Lists the asset groups of every ad account your organization connects, newest first.

## Google Ads only, and Performance Max only

An asset group is Performance Max’s delivery container. A Performance Max campaign has **no ad groups and no ads**: the asset group holds the headlines, images, videos and audience signals that Google’s automation assembles into placements itself.

Every other provider lists nothing here, and that is normal rather than a failure.

## A sibling, not a child

An asset group is a child of a **campaign** and a **sibling** of an ad group — not a layer beneath one. That is why it takes `campaignId` and never `adGroupId`, and why a Performance Max campaign answers nothing under `/observe/ad-groups` or `/observe/ads`.
