How to create JIRA issue with assignee as unassigned using REST API

Question

I need to create an Issue in JIRA using the REST API from my Java program. While doing this I want to set the Assignee field to Unassigned. Everything that I have found in documentation and other questions has said to leave the Assignee field blank, however that will use the Default Assignee. I want to ensure that the Assignee field is left as Unassigned. How can I do this?

Answer 1

Set the Assignee field to null and it will leave the Assignee field as Unassigned.
