List account callouts

Lists the callouts attached at account level in Google Ads, which can show on ads across all campaigns. Fresh reads are cached for 10 minutes; exhausted quota may return the last successful read with stale=true. Inherited assets are not included. Preserves Google RMF C.75 account-level callouts.

Update account callouts

Edits existing Google Ads callouts in place; the change applies everywhere that callout is used. Send updates with assetResourceName and the fields to change. An asset is shared: changes affect every attachment using it. Omitted fields stay unchanged. The operation consumes the Google operations budget and invalidates affected cached lists.

Zernio Google Ads connection id.

Match^[a-fA-F0-9]{24}$
adAccountId?string

Platform ad account ID (Google customer ID, digits only). Required when the connection has multiple customers.
