Listing All JIRA Transitions via API

Question

I\'m looking to set up smart commits in JIRA, but my developers want to know all the options for their transitions. In order to help them, I\'d like to print a cheat-sheet

Answer 1

You can get all transitions for project with /rest/api/2/project/{projectIdOrKey}/statuses endpoint. Here is response example, look at "statuses" array:

[
    {
        "self": "http://localhost:8090/jira/rest/api/2.0/issueType/3",
        "id": "3",
        "name": "Task",
        "subtask": false,
        "statuses": [
            {
                "self": "http://localhost:8090/jira/rest/api/2.0/status/10000",
                "description": "The issue is currently being worked on.",
                "iconUrl": "http://localhost:8090/jira/images/icons/progress.gif",
                "name": "In Progress",
                "id": "10000"
            },
            {
                "self": "http://localhost:8090/jira/rest/api/2.0/status/5",
                "description": "The issue is closed.",
                "iconUrl": "http://localhost:8090/jira/images/icons/closed.gif",
                "name": "Closed",
                "id": "5"
            }
        ]
    }
]

But it doesn't give you exactly list of transitions that any issue can take at any time, and I'm not sure that such method exist in API.
