obsn1000/APPLEPAYER ? reverse-engineered prompt

Build me a web app for Apple Pay support that lets me validate merchant sessions, generate Apple Wallet passes, create and check K BAN codes, and download mobile configuration files.

I want a simple browser based dashboard where I can paste in the needed values, call the endpoints, and see clear success or error messages. It should have basic security with an API key, rate limiting, and sensible validation so bad requests don’t break things. Please make it work with the required Apple certificates and environment settings, and include a clean demo page I can open at localhost to test everything.

If it helps, look up the current Apple Pay and Wallet docs online so the setup and certificate handling are correct. Also make sure it can run locally and in production without a lot of extra manual steps.
