Change Queue for request/issue - Jira Service Desk

I can get the queues but I cannot put the issue in a certain queue or assign the request to someone.

That’s basically what I want. I want to be able to assign someone to a request, either on the creation of the request or after.

The create customer request only allows you to set a reporter (raiseOnBehalfOf) and requestParticipants.

After creating a customer request, given the issue key, you can call Jira Core’s assign issue API - you can either use the REST API approach, or the Java counterpart (since you’re working with server).

Hope this helps.
