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

Hey! You're on the right track with the `curl add header` stuff. Stacking `-H` flags is totally fine for multiple headers. Like you said:
`curl -H "Header1: value1" -H "Header2: value2" https://example.com`
That’s the way to go.

If you’re worried about headers not being sent, try using `-v` (verbose mode) to see the full request and response. It’ll show you exactly what’s being sent.

Also, check out Postman if you want a more visual way to test APIs with custom headers. It’s super handy for debugging!
