Hi Tayyab,

It seems you selected the wrong Platform type (other types than the "Server-only/(No UI)" for your RingCentral app. If your Web app uses the PHP SDK to authenticate and access RingCentral APIs directly, you must select the "Server-only/(No UI)" for the Platform type.

Try to create a new app with that platform type and test again.

Kind regards,
Paco

1) You still receiving the same error which related to wrong platform type. So I am not sure if you have changed the appKey and secret accordingly.

2) I saw your other questions relating to problem with sending fax from PHP code and there you mentioned about using 3-leg authentication. If this is the same project, then you probably don't need to create a new app with "server-only" platform type. But you should follow the instructions from this demo project to get the access token from your client side and pass the token to the php via session.

https://github.com/ringcentral/ringcentral-demos-oauth/blob/master/php/index.php

//set the access token using the auth objectif (isset($_SESSION['sessionAccessToken'])) { $platform->auth()->setData((array)json_decode($_SESSION['sessionAccessToken']));}

Hope this helps,
Paco

If the accessToken is expired, then you would HAVE to Authorize the same way as you did earlier using the Authorization Code Flow ( 3 Legged OAuth )

Since the accessToken are valid for 1 hour and if you are trying to refresh the tokens before the TTL expiry then you are GOOD to refresh the accessTokens. But once the accessTokens are expired you would no longer be able to refresh the expired token and hence you would need to re-authorize again

Are you following the API ref for Refresh:
https://developer.ringcentral.com/api-docs/latest/index.html#!#RefRefreshTokenFlow
