  • Updated 5 months ago
This is my Code for getting token.
$code=$_REQUEST['code'];
$APPKEY="u8hj81KeQ9uQDyA1PBTTgw";
$req='https://platform.devtest.ringcentral.com/restapi/oauth/token';
$post = array (
'grant_type' => 'authorization_code',
'code' => $code ,
'redirect_uri' => 'http://localhost/token.php');

$ch = curl_init($req);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$apiKey = base64_encode($APPKEY);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Authorization: Basic ' . $apiKey,
'Accept: application/json',
'Content-Type: application/x-www-form-urlencoded'));

curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);


$response = curl_exec($ch);
curl_close($ch);
$r=json_decode($response, true);





And the Response is 
array (size=3)
  'error' => string 'invalid_client' (length=14)
  'error_description' => string 'Invalid client: ' (length=16)
  'errors' => 
    array (size=1)
      0 => 
        array (size=3)
          'errorCode' => string 'OAU-153' (length=7) 
          'message' => string 'Invalid client: ' (length=16)



I am using the same Client ID for getting authorized Code.
Please Help me what is Wrong.

Refresh Token using sdk:

 SDK sdk = new SDK( "ktx884**********-TL-O3Q",
               "RNLRm1zYR**************4JxrC5CTjKpWF3KwRlFPg",
               "https://platform.devtest.ringcentral.com";,
               " ",
               ""); 

Dictionary<string, string> obj = new Dictionary<string, string>();

  obj.Add("refresh_token", CurrentUser.RCRefreshToken);
  obj.Add("grant_type", "refresh_token");
                   
 var request = new Request("/restapi/oauth/token/",obj);                    
  var responseToken = sdk.Platform.Post(request);

The sample code you post is not PHP. Could you please provide more information?  If you tell me the programming language, I might be able to provide with you some sample code.

A new thread is preferred. Because this one is old and it's about PHP.  I answered this question in another thread.
