Update Task Info using rest api

hi,
I want to update items in below picture, but I don’t know how to change them using rest api(Item1,2,3,4)?

also I want to get History of task (item 5), but I don’t how to get them?

Hi,
I’d suggest looking into the following documents:
Update a Task | docs.camunda.org - 1,2
Identity Links | docs.camunda.org - 3
Claim Task | docs.camunda.org - 4

The history I’m not sure about, probably those 2: Get Task Comments | docs.camunda.org
Get User Operation Log (Historic) | docs.camunda.org with taskId specified
Hope that helps.
