How Payment Gateway API Integration Works

Payment Gateway API Integration securely connects your platform to a payment gateway, allowing real-time processing of online payments. It collects payment details, verifies transactions with banks, and returns approval or decline instantly—enabling seamless, safe checkout without redirecting customers to external sites.

1. Customer Initiates Payment

The user selects products or services and proceeds to checkout on your website or app.

2. Payment Details Collected

Your platform collects the customer’s payment information securely (card, UPI, wallet, etc.).

3. API Sends Data to Gateway

The payment gateway API securely transmits this payment data to the payment processor or bank.

4. Authorization & Verification

The payment processor verifies the details, checks for fraud, and confirms if funds are available.

5. Transaction Approval or Decline

The gateway sends back a response—approved or declined—to your platform in real-time.

6. Confirmation to Customer

Your system updates the order status and notifies the customer of payment success or failure.

7. Settlement

Approved payments are settled between banks and funds are transferred to your merchant account.
