See [App campaigns](https://support.google.com/google-ads/topic/10011871) for more
information about App campaign types.

You can use [`AdsApp.mutate`](https://developers.google.com/google-ads/scripts/docs/concepts/mutate) to
create a new campaign by providing a
[`CampaignOperation`](https://developers.google.com/google-ads/api/reference/rpc/v26/CampaignOperation) with a `create`
operation. See
[Operation types: create](https://developers.google.com/google-ads/scripts/docs/concepts/mutate#create).
