Other Information

I’m developing a school cafeteria system using an ESP32 with NFC reader that needs to communicate with my PHP API. The ESP32 sends HTTP POST/GET requests to my API endpoints, but I’m facing issues where the requests are being blocked or redirected to JavaScript challenge pages.

The Problem:

My ESP32 device sends requests tohttps://darwinbrunch.fwh.is/api/nfc.php but receives HTML responses with Cloudflare protection or JavaScript challenges instead of the expected JSON API responses. The ESP32 cannot execute JavaScript, so these challenges prevent the system from working.

What solution or alternative can I do?
