How Do I Properly Set and Manipulate a Curl Header in My API Requests?

Yo, I feel you on the curl header struggle. One thing that tripped me up was forgetting to add the `Content-Type` header when sending JSON. Like, you gotta do:
`curl -H "Content-Type: application/json" -d '{"key":"value"}' https://example.com`

Also, if you’re on Windows, escaping quotes can be a pain. Use double quotes for the header and escape inner quotes with a backslash.

For debugging, I use `curl -i` to see the response headers. Helps a ton to figure out what’s going wrong.
