HOW TO INTEGRATE A PAYMENT GATEWAY INTO A WEBSITE? Please use detail.

Answer 1

To integrate a payment gateway into the website we have to used a three types of integration method on this,so the payment gateway is a service that authorizes and processes payments in online and brick-and-mortar stores. A gateway serves as a portal to facilitate transaction flow between customers and merchants.

The three type of integration method is;

Hosted gateway

A hosted payment gateway acts as a third party, as it requires your customers to leave your website to complete a purchase.

How to integrate: Integration guides are generally open on the vendor’s websites. As an example of the integration of a hosted gateway, you may have a look at the PayPal Express Checkout Guide. Basically, you receive a piece of JavaScript code that places a button on your website. Clicking on the button will activate PayPal’s REST API and checkout flow to process the transaction.

Direct Post method

Direct Post is an integration method that allows a customer to shop without leaving your website, as you don’t have to obtain the PCI compliance. Direct Post assumes that the transaction’s data will be posted to the payment gateway after a customer clicks a “purchase” button. The data instantly get to the gateway and processor without being stored on your own server.

How to integrate: A vendor would set up the API connection between your shopping cart and its payment gateway to post the card data.

Non-hosted (integrated) method

An integrated payment gateway allows you to keep the user at your website during the purchase. Non-hosted payment gateway providers allow for integrating via APIs.

How to integrate: Non-hosted payment gateways are integrated via APIs to your server. Consequently, it will require an engineering team to perform the integration. Most vendors have well-documented integration guides, API references, or developer portals.
