Missing required parameter: scope when using $authorizationUrl

[Alan Coleman]

 Hello everyone,

I'm successfully generating $authorizationUrl using the code below. However on using that URL I'm receiving the error:

Missing required parameter: scope.

OAUTH2_SCOPE is being declared as a constant in the AdWordsUser class so I'm confused as to why it's not being carried across.

I'm working with the following:

Library: adwords_api_php_4.5.1
Version: v201306

As Always, any ideas would be appreciated.

 function GetOAuth2Credential($user, $callbackUrl) {
       $redirectUri = $callbackUrl;
       $offline = TRUE;
       // Get the authorization URL for the OAuth2 token.
       // Pass in a redirect URL back to the application,
       // Passing true for the second parameter ($offline) will provide us a refresh
       // token which can used be refresh the access token when it expires.
       $OAuth2Handler = $user->GetOAuth2Handler();
       $authorizationUrl = $OAuth2Handler->GetAuthorizationUrl(
      $user->GetOAuth2Info(), $redirectUri, $offline);

   return $authorizationUrl;
}   

 // Create a new user and set the oAuth settings
  $user = new AdWordsUser();
  $user->LogAll();
  $user->SetOAuth2Info(array(
      "client_id" => $clientId,
      "client_secret" => $clientSecret
       ));
 // Generate an authorization URL given the callback URL
        $authUrl = GetOAuth2Credential($user, $callbackUrl);

There doesn't appear to be any issues with the code you're providing.

Can you inspect the OAuth2Handler class to see if it has the scope property set?

var_dump($user->GetOAuth2Handler());

Also, double check that you've not changed the OAUTH2_HANDLER_CLASS specified in the settings.ini.

 Hi Paul,

Thanks very much for replying.

var_dump($user->GetOAuth2Handler()); Does indeed reveal that the scope variable in SimpleOAuth2Handler is null. 

I've hard coded the variable in Oauth2Handler.php

  public function __construct($server = NULL, $scope = 'https://adwords.google.com/api/adwords/') {
    $this->server = $server;
    $this->scope = $scope;
  }

This seems to work although I'm unsure as to why $scope isn't being picked up elsewhere. Is this an acceptable solution?

Also, the OAUTH2_HANDLER_CLASS specified in the settings.ini. is coded out, is this correct?

Thanks again.

Hi Alan,

This looks as though there's an issue with your settings.ini, please compare to the original settings.ini and confirm the changes are correct. Yes the OAUTH2_HANDLER_CLASS should be commented out as it defaults to the SimpleOAuth2Handler.

The scope should be configured by the AdWordsUser object, from the class constant. Is there a reason why your system wouldn't honor the class constant? Are you extending the AdWordsUser or have you changed the GetDefaultOAuth2Handler implementation?
