ServiceNow API parameter not being honored

[kcritchnau]

I'm attempting to send a POST request via Postman to the incident table using the following body:

{"assignment_group": "AppSvcs_OES_OperationalApps", "cmdb_ci":"AMIGO 3", "caller_id": "KCRITCHN", "urgency": 2, "impact": 2, "category": "Application", "subcategory": "Functionality", "short_description":"Postman Test", "description":"Postman Test" }

Eventually this will be made as an AJAX request from my application, but for now I'm using Postman to explore the API functionality.

I have set the sysparm_input_display_value parameter to true, but none of the display values are being set. Here's the URL I'm using: {service-now instance URL}/api/now/table/incident?sysparm_input_display_value=true

Is there anything I'm missing here?

Adding the version to the URL didn't seem to help. Here's the response I'm getting:

As you can see, the cmdb_ci, assignment_group, and other fields specified in the request are not being set.
