I am creating a JIRA plugin to fetch the issue-level permissions. Currently, the project-level permissions are working extremely fine but the issue-level permissions are not working. I tried finding a REST API to handle these permissions but, didn’t find anything so I decided to make a custom JIRA plugin to fetch the issue-level permissions of a project and handle them via exposing the plugin through an API.
My question is that what JIRA JAVA APIs do I have to use in order to handle these permissions? Or, is there any other workaround to handle issue-level permissions?
