How do I properly send a POST request in curl? or What’s the correct way to make a POST request in cu

Bro, servers can be so finicky. For a post request in curl, double-check:

1. Is the endpoint correct?
2. Are you using HTTPS? Some APIs reject HTTP.
3. Maybe the server expects `-d @file.json` instead of inline JSON.

Also, try `curl --trace-ascii debug.txt` to log everything. Lifesaver for weird errors.
