This article is for you if you want to build a payment gateway website. We will look at the cost, advantages, use cases, and possibilities of creating a payment gateway in this post.
What Is Payment Gateway And How Does It Function?
The worldwide payment gateway industry is expected to rise at a compound yearly growth rate of 18.4% from US$32.72 billion in 2024 to over US$44.68 billion in 2025. Companies use a system known as a payment gateway to accept debit and credit card payments. It is a go-between for a company’s website and its acquirer, making it easier for payment information to be transferred securely. When consumers input their payment information online, the payment gateway encrypts the information before sending it to the payment processor.
The payment processor then works with the issuing banks and card networks to determine whether to approve or reject the transaction based on the user’s available money and account status. The payment procedure is then finalized when the payment gateway returns the transaction status to the company website. Below is a detailed breakdown of how payment gateways function:
- Collects essential payment information like credit or debit card details, customer authentication details, and billing and shipping addresses.
- Encrypts sensitive customer information using SSL protocols to protect data from fraud.
- Securely transmits encrypted customer data to the acquiring bank or payment processor.
- Forwards transaction data to the issuing bank for verification and approval or decline.
- Sends approval or decline status back to the payment gateway.
- Relays this message to the merchant and customer.
- If approved, the acquiring bank settles the funds with the issuing bank.
- The merchant receives payment within a specified timeframe.
- Both the customer and merchant receive confirmation of the completed transaction.
