

Important: This filter was removed in Stripe version 3.0. With the new version of Stripe Checkout, the supported cards can no longer be modified.
Examples

function remove_amex_from_supported_cards($supported_cards) {
// Remove 'amex' from the supported cards array
$supported_cards = array_diff($supported_cards, array('amex'));
return $supported_cards;
}
Add Diners Club to the list of supported cards
To add Diners Club to the list of supported cards, you can use the following code:
