Hello, i use the library https://github.com/ringcentral/ringcentral-php.

$apiResponse = $rcsdk->platform()->post('/restapi/oauth/token', [

    'refresh_token' => $data['refresh_token'],

    'grant_type' => 'refresh_token',

    'endpoint_id' => $_ENV['RC_AppKey']

]);


I get a response from the server, Unsupported grant type. What is the problem?

Hi Alexey,

Why do you want to change the refresh token? After logged in, if the access token expired, you can call $rcsdk->platform()->refresh() to refresh the access token. If the refresh token also expired, you just need to call $rcsdk->platform()->login($option) again.

You can always check if the access token and the refresh token is still valid or not to decide what to do by calling $rcsdk->auth()->accessTokenValid() or $rcsdk->auth()->accessTokenValid(), respectively.

Alexey,

Can you verify that your app has the "Refresh Access Token" flow grant which is required to refresh your token? I will look like the following in the "Settings" > "OAuth Settings" > "Authorization Flows" section of your app configuration as shown below:



Thanks,
John
Instead of the code you post, could you please try '$rcsdk->platform()->refresh()' instead? Because the PHP SDK already provides method for refreshing.
