How do I properly use 'curl add header' to include custom headers in my requests?

Hey! Your `curl add header` approach is correct. Stacking `-H` is totally fine.

If you’re debugging, try `-v` to see the full request. It’ll show you if headers are being sent properly.

Another tip: if you’re sending a lot of headers, consider using a file with `--header` like:
`curl --header @headers.txt https://example.com`
Where `headers.txt` contains all your headers. Makes things cleaner!
