Google Ads Developer Blog: AdWords scripts now uses OAuth2

Google Ads Developer Blog: AdWords scripts now uses OAuth2: We are glad to announce that AdWords scripts now uses OAuth2 for authorization. In addition to streamlining the authorization flow, this change also increases the limit of number of scripts per user to 250.

When you create a new script, you will be prompted to authorize the script to access your account on your behalf. When you click the “Authorize Now” button, a “Request for Permission” dialog that lists the Google services required by your script will be displayed. You can review and grant the requested permissions to authorize the script. As of now, AdWords scripts request permissions for the following Google services:

• Send email as you 
• View and manage your spreadsheets in Google Drive 
• Manage your AdWords campaigns
• Perform these operations when you are offline.

As we add support for more Google services in AdWords scripts, this list may expand to include newer services.

To list all the scripts you have authorized:

• Sign in on the Google Accounts homepage.
• Click the Security tab, and select "Manage access" under "Connected applications and sites." This page lists the third-party sites you selected to always approve for Google authentication. Your authorized AdWords scripts can be found on this page.

If you wish to revoke access to a script, you may do so by clicking the corresponding “Revoke Access” button.
