OAuth2 access token request - Basic authentication not working
I am trying to integrate Dropbox in my webservice. However I decided to use a direct integration instead of any APIs as I need a limited number of functions only and not used to code object orientate...
Thanks! The API is indicating that the request wasn't valid. This particular error message isn't too specific, but it seems to be indicating that the necessary information wasn't given.
Looking through your code, you appear to be sending the parameters as JSON. The /oauth2/token endpoint expects application/x-www-form-urlencoded POST parameters though (with the app key and secret in particular optionally sent in the Authorization header instead).
Please update your code to send the rest of the parameters as application/x-www-form-urlencoded POST parameters instead.

That appears to be the response headers only. Can you print the response body?
I managed to get additional information from the HTTP request:
{"url":"https:\/\/api.dropboxapi.com\/oauth2\/token","content_type":"application\/json","http_code":400,"header_size":385,"request_size":350,"filetime":-1,"ssl_verify_result":0,"redirect_count":0,"total_time":0.287188,"namelookup_time":0.004172,"connect_time":0.018384,"pretransfer_time":0.053378,"size_upload":23,"size_download":97,"speed_download":337,"speed_upload":80,"download_content_length":-1,"upload_content_length":23,"starttransfer_time":0.287049,"redirect_time":0,"redirect_url":"","primary_ip":"162.125.66.7","certinfo":[],"primary_port":443,"local_ip":"85.13.153.199","local_port":45981}

This helps me very much!
I tried to fix this with a simple but dirty solution
$response = file_get_contents('https://my_app_id:my_app_key@api.dropboxapi.com/oauth2/token', FALSE, http_build_query($parameters));Which seems to be almost working (at least detects if I am missing parameters, so the authentication seems to work).
The result of the function http_build_query is
code=authcodegoeshere&grant_type=authorization_code&redirect_uri=https%3A%2F%2Fmydomain.com%2Ffile.php
and should be in the correct format.
The updated error says this:
:{"error_description": "unknown field \"var1\"", "error": "invalid_request"}Thank you very much for your help!
Edit: Got it! Created a new complex function accessing the data with curl. Thank you very much for your help, this helped me very much!
