How to use REST data broker in UI Builder to retrieve ServiceNow data

[gjz]

I have read one of the most efficient ways to retrieve data in UI Builder or a Workspace is by using internal REST APIs to retrieve the data to display, however, I have not been able to find any examples I can follow or seen any documentation or posts on how to do this.  I've looked at some components built for CAB meetings in Service Operations Workspace that do use REST to get data, but a lot of it is hidden and I can't figure out how it is done.

Using a very simple example, how would I create a REST data broker in a workspace to retrieve data from the Incident table and display the data in a repeater?  Can anyone walk me through this?

You can achieve this by creating a Scripted REST API to fetch Incident records, then exposing it via a REST Data Resource (Data Broker) in UI Builder.
Bind the data broker output to a Repeater using @data.<resource>.output, and inside the repeater use @item.value.<field> to display values like number and description.
The key idea is: Data Broker fetches data → Repeater renders the array.
For simple use cases, you can also use “Lookup Multiple Records” instead of REST.

For more details you can refer to the below articles:
