libcurl upload
I'm trying to upload a file using libcurl. The code reports an OK upload, but the file does not appear. This is the equivalent curl command and it works: curl -X POST https://content.dropboxapi.co...

Dropbox StaffThe 404 is from Dropbox and indicates that the request has not successfully reached a Dropbox API endpoint.
The issue is that you're sending a PUT, but you need to use POST to hit /2/files/upload. Please update your code to use POST and try again.
That worked, thanks. For future readers, libcurl defaults to PUT on CURLOPT_UPLOAD, and Dropbox requires POST. If you follow either libcurl's API description (https://curl.se/libcurl/c/CURLOPT_UPLOAD.html) or example (https://curl.se/libcurl/c/fileupload.html), you must insert this line after setting CURLOPT_UPLOAD:
curl_easy_setopt(curl, CURLOPT_POST, 1L);
The CURLOPT_UPLOAD option will reset it back to PUT if you don't order it this way.
