How to properly use curl for sending JSON data? or Having trouble with curl sending JSON? Any tips?[

"Having trouble with curl sending JSON? Any tips?"

Hey folks!

I’ve been trying to use curl sending json to an API, but it keeps throwing errors. I’m doing something like:

```bash
curl -X POST http://example.com/api -d '{"key":"value"}'
```

But the server says it’s not valid JSON? Am I missing headers or something?

Also, should I use `-H "Content-Type: application/json"` every time? Feels like I’m overcomplicating it.

Any quick fixes or best practices for curl sending json? Maybe a dumb mistake on my end lol.

Thanks in advance!
