About Custom Properties
Custom properties enable you to supplement the standard properties of an item (such as name, description, and type) with more properties that are specifically applicable to your goal or organization. Custom properties can then be used for a variety of purposes, such as storing item-specific information and personalizing messages and creatives.
After you configure the custom properties, they appear in the Custom Properties section of an item’s Properties page. Custom properties are displayed in tabbed sections or collapsible sections, depending on the setting in your user preferences.
For planning items, you can configure custom properties to appear based on hierarchy or group settings. For more information, see Configuring Custom Properties.
To automatically populate the data values for custom properties from your external applications, you can create and configure custom connectors with endpoints for data integration. For more information, see Create a Custom Connector and Configure Endpoints .
