How Do I Send a CURL POST Request with Headers and JSON Data? or What’s the Correct Syntax for a CURL

Ah, the dreaded 400 error with CURL POST requests! Happens to the best of us. One thing that often trips people up is trailing commas in the JSON payload. Your example looks clean, but maybe double-check the actual data you're sending?

Also, try `-v` (verbose) mode and look for the "Request headers" and "Response headers" sections. Sometimes the server gives a hint there.

For debugging, I swear by Postman—it’s way easier to tweak requests and see responses visually.
