REST API access to ticket history

Dear Zammad Team,

we are creating deep statistics about the usage of our Zammad instance.
Therefore we’d need not only access to the current ticket data, but also to the full change history of the tickets.

In the Zammad UI it’s accessible via the Ticket Sidebar:

Can you please provide such a REST API endpoint?
If it’s already there, can you please add it to the documentation ( Ticket endpoints — Zammad documentation )?

Thanks so far!

Best Regards
Alexander Lenz
