Camunda Rest API is not supporting to filter historic tasks by multiple candidateGroup or candidateUsers.
My input would be like either candidateGroup=“Team1, Team2, Team3” or candidateUsers=“Usr1,Usr2,Usr3”.
How to achieve this inorder to fetch the historic tasklist?
Hi @aravindhrs,
As you write, this is currently not a feature of the Java or REST API. You can implement a custom or native query (https://docs.camunda.org/manual/7.9/user-guide/process-engine/process-engine-api/#native-queries) on the Java level and then expose a custom REST endpoint that exposes it.
It would also make a useful addition to the Camunda REST API, so please let us know if you would like to contribute this functionality.

Yeah sure @thorben
I have already started the development. And I’m happy to contribute to camunda. Will let you know once the implementation done
