**Fast Pay** is a direct payment method that enables the collection of recurring charges without requiring OTP verification from customers, making the payment process quick and seamless.&#x20;

The system will immediately process the transaction by calling API Pay with the card information or token without redirect customers to an authentication page (OTP challenge page).

With the **Fast Pay API**, merchant can integrate this method into their system to handle recurring transactions, such as membership fees or subscription services, automatically and securely.
