Introduction
The Payment Processor Tool is used to integrate different payment gateway methods. Currently, this tool supports Stripe and Paypal. Users can modify the product details to generate a customised payment link. The payment link can be conveniently sent to customers via email or any configurable ways, allowing them to perform payment.
This plugin is created with the aid of Stripe API Documentation and Paypal API Documentation.
