OAuth2 access token request invalid - grant_type expecting \"authorization_code"\
Hi, I am trying to obtain an acces token by converting the authorization code. I followed both documentation available in the following links: https://www.dropbox.com/developers-v1/core/docs#oa2...

The "grant_type" parameter value should literally be the string "authorization_code", and only the "code" parameter value should be the authorization code string you received.
That is to say, your parameter line should like something like this instead:
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(array('code'=> $_GET['code'], 'client_id' => "5n5**********aw", 'client_secret' => "zq**********tn8", 'grant_type' => "authorization_code", 'redirect_uri' => 'http://localhost/optiSurface-dropbox/login.php')));
By the way, you linked to the old version of the documentation. For reference, the current version is here: https://www.dropbox.com/developers/documentation/http/documentation#oauth2-token

Problem solved!!
I just realized it's not necessary to include the complete path from the URL. Since the app has permission to access just it's own folder, I just included the file path itself.
So my json file it's like this:
{ "path": "/text.txt", "include_media_info": false, "include_deleted": false, "include_has_explicit_shared_members": false }
Thank you!!

I'm glad to hear you already sorted this out.
To confirm, yes, when using an app with the app folder permission, the paths you use should be relative to the app folder itself. You can get these path values programmatically from other Metadata objects in the 'path_lower' field, e.g., as returned by /2/files/list_folder.
