An e-commerce site is not complete without a payment gateway. There are many payment gateways in Pakistan one can choose from like 2checkout, stripe, easypay etc., but the most famous online payment gateway in Pakistan is JazzCash payment gateway.
PHP is one of the most common platforms for e-commerce sites. PHP is a secure, fast, and trusted language when it comes to the banking and financial industry. Today various e-commerce websites run on PHP. That’s why I choose PHP for this tutorial.
In this tutorial I will explain the complete registration process for JazzCash merchant account. I will also explain how to integrate JazzCash payment gateway HTTP POST (Page Redirection) mode into any website using php.
What is Payment Gateway
The definition of a payment gateway is the technology that captures and transfers payment data from the customer to the acquiring banks and then transfers the payment acceptance or decline back to the customer.
In other words, the payment gateway works as the middleman between your customer and the merchant, ensuring the transaction is carried out securely and promptly. An online payment gateway can simplify the integration process. As the middleman during the payment processing, the gateway manages the customer’s sensitive card details between the acquiring banks and the merchant.
How Payment Gateway Works
A payment gateway validates the customer’s card details securely, ensures the funds are available and eventually enables merchants to get paid. It acts as an interface between a merchant’s website and its acquiring banks. It encrypts sensitive credit card details, ensuring that information is passed securely from the customer to the acquiring bank, via the merchant.
