How to Create a Data Broker Server Script to Retrieve a Specific Property Value

[sarah_bioni]

In this article, we’ll demonstrate how to create a Data Broker Server Script that retrieves the value of a specific system property by its name. This is particularly useful when building Workspace experiences that require dynamic property values through Data Resources.

Step 1: Define the Data Broker Properties

Add a property to capture the name of the system property you want to retrieve:

[

{

"name": "property_name",

"label": "Name of property",

"description": "Name of the required property",

"readOnly": false,

"fieldType": "string",

"mandatory": true,

"defaultValue": ""

}

]

This ensures the Data Broker accepts the property name as input.

Step 2: Implement the Server Script

Use the following script in your Data Broker:

function transform(input) {

var grProperties = new GlideRecord('sys_properties');

grProperties.addQuery('name', input.property_name);

grProperties.query();

if (grProperties.next()) {

return grProperties.getDisplayValue('value');

} else {

return "Property name was not found";

}

}

Key Points:

• The script queries the sys_properties table.
• If the property exists, it returns its display value.
• If not found, it returns a friendly message.

Step 3: Configure in UI Builder

Once the Data Broker is created:

1. Navigate to UI Builder.
2. Add a Data Resource using your new Data Broker.
3. Pass the property name dynamically or statically.
4. Bind the returned value to your component.
