REST API - User ID through User Reference?

[Rom]

Hi everyone,

I'm trying to generate a GET request API which I already have working properly. However, I want my API's response to display the User ID of the requester (wherever there is a user reference) and not their full name. Is this possible through the REST API Explorer?

Thanks!

Hi Rom,

yes you can get the user id column as well

sample endpoint here

GET:

URL: https://instanceName.service-now.com/api/now/table/incident?sysparm_query=number%3DINC0010207&sysparm_fields=caller_id.user_name

Response:

{
  "result": [
    {
      "caller_id.user_name": "george.grey"
    }
  ]
}

in the example: I am getting the caller's user_name i.e. User ID

you need to specify the field you want using sysparm_fields

Mark ✅ Correct if this solves your issue and also mark 👍 Helpful if you find my response worthy based on the impact.
Thanks

I am unable to set the caller_id and assignment group. I using the npm package of servicenow-rest-api and thereby I calling the api for incident for creating the new incident. I can create any fields accept the caller_id and assignment group. How to achieve this?
