Payment Gateway Integration or Online Payment is a method of receiving payment on the customers’ website. It’s a process wherein the customer may display his products or services on his website and the user visiting to the website can pay using his credit / debit card or internet banking account. One of the things you will need if you plan to engage in ecommerce is a Payment Gateway. A payment gateway is an application that allows you to process transactions over the Internet. If you want to sell products and services from a Web site, you need a payment gateway to help facilitate communication between you, your customer and the financial institutions you both belong to. The payment gateway acts as a liaison between your business Web site and the broader Internet.
Payment gateway integration requires a little bit of work. It is a software application that needs to be stored on your server. This means that you may need a little more bandwidth and/or disk space. Check the requirements of the payment gateway to make sure that your current hosting package will be able to handle the increase in technical requirements.
