YouTrack REST API, get issue history

Question

I am trying get specific information about ticket activities.

I wanna know next things:

1. All assignee change events
2. All sprints change events
3. All story points change events
4. All status change events

I built next URL:

issue_history_activity_url = (f"{base_url}/issues/{issue_id}/activities?categories=CustomFieldCategory&fields=field(name),author(login),timestamp,added(name),removed(name)")

It gives me almost everything except the assignee change events. I tried every category from documentation, nothing works.

Please help. GPT chat couldn't help too.

Answer 1

I have found assignee in ProjectCategory custom fields. It is really a little bit counterintuitively.
