Integrating new payment gateway
To integrate a new payment gateway create a new class in the sitekly/app/Libraries/Payments directory.
Use the sitekly/app/Libraries/Payments/sample.php class as a starting point for your new class, it contains all the required code along with comments telling you what to add and where.
You just need to specify the data that will be sent to the payment processor and add payment notification validation.
The payment system supports both one-time payments and recurring payments.
