Hey! I’ve had similar issues with curl sending json. One thing that tripped me up was the server expecting a specific JSON structure. Maybe try this:
```bash
curl -X POST -H "Content-Type: application/json" -d '{"key":"value","another_key":"another_value"}' https://example.com/api
```
Also, if you’re on Windows, escaping quotes can be a pain. Try using PowerShell instead of cmd.
If you’re still stuck, try testing the request with Postman first. It’s way easier to debug there.
