Third Party Payment Gateway Integeration Manual


Now Any payment gateway can be integrated. For that you have to add the payment gateway to site. Its just simple to fill the form and provide some essential data to integrate any payment gateway.

INTEGRATION FORM:

Payment Gateway Name: Name of the Payment Gateway that you want to integrate with the site. This name is also used to display the payment gateway name on the submit button if the payment gateway image is not added.

Description: Here you can give the brief information about the payment gateway.

URL to your third party script: This is the URL of your php file that will handle the payment gateway code and send the date to the payment gateway.

For example: you want to integrate the payment gateway “Paypal”. Then first create the paypal folder and then add a php page to call the “Paypal form and send data to the paypal. Lets say you have created the index.php file. Our System will send the all-necessary data to this page. Here you can get the necessary data to manipulate the form and send it to the payment gateway. So you will have to enter the full URL of your php script. Like http://www.yourdomain.com/payment_gateway/paypal/index.php .

Method to call page: This method will be used to submit all necessary data to you php script page.
For example: if you select the Get method then the data will be send through the get method to your php script and you can get all the data using $_GET in your php script.

if you select the POST method then the data will be send through the get method to your php script and you can get all the data using $_POST in your php script.

Payment Button: Here you can add the payment gateway button that will be visible on the front end where ever you want the payment gateway to be appearing.

How the System Works?
