List action classes

Returns the action classes (user actions that can trigger an app survey) for a workspace. Use the returned ids as distribution.triggers[].actionClassId when creating or updating app surveys. Read-only: this v3 endpoint lists action classes but does not create them — action classes are managed in the Formbricks app (Actions settings) or via the v1/v2 management API.

An empty data array means the workspace has no action classes yet. Triggers are optional, so you can still create an app survey with distribution.triggers: [] (or omit distribution entirely) and attach triggers later via PATCH once an action class exists. Session cookie or x-api-key.
