Exchange Code to Token Failed

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.

$post = array (

$ch = curl_init($req);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$apiKey = base64_encode($APPKEY);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Authorization: Basic ' . $apiKey,

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

Do you get the correct result? If no, what's the error message?

Why don't you use the official SDK instead? https://github.com/ringcentral/ringcentral-php

If you want to write your own, please reference https://github.com/ringcentral/ringcentral-php/blob/ac9984a8ae2e41239dfe84ae4f698f8a16b22417/src/Pla... and https://github.com/ringcentral/ringcentral-php/blob/ac9984a8ae2e41239dfe84ae4f698f8a16b22417/src/Pla...

If you have problem using the official SDK, you should post the problem here instead of writing your own solution. Because your own solution will have that grant issue too.

Just post the problem in the devcommunity and you will get the help as soon as we see it. Probably much faster than the email help. Here is the preferred place for us to help developers.

But first of all, I need to know what kind of problem are you having with the official SDK.

If it is a web application, you cannot use the password flow.

Please use the authorization code flow instead. Demo code: https://github.com/ringcentral/ringcentral-demos-oauth/tree/master/php

Tutorial in Node.js: https://ringcentral-tutorials.github.io/authorization-code-flow-nodejs-express-demo/

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);

Getting Error:Access Expired

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.
