A DataRaptor Transform can simplify nested data by transforming it into a flat structure. The developer can use JSON paths to map the input data to the output data and define the output structure.

A Set Values Action in a Value field and a Remote Action in an Additional Output value field can execute a function like CONCAT or DATEDIFF by using the syntax {{function(parameters)}}. For example,
{{CONCAT('Hello', 'World')}} or {{DATEDIFF('2021-01-01', '2021-01-31')}}.

Using the LIMIT filter on the Extract definition allows the developer to specify the maximum number of results to return from the DataRaptor Extract. Defining a formula with the Filter function is used to filter the results based on a condition. Using a Custom Output Type when creating the DataRaptor is used to define the structure of the output data. Setting the Limit Property on the Action that calls the DataRaptor Extract has no effect on limiting the results.

According to Salesforce OmniStudio Integration Procedures documentation, when working with deeply nested JSON, Integration Procedures are ideal. They allow developers to flatten and manipulate JSON data, especially when handling external responses.
* C. Integration Procedure - This is correct. IPs provide Response Transformers, DataRaptor Transforms, and Response Actions to reshape and simplify nested data structures for consumption by front-end components.
Incorrect Options:
* A. DataRaptor Transform is used inside IPs but cannot directly handle external HTTP calls or manage complex orchestration.
* B. HTTP Action Element is used inside an Integration Procedure, but by itself, it does not process or simplify the data.
* D. Guided Workflow is not a recognized OmniStudio component for data transformation.

The correct answer is Option B, which shows a FlexCard with a header, a body, and a footer. The header contains the title and the icon of the FlexCard. The body contains a Data table element that displays the records from the parent FlexCard. The footer contains a navigation Action that invokes an OmniScript.
Option A is incorrect because it shows a FlexCard with only a header and a body, and no footer.
