What is a payment gateway?

A payment gateway is a service that takes a payment from a customer through a method like UPI, confirms that the money was received, and tells the merchant's system the result so the order can be fulfilled.

The steps

  • Your site creates an order with the gateway.
  • The customer pays on the gateway's checkout.
  • The gateway confirms the payment.
  • The gateway notifies your server with a signed callback.
  • Funds are added to your balance for payout.

Gateway vs. payment link

A payment link uses the same gateway, but instead of an API integration you share a URL with the customer.
