To pass all records from a parent FlexCard to a child FlexCard, the developer must reference the entire data node from the parent's data source. By default, or by convention, the array of records returned from a data source (like a DataRaptor) is stored in a node named Records. The syntax {Records} is the correct Merge Field notation to pass this entire array to the child FlexCard, which can then use it to populate its Datatable. This ensures the child has access to the complete dataset from its parent as required.

OmniStudio Documentation

"Pass Data Between a Parent and Child FlexCard": This official guide explicitly states

"To pass all the data from the parent FlexCard's data source to the child FlexCard

enter the name of the parent's data source JSON node in the Node field. For example

if the parent's data source is a DataRaptor that returns a node called 'Accounts

' enter {Accounts}." This directly validates the use of {Records} when the node is named Records.

OmniStudio Documentation

"FlexCards Data JSON": This document illustrates the structure of data within a FlexCard. It shows that a data source action populates a top-level node (e.g.

Records

Contacts) which contains an array of objects. To access the entire array

one must reference this top-level node.

3. Salesforce Trailhead

"FlexCard Basics" Module

"Display Data on a FlexCard" Unit: The training materials demonstrate that to iterate over a list of records or pass it to another element

you reference the array node directly

such as {records}. This reinforces the principle of using the node name in curly braces to access the entire dataset.
