Understanding Payment Gateway Integration
To understand payment gateway integration in simple words, it is a solution that connects your bank account with the merchant’s platform. Basically, it forms a secure tunnel for online buyers and retailers ensuring maximum safety for global purchases.
The payment gateways are very similar to virtual terminals which are equivalent to physical payment terminals. The payment gateway also ensures credit card processing by transferring the essential information between the website and the payment banks and vice-versa.
The best payment gateways for small businesses use security protocols and encryption to securely transfer data without any complications. It sends the data to the appropriate source for approval and then sends the response back to the store. It is during this phase that the payment is accepted and accepted or rejected and declined.
Working Of The Payment Gateway Integration

While you plan to decide which payment gateway to use, it is important to understand its working. A payment gateway is a virtual bridge between the customer and the online store to process and authorize the online payment.
Below is the basic flow for an online payment using the payment gateway:
- As soon as the customers finish the purchase and click on the ‘submit’ button, they are directed to the payment gateway page.
- On that page, the customers choose the desired payment method and enter the required details.
- The entered details are then encrypted, for better security, and transferred to the issuing bank for approval.
- The issuing bank checks and confirms if the buyer has enough funds to make the purchase and sends the approval accordingly.
- The response is received by the merchants. If the response is negative, the transaction is canceled and if the response is positive, the transaction is completed.
- In the next step, the payment is settled between the secure payment gateway and the bank.
- Once this is done, the payment is finally settled between the payment gateway and the merchant.

This may look like a lengthy and time-consuming process but it takes about a few seconds to complete. The process may sometimes be completed within 1-2 minutes because of technical issues.
This entire process is a combination of different transactional types which are,
- Sale or debit
- Authorization
- Capture
- Void
- Refund
- Chargeback, and
- Credit
On the other hand, to ensure high security within the transactions, the eCommerce payment gateway uses technologies like TLS encryption, PCI-DSS compliance, tokenization, and 2-factor authentication.
