Pre-populating custom data
There may be times when you’d like to start setting up campaigns and segments using custom data before your development team has integrated that custom data. Braze allows you to pre-populate custom events and attributes on the dashboard before these pieces of data start tracking so that these events and attributes are available for use in dropdowns and as part of the campaign creation process.
To pre-populate custom events and attributes, navigate to the Manage Settings page and select the Custom Attributes or Custom Events tab. Then add a new custom attribute or custom event.
For custom attributes, select a data type for this attribute (for instance, boolean or string). An attribute’s data type will determine the segmentation filters available for that attribute.
Custom events and custom attributes are case-sensitive. Keep this in mind when your development team integrates these custom events or attributes later, they must name them exactly as you have named them here, or else Braze will generate a different custom event or attribute.
