I am using BingAds-PHP-SDK to get authenticated user detail.
Firstly done Authentication with OAuth successfully and get authentication token and refresh token.
But when call GetUser() returning following Exception.
Main Exception detail:

    [AdApiFaultDetail] => stdClass Object (

                [Detail] => 
                [ErrorCode] => InvalidCredentials
                [Message] => Authentication failed. Either supplied credentials are invalid or the account is inactive
           )
       )
   )
)
