How to curl post a URL with proper syntax and headers? or What’s the correct way to curl post a URL?

"Help! Can't get my curl post a url command to work – what am I missing?"

Hey folks,

Trying to curl post a url but keep getting errors. My syntax looks like this:

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

But it’s either throwing a 400 or just ignoring the data.

Am I missing headers? Do I need `-H "Content-Type: application/json"` or something? Also, should I use `--data` instead of `-d`?

Kinda new to this, so a step-by-step breakdown would be *chef’s kiss*.

Bonus Q: Any best practices for curl post a url? Like, should I always include certain headers?

Thanks in advance! 🙏
