How Do I Properly Use CURL --POST to Send Data in a Request? or What’s the Correct Syntax for CURL --

JSON in CURL --POST is a pain because of escaping. If you’re on Windows, use `\"` for quotes, or better yet, put the JSON in a file and use `-d @file.json`.

Form data is simpler—just `-d "key=val"`. No headers unless the API demands it.

If it’s still failing, maybe the endpoint is HTTPS and you need `-k` to ignore cert errors (not recommended for prod tho).
