To get started, check out the performance max campaigns selector on the AdsApp. Once you've selected a PerformanceMaxCampaign, you can perform common operations like pausing or enabling the campaign, as well as selecting and modifying most asset types in asset groups. You cannot modify text assets this way, and you cannot create new campaigns or asset groups through scripts.
Performance Max retail campaigns are supported in only a limited fashion as listing groups cannot be managed via Scripts.
For more information about Performance Max campaigns in general, check out the complete help center article.
If you have any questions or feedback, please leave a post on our forum or send a message to our support alias [email protected] so that we can help.
