I m trying configure the API ZOHO in my PHP application.

* 1 step:

Register your access in  https://accounts.zoho.com/developerconsole, here create your ID_CLIENT to access.

2* step:

Install and configure API ZOHO 

composer require zohocrm/php-sdk

*3 step

Obtain code grant with request GET

$urlOauth=" https://accounts.zoho.com/oauth/v2/auth?client_id=".$idCliente."&scope=".$permisos."&redirect_uri=".$urlRedirect."&response_type=".$tipoPeticion;

* 4 step:

you should obtain the code in the response of 3 step by JSON and then you will try the authentication

$codigo=$_GET['code'];

//echo("Codigo: ".$codigo);

ZCRMRestClient::initialize();

$oAuthClient = ZohoOAuth::getClientInstance();

$grantToken = $codigo;

$oAuthTokens = $oAuthClient->generateAccessToken($grantToken);

in function "getUserEmailIdFromIAM($accessToken)" return this error in JSON { ["response"]=> string(5) "error" ["cause"]=> string(18) "INVALID_OAUTHSCOPE" } when try make request with access_token.
