How Do I Properly Set a Custom curl Header in My Request? or What’s the Best Way to Pass Headers Usin

curl header issues? Classic. Your command’s fine, but maybe the server’s case-sensitive. Try `-H "content-type: application/json"` (lowercase).

For multiple headers, stacking `-H` is the only real option. Annoying, but works.

Debugging tip: Use `nc -l 8080` to spin up a local server, then curl it to see *exactly* what’s being sent. Lifesaver for header mysteries.
