A Text Block element allows the developer to display read-only text in a table format, using merge codes to dynamically include data from the data JSON. A Rich Text Area element is used to display formatted text with images and links. A Text Area element is used to display editable text in a single line or multiple lines.
An Edit Block element is used to display editable fields in a form layout.

In OmniStudio Integration Procedures, when referencing data from a prior step in the HTTP Action URL, the correct merge code syntax is:
* %ElementName.PropertyName%
So, referencing a value called Date from a step named SetValues must be written as:
* %SetValues.Date%
This is the format recognized by the OmniStudio Merge Language (OML) for dynamic value substitution in URLs or headers.
Incorrect Options:
* A. Invalid syntax - not recognized by OmniStudio merge logic.
* B. {{SetValues.Date}} is used in FlexCards, not in Integration Procedures.
* D. %SetValues: Date% is incorrect merge syntax due to space and colon use.

A DataRaptor Load Action can be used to retrieve data from a Salesforce object by specifying the object name, fields, and filter criteria. A Lookup Input Element can be used to retrieve data from a Salesforce object by allowing the user to search for a record using a lookup field

Functions like CONCAT, DATEDIFF, and IF are supported in value fields where expressions can be parsed at runtime.
* B. In a Set Values Action in a Value field - Correct. The Set Values element supports expression functions in its Value field, allowing for real-time evaluation during IP execution.
* C. In a Data Mapper Action in an Input Parameters value field - Correct. Input Parameters to DataRaptors in Integration Procedures can use expression logic to dynamically compute and pass values.
Incorrect Options:
* A. Output JSON Path in DataRaptor is for structural mapping, not function execution.
* D. Remote Action Output fields typically receive data, not compute it.

The Add Response To Response JSON property on the DataRaptor Action indicates that the output of the DataRaptor should be added to the response JSON of the Integration Procedure. If this property is not set to true, the response will be empty even if the DataRaptor extracts data successfully.
