How the Payment Gateway works

Customer starts payment

Your website creates an order and opens FiatPe Checkout for the payable amount.

Customer chooses a method

Checkout presents the payment methods enabled for the order and merchant configuration.

Payment is authenticated

The customer completes the required bank, card, UPI, net-banking, or wallet authentication.

FiatPe returns the result

Checkout returns payment identifiers and a signature while server callbacks provide durable updates.

Merchant verifies and fulfils

Your backend verifies the signature and final status before updating the order exactly once.
