I want to claim a task and is sending a post request with body:
{"action":"claim","assignee":"qatester_tools"}
to
http://localhost:8090/api/nuke/v1/runtime/tasks/313

Any suggestions?

Hi,

Can you try to put "Content-Type" "application/json" to the header?

Regards
Martin

Worked thanks Is it correct if it returns a null?Or is there a return expected when claiming a task?

I think there are only response codes:
