What is a Payment Gateway?
A payment gateway is a technology used by merchants to accept debit or credit card payments from customers. It acts as the bridge between your website and the bank that processes the payment. Payment gateways ensure that customer data is encrypted and securely transmitted to prevent fraud and unauthorized access.
How Does a Payment Gateway Work?
A payment gateway facilitates the online transaction process by authorizing payments and transferring funds between the customer and the merchant. Here’s how it works:
- Customer Places an Order: The customer selects a product or service and proceeds to checkout.
- Payment Details Entered: The customer enters their payment details on the website’s payment page.
- Transaction Encryption: The payment gateway encrypts the customer’s payment information to ensure secure transmission.
- Authorization Request: The payment gateway sends the encrypted payment information to the bank or payment processor for authorization.
- Transaction Approved or Declined: The bank or payment processor checks the details and approves or declines the transaction.
- Confirmation: The payment gateway sends a confirmation back to the merchant’s website, and the customer receives a notification of a successful payment.
Types of Payment Gateways
- Hosted Payment Gateways
- Customers are redirected to a third-party payment page to complete the transaction.
- Examples: PayPal, Stripe.
- Self-Hosted Payment Gateways
- Payment details are collected on the merchant’s website and then sent to the payment gateway for processing.
- Examples: Authorize.Net, Adyen.
- API Payment Gateways
- Payment processing is handled via APIs, allowing more customization and integration options.
- Examples: Braintree, Razorpay.
