Flexcards use merge fields to display data from a connected JSON data source. These fields use curly braces to bind UI elements to specific nodes within that JSON structure.

Core information

Merge fields reference data nodes using the {field name} format within Text or Field elements.

More details and nuances

Integration Procedures use percent signs %...% for merge fields, which differs from the curly braces {...} used in Flexcards.
