The Grant API is currently in a limited release. Contact us to determine whether it's right for your needs and to request access to the API.

The Grant API allows you to give another Braintree merchant controlled access to one of your customer's payment methods.

When you revoke a grant, we delete the version of the payment method from the receiving merchant's Vault.

PHP
$gateway->paymentMethod()->revoke(
  'the_token'
);
Arguments
sharedPaymentMethodToken required, string

The alphanumeric value that references a specific payment method stored in your Vault.
