5-Hour Paystack Gateway Integration

I have a live website that is ready for payments; what it still lacks is a fully working Paystack gateway. I need you to wire it up, test it end-to-end, and hand it back to me within the next five hours.

You will receive immediate access to:
• the repository (git) and its current checkout page
• my Paystack test and live secret/public keys
• a staging URL plus sample orders for quick verification

Your task is to embed Paystack’s inline or pop-up flow, verify each transaction server-side through the Paystack API, and update the order status in the database. A concise README explaining any new environment variables or routes you add is also required.

Acceptance criteria
• User can complete a payment on the site, see a clear success or failure message, and the transaction logs correctly in both our dashboard and Paystack’s.
• All calls are HTTPS, keys are loaded from env variables, and there are no console or server errors.
• Completed pull request or zipped source delivered before the five-hour mark.

If you are confident in hitting this deadline, let’s get started right away.
