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 am trying to list the files (/get_metadata) in my app folder but for some reason I can't set up the correct path. Take a look at this message:
{"error_summary": "path/not_found/", "error": {".tag": "path", "path": {".tag": "not_found"}}}The app folder was automatically created by Dropbox, and after that I created a txt file named text.txt inside it. As you can see, this is the path:
However, when I send the /get_metadata request via curl I receive the error message that the path dosen't exist.
This is the json file - named getMetadata.json - with the parameters:
{ "path": "/home/Aplicativos/optisurface", "include_media_info": false, "include_deleted": false, "include_has_explicit_shared_members": false }This is the curl request I am using:
<?php require_once 'Functions/functions.php'; $token = getToken($_SESSION['uid']); $data = file_get_contents('json/getMetadata.json'); $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Bearer ' . $token[0]->itoken, 'Content-Type: application/json')); curl_setopt($ch, CURLOPT_URL, "https://api.dropboxapi.com/2/files/get_metadata"); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); $response = curl_exec($ch); echo '<pre>'; print_r($response); echo '</pre>'; ?>Can you help me saying what am I doing wrong?
Meanwhile, I used the /list_folder request since it supports root path just by leaving it empty "".
{"entries": [{".tag": "file", "name": "text.txt", "path_lower": "/text.txt", "path_display": "/text.txt", "id": "id:WEoRMx3RGMAAAAAAAAAAJg", "client_modified": "2019-03-08T00:23:18Z", "server_modified": "2019-03-08T00:23:18Z", "rev": "012000000012ec82090", "size": 5, "content_hash": "fe362d76b941f8f883e360e1a7bd26c78d4252c8229621711d6857846a2285f8"}], "cursor": "AAGNZvzM-WGZO5F9XFCBcrTUsT6mhUTRHnnY12-dD6lPgRK-hUZFzy8zMvgbnPMBuvKpIFY-1-QTfe0m_qpJMEE0hUs-JHq_gvzY1gGg2zIEblN0sE8MaGJnnyI_9a5dTi8CwzzfjgwL86mZtZL6UbMi", "has_more": false}But I really want to understand why /get_metadata ins't working because in future code I'll need to access specifics paths.
Thank you in advance!
