Login Api AdWords in PHP (Codeigniter) without auth.ini
First of all you can find info (including the service endpoint url) about using the Analytics API as a test account here: https://developers.google.com/adwords/api/docs/test-accounts
Secondly, the readme states to use the following method to set your service:
$campaignService = $user->getCampaignService('v201306', 'https://adwords.google.com');Lastly it seems the parameters you are using to initial the AdWordsUser object are a bit off, the readme also states the following:
$user = new AdWordsUser(NULL, NULL, NULL, $developerToken, $applicationToken, $userAgent, $clientCustomerId, NULL, NULL, $oauth2Info);
