Requirement : OpenCart Extension Development Please carefully read the below requirement and only qualified experienced developers bid this project. Our requirements are very simple, we are making a bridge to communicate from OpenCart extension to our payment gateway which is based on the merchant's API's credentials and payment channel configurations. It means the extension should send the merchant's configured parameters to our payment gateway URL and it returns to the merchant's website with payment status. Based on payment status at the merchant website order should be processed as per following results. Example; If payment is captured, the order should be processed. If payment is not captured, the order should be cancelled. And also if possible store the response parameters in order notes like Payment ID, Transaction Status & etc. All logic, hashing and encryption are with us in fact we have already developed WooCommerce plugin for the same which you can take as reference.
