JSON Import - How to add a Request Type

Question

We're trying to mass import tickets from another ticketing system, but I can't for the life of me figure out how to map to a 'Request Type' within JSM.

What does it take to get this field to populate using a JSON import?

I've tried many combinations of using field[], customFieldValues[], customfield_10010: but I can't get anything to actually work.

Hello,

I'm going to consolidate my findings and what I did in this answer.

First of all, to import a custom field we need to know its type. There's an API that retrieves the fields that are available in the Jira cloud instance. If you're logged in to your Jira instance on a browser, then you can simply go to https://{instanceName}.atlassian.net/rest/api/3/field, which will return a JSON list of fields.

If we search for the "Request Type" field we get:

From that we need two things:

* The custom field ID: customfield_10200
* The custom field internal type: com.atlassian.servicedesk:vp-origin

Now, we can construct our sample JSON import file:

{
    "users": [
        {
            "name": "user1",
            "email":"john.doe@mydomain.com"
        }
    ],
    "links": [],
    "projects": [
        {
            "key": "PJK",
            "issues": [
                {
                    "externalId": "OLD-123",
                    "summary": "Test ticket",
                    "description": "This is a ticket description",
                    "reporter": "user1",
                    "status": "Resolved",
                    "resolution":"Resolved",
                    "issueType":"Bug",
                    "components": [
                        "Component 1"
                    ],
                    "created": "2025-11-12T12:34:02.987+0200",
                    "updated": "2025-11-13T15:12:43.458+0200",
                    "assignee": "user1",
                    "history": [
                        {
                            "author": "user1",
                            "created": "2025-11-13T15:12:43.458+0200",
                            "items": [
                                {
                                    "fieldType": "jira",
                                    "field": "status",
                                    "from": "1",
                                    "fromString": "Open",
                                    "to": "5",
                                    "toString": "Resolved"
                                }
                            ]
                        }
                    ],
                    "customFieldValues": [
                        {
                            "fieldName": "customfield_10200",
                            "fieldType": "com.atlassian.servicedesk:vp-origin",
                            "value": "22"
                        }
                    ],
                     "comments": [
                        {
                            "body": "We've started working on this request",
                            "author": "user1",
                            "created": "2025-11-12T12:41:31.125+0200",
                            "properties":[{"key":"sd.public.comment","value":{"internal":"false"}}]
                        }
                    ]
                }
            ]
        }
    ]
}

Notice how in the customFieldValues array I created an object with the following mapped fields:

* fieldName: This is equivalent to the id of the custom field that we got from the API

* fieldType: This is equivalent to the schema.custom property of the custom field that we got from the API
* value: I got this value by going to an already existing issue and getting it from the API. (I've explained it below)

To get a sample value for the custom field:

* Assume the issue has the key PJK-123 and it has a request type that is similar to the one you want to reference.
* Then using the API https://{instanceName}.atlassian.net/rest/api/2/issue/PJK-123?expand=names you'll get a JSON object containing most information related to that issue. 
* Search for the customfield_10200 JSON object, and you'll find the id attribute which is the value that I used.

Hope this helps!
