How Does a Payment Gateway Work?

The complete payment flow is explained below:

Step 1: Customer Places an Order

The customer selects products and proceeds to checkout on the eCommerce store.

Step 2: Payment Details Are Encrypted

The customer’s browser encrypts sensitive payment information using SSL encryption before sending it to the merchant.

Step 3: Transaction Is Verified

The encrypted payment information is sent to the payment gateway through the merchant account.

The payment gateway forwards the transaction to the payment processor.

The payment processor then sends the request to the respective card network, such as Visa or Mastercard, for verification.

Step 4: Bank Authorizes the Payment

The customer’s bank verifies the transaction and sends an approval or decline response to the payment processor.

Step 5: Payment Is Settled

Once the transaction is approved, the bank transfers the funds through the payment gateway, and the merchant receives the payment.

What is a Payment Processor?

A Payment Processor acts as the bridge between merchants and financial institutions.

It authorizes transactions and ensures merchants receive payments successfully.

Many payment processors also provide additional services such as:

• Card payment processing
• Security solutions
• PCI compliance assistance
• Customer support
• Fraud prevention tools
• Value-added merchant services
