In the V2 documentation it states that the created_by_user_id has been replaced by the creator_user_id. Unfortunately it appears that this is not one of the default fields and also cannot be returned through the include_fields parameter ?
Hey,
Thank you for bringing this to our attention. There has indeed been an oversight with the creator_user_id
field currently being missing from Activities API V2 response. I will shortly post a follow-up once it has been fixed.
Hey,
creator_user_id
is now present in Activities API V2 responses and also included in the API reference page documentation.
