Cannot Get Token from Uber API with Valid Access Key

I've been trying for the past few days to integrate my app with uber, but for some reason during the oauth2 authentication I can't get uber to give me a valid token. I can get an access code but when using curl, I can't seem to get an access token, no matter how I arrange my script. Here's what I have:

<?php

echo $_GET['code']."<br>";
$token = curl_init();
$param = array(
    'client_secret' => 'MY_SECRET',
    'client_id' => 'MY_ID',
    'grant_type' => 'authorization_code',
    'code' => "{$_GET['code']}"
    );
$postData = '';
foreach($param as $k => $v)
    {
       $postData .= $k . '='.urlencode($v).'&';
    }
$postData = rtrim($postData, '&');
curl_setopt($token, CURLOPT_URL, 'https://login.uber.com/oauth/token');
curl_setopt($token, CURLOPT_HEADER, true);
curl_setopt($token, CURLOPT_RETURNTRANSFER, true);
curl_setopt($token, CURLOPT_POST, true);
curl_setopt($token, CURLOPT_POSTFIELDS, $postData);
$returned_token = curl_exec($token);
curl_close($token);
echo $returned_token;

?>

I've double checked my secret and id, both are correct. I can see each time I'm going to get the access code it's something unique, I can see it echoed out on the authorization page I'm redirecting to, but no matter what I keep getting the response as:

{"error": "access_denied"}

It worked for me perfectly. My problem was that I had a difference between the Url Redirect on Dashboard app and The parameter that i send to the request. I fixed it and everything works fine

This error happens because:

Redirect URL
These URLs will be used during OAuth Authentication.
If no redirect URI is included with your request, the default URL will be used.

redirect_uri (optional)
The URI we will redirect back to after an authorization by the resource owner.
The base of the URI must match the redirect_uri used during the registration of your application.

I've also encountered this problem and it looks like I found the reason of it.

Try adding redirect_uri (the same as in app settings) to your request, so your params code should look like this:

$param = array(
'client_secret' => 'MY_SECRET',
'client_id' => 'MY_ID',
'redirect_uri' => 'MY_REDIRECT_URI',
'grant_type' => 'authorization_code',
'code' => "{$_GET['code']}"
);

That helped me, but I hope Uber developers will make this error more specific

Works fine for me. Make sure the Content-Type header is correct. Some services will expect that. (e.g. Content-Type=x-www-form-urlencoded)

Also, can yo share how you are requesting the code? (e.g. which scope are you using when sending the Authorization request, etc).
