How to Properly Use `curl` to Pass a File Object in a Request?

Hey! You're on the right track with the `-F` flag for `curl pass file object`. If the server expects a specific field name, you can just replace `"file"` with whatever field name they require. For example, if they want `"document"`, you'd do:
```bash
curl -F "document=@path/to/file.json" https://example.com/upload
```
Also, if the server expects JSON content-type, you might need to add `type=application/json` like this:
```bash
curl -F "file=@path/to/file.json;type=application/json" https://example.com/upload
```
Hope that helps!
