How can I access the Driver field of the release versions

[Juan Manuel Alarcon Castrillon]

Hi, I'm trying to set up an automation for when a Release version is created, it will get auto assigned to an specific person, but I can't seem to find the way to do it, I've tried using the smart value, {{issue.driver}} but it does not work, I also used an API call to check how the name is being send but this was the payload I got

    "name": "R2025-09-08",

    "archived": false,

    "released": false,

    "startDate": "2025-09-08",

    "releaseDate": "2025-09-08",

    "overdue": true,

    "userStartDate": "07/Sep/25",

    "userReleaseDate": "07/Sep/25"

No Driver name

Hello @Juan Manuel Alarcon Castrillon 

With the API endpoint you can use the expand Query parameter to include the Driver name in the output.

Hi Thanks, I Got the driver now, but how can I set it on the automation?

Based on the discussion in this 2024 question it does not appear to be possible to set the Driver field via automation or the API.

I am not familiar with DRIVER as a field associated to a version.  Here is the JSON Representation of one of my versions.  

"self": "https://splitdimedata.atlassian.net/rest/api/3/version/10000",
      "id": "10000",
      "description": "And So It Begins",
      "name": "Go Live July 7",
      "archived": false,
      "released": false,
      "startDate": "2025-01-01",
      "releaseDate": "2025-07-07",
      "overdue": true,
      "userStartDate": "31/Dec/24",
      "userReleaseDate": "06/Jul/25",
      "projectId": 10013

DOH!  Thanks to the other answer posted, I check the REST Documentation and DRIVER is a Property

https://splitdimedata.atlassian.net/rest/api/3/version/10000?expand=driver
