What is Payment Gateway API?

Payment Gateway API, or Application Programming Interface, serves as the bridge between a merchant’s website or application and the payment processing network. It enables developers to integrate payment gateway services seamlessly into their platforms. By leveraging Payment Gateway APIs, businesses can securely accept a variety of payment methods, including credit cards, debit cards, and digital wallets, without the need for customers to leave the website or application.

 

How does Payment Gateway API Work?

  1. Payment Request: When a customer pays, the platform sends a request to the API.
  2. Secure Transmission: The API sends payment details securely to the processor.
  3. Authorization: The processor verifies the transaction with the bank.
  4. Transaction Processing: If approved, the processor deducts the payment.
  5. Response Handling: It sends a response to the API with the transaction status.
  6. Customer Notification: The API informs the platform of the status.
  7. Transaction Settlement: Finally, the processor transfers funds to the merchant.
