The integration in an online store using the Redirect checkout option requires the creation of a Payment Request (Creating a payment request ) and the redirection to the URL obtained in the response of this method, in the parameter checkout_url.
When redirecting to the SimpleFi checkout, it is necessary to include the redirection parameters to the merchant's website once the operation in the checkout is completed. These parameters are:
redirect_url: The URL of the merchant's platform where the user is to be redirected once the payment is successful.
error_url: The URL of the merchant's platform where the user is to be redirected once the payment is not successful.
