    <description>I don't see anything clearly wrong with your request. To help troubleshoot this, can you share the full/raw request and response? (Just be sure to redact your app secret.)&lt;BR /&gt;&lt;BR /&gt;Also, this blog post may be helpful:&lt;BR /&gt;&lt;BR /&gt;&lt;A href="https://blogs.dropbox.com/developers/2013/07/using-oauth-2-0-with-the-core-api/" target="_blank"&gt;https://blogs.dropbox.com/developers/2013/07/using-oauth-2-0-with-the-core-api/&lt;/A&gt;</description>

      <title>"No auth function available for given request" return on /token request</title>

      <description>&lt;P&gt;Hi. I send the following form data with the code I got from the authorization page. I use redirect_uri back to my app through localhost.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;However I get the following response (error code 400): "No auth function available for given request".&lt;/P&gt;&lt;P&gt;My request form data looks like this:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Header:&lt;/P&gt;&lt;P&gt;POST /oauth2/token HTTP/1.1&lt;BR /&gt;Host: api.dropboxapi.com&lt;BR /&gt;User-Agent: UnityPlayer/5.5.2f1 (UnityWebRequest/1.0, libcurl/7.46.0-DEV)&lt;BR /&gt;Accept: */*&lt;BR /&gt;Accept-Encoding: identity&lt;BR /&gt;X-Unity-Version: 5.5.2f1&lt;BR /&gt;Content-Length: 177&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Post data:&lt;/P&gt;&lt;P&gt;code=KNJIALLS_WCAAAAAAABSTZP97AYWIZJPX9B1A6CBFUC&amp;amp;grant_type=authorization_code&amp;amp;client_id=&amp;lt;removed for security&amp;gt;&amp;amp;client_secret=&lt;SPAN&gt;&amp;lt;removed for security&amp;gt;&lt;/SPAN&gt;&amp;amp;redirect_uri=http%3A%2F%2F127.0.0.1%3A6756&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I could not find anything on google or the forums, so now I'm trying here.&lt;/P&gt;&lt;P&gt;I can see that auth authorization is missing (Authorization bearer) but the docs said nothing about this, and I don't have a token at this stage in the process anyway.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thanks in advance&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Odin Jensen&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Thanks. The raw request (from Fiddler) is as follows:&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;POST &lt;A href="https://api.dropboxapi.com/oauth2/token" target="_blank"&gt;https://api.dropboxapi.com/oauth2/token&lt;/A&gt; HTTP/1.1&lt;BR /&gt;Host: api.dropboxapi.com&lt;BR /&gt;User-Agent: UnityPlayer/5.6.0f3 (UnityWebRequest/1.0, libcurl/7.51.0-DEV)&lt;BR /&gt;Accept: */*&lt;BR /&gt;Accept-Encoding: identity&lt;BR /&gt;X-Unity-Version: 5.6.0f3&lt;BR /&gt;Content-Length: 177&lt;/P&gt;

      <description>I suspect the issue is that you're missing the "Content-Type" header. It should be "Content-Type: application/x-www-form-urlencoded". Try that and let me know if it doesn't help.</description>

      <description>Can you include the full request and response for that? Please do include the response headers so we can look into it.</description>

      <description>Thanks! That may have just been a transient issue on our side. Can you try once more now? Please share the X-Dropbox-Request-Id again if you still get a 500.</description>

      <description>&lt;P&gt;Hi.&amp;nbsp;I have the sample code ready. Where can I mail it securely? For your convenience, it contains my app secret keys etc.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
