Today we’re announcing the v3_1 release of the Google Ads API beta. To use the v3_1 features, please update your client library. If you are upgrading from v1 or v2, some of your code may require changes when you switch to the new v3 endpoint. Please see the migration guide for more information on breaking changes.

Here are the highlights:

• Added support for retrieving campaign optimization score in Campaign.optimization_score.
• Added new conversion action categories to ConversionActionCategory. See the release notes for details.
• Added a new service OfflineUserDataJobService which supports asynchronous upload of Customer Match data and store sales (direct upload) data. These features are whitelisted.
• Added support for retrieving the paying manager customer with PaymentsAccount.paying_manager_customer when making a request to PaymentsAccountService.ListPaymentsAccounts().
