FAST PAY BD is a simple and secure payment automation tool designed to use a personal account as a payment gateway, so you can accept payments from your customers through your website. Here you will find a complete overview of how FAST PAY BD works and how to integrate the FAST PAY BD API into your website.
FAST PAY BD Payment Gateway enables merchants to receive money from their customers by temporarily redirecting them to www.fastpaybd.site. The gateway connects multiple payment terminals, including card systems, mobile financial services, and local and international wallets. After the payment is complete, the customer is returned to the merchant's site, and seconds later the merchant receives a notification with the transaction details. This document is intended for technical staff supporting the merchant's website. Working knowledge of HTML forms or cURL is required. You will probably need test accounts, which you can get by contacting fastpaybd.site or which may already have been provided to you.
REST APIs are supported in two environments. Use the Sandbox environment for testing, then move to the live environment for production processing. When testing, generate an order URL with your test credentials to make calls to the Sandbox URIs. When you're ready to go live, use the live credentials assigned to your new signature key to generate a live order URL for the live URIs. Your server must support cURL. For HTML form submission, an HTML POST method URL is also provided after the cURL section.
