Project description:
"I have a PHP-based script that is already live and I now need it to accept payments through the Payments gateway. My merchant account with them is active, and all API credentials have been issued, so the task can move straight to coding and testing.

The integration is for a single, one-time charge flow only—no subscription logic or recurring billing is required. What I expect from you is a clean drop-in module (controller + callback/​webhook handling) that:

• captures the amount and order details sent from my script
• redirects or presents the secure Payments checkout as per their docs
• records the success/​failure response and updates my orders table accordingly
• returns a clear success page (and a fallback error page) to the user

Please keep the existing MVC structure intact, comment your code clearly, and include a quick README describing any new environment variables or routes. Once you can demonstrate a successful test transaction in sandbox and produce the call/response logs, the job is done." (client-provided description)
