A developer token from Google allows your app to connect to the Google Ads API. To participate in the Google Ads API Beta, you must already have an AdWords API developer token. You will use this exact same developer token from the AdWords API for the Google Ads API.
You can retrieve your developer token by signing in to your manager account and then going to the Google Ads API Center page (Tool icon > SETUP > Google Ads API Center).
Your pending developer token must be approved before using it with production AdWords accounts.
