Hey! Common issue with curl http post. You might need headers, especially if the API expects JSON. Try this:

`curl -X POST https://example.com/api -H "Content-Type: application/json" -d '{"key":"value"}'`

If it’s still failing, check if the endpoint requires auth (like -H "Authorization: Bearer token"). Also, tools like Postman or Insomnia can help debug—they show raw curl commands too!

yo, had the same prob last week. For curl http post, missing headers is usually the culprit. If you’re sending JSON, gotta tell the server with `-H "Content-Type: application/json"`.

Also, try `-v` flag to see verbose output—helps spot errors.

Here’s a working example:
`curl -X POST https://example.com/api -H "Content-Type: application/json" -d '{"name":"test"}'`

If it’s still not working, maybe the API docs are trash lol.

For curl http post, your command looks fine for form data, but if the API expects JSON, you gotta tweak it. Try:

`curl -X POST https://example.com/api -H "Content-Type: application/json" -d '{"key":"value"}'`

Pro tip: Use `jq` to prettify JSON responses (`curl ... | jq`). Also, websites like reqbin.com let you test curl commands online—super handy for debugging!

Sounds like a headers issue. Some APIs are picky. For curl http post with JSON, you NEED the Content-Type header. Example:

`curl -X POST https://example.com/api -H "Content-Type: application/json" -d '{"key":"value"}'`

If you’re still stuck, try `curl --trace-ascii debug.txt` to log everything. Also, check if the API needs HTTPS or a user-agent header.

Bro, curl http post can be tricky. Your command works for form data, but JSON needs headers. Try this:

`curl -X POST https://example.com/api -H "Content-Type: application/json" -d '{"key":"value"}'`

If it fails, maybe the server expects something else. Use `-v` to see the full convo. Also, check out curlconverter.com—it turns browser requests into curl commands.

omg thanks everyone!! the JSON header fixed it 😭

but now i’m getting a 403 error... do i need an API key or something? how do i add that to the curl http post?

also, the `-v` flag was super helpful—saw the server was rejecting it. any tips for auth stuff?

(ps. reqbin.com is a lifesaver, ty!!)

Ah, the classic curl http post struggle. Your command’s fine for form data, but JSON needs headers. Here’s the fix:

`curl -X POST https://example.com/api -H "Content-Type: application/json" -d '{"key":"value"}'`

If it’s still not working, the API might need auth or a different endpoint. Tools like Postman or httpie (simpler than curl) can help test faster.
