What does the notion of payment gateway integration mean?

A payment gateway is a software system financial services payment processing. It encrypts the processed data and assist the clients to authorize correctly without issues. The payment gateway serves as a link between the buyer and the seller. Money is accepted via payment systems.

Generally, these are different systems, but large companies combine two services into one, for example, PayPal. It is a payment system which at the same time provides secure data transfer.

What are payment gateway operational principles?

A payment gateway is an element in a complex process called online payment. It is responsible for the reliability and security of data transmission between the buyer and the seller. All information is encrypted and not available to third parties.

Let's see how the payment gateway operates. We've described the whole process step by step below:

  1. 01
    A customer orders goods or services in the online store and is redirected to the payment page. He or she enters the details of debit cards on the payment system website. The payment gateway transmits the received information to the acquiring bank.
  2. 02
    The bank sends an authorization request to some international system through which the payment is made (Mastercard, Visa). It confirms the payment by sending an authorization code through the acquiring bank.
  3. 03
    At this moment, the customer gets a message sent by the bank. He or she enters the numbers on the website and receives confirmation of the successful operation.

The process itself takes a few seconds, but delays are possible. They occur due to numerous simultaneous requests that come via the payment gateway.
