Hi Jip, Performance Max campaigns require certain minimum Assets to be attached to the campaign. You can see all the requirements on this guide.
Using one of your errors as an example: "assetGroupError": "NOT_ENOUGH_HEADLINE_ASSET" This means you are not adding enough Text Assets to the Campaign. Based on the table from the guide you need a minimum of 3 Text Asset. On your query you are only sending one create operation for the Campaign but not telling it what assets to use. { "operations": [ { "create": { .... } } ] } First you need to create these Assets using the Asset endpoint sending an Asset Operation. You will need to do this for all the Assets required. Then you need to also include the AssetGroupAsset Operations as part of the Campaign request you are sending.
