The provided JSON structure shows that Customer is an array (indicated by []) containing a single object. In OmniScript, to access data from a specific index within an array, the pipe (|) notation followed by a zero-based index number (n) is used. Since the desired ID is in the first object of the Customer array, the correct index is 0. The correct path to the data is therefore Details:Customer|0:ID. Option A correctly implements this |0 notation. While %% delimiters are typically for OmniScript variables and not standard data JSON nodes in a Text Block (which usually use %), it is the only option that correctly identifies the array element's index.

B. To %%Details:Customer|n:ID%

This is incorrect because n is a placeholder for the index number; a specific integer like 0 must be used to retrieve data.

C. To %%Details:Customer|1:ID%

This is incorrect because arrays in OmniScript are zero-indexed. Using index 1 would attempt to access the second element, which does not exist in the provided data JSON.

D. To $Details:Customer|0:ID$

This is incorrect because $ is not a valid delimiter for merge codes in OmniScript. The standard delimiter is the percentage sign (%).

OmniStudio Documentation

"Access Data in an Array": This document specifies the syntax for accessing array elements. It states

"To access a specific node in an array

use the syntax ArrayName|n

where n is the array index number. For example

to access the first instance of an array

use ArrayName|0." This confirms that |0 is the correct notation for the first element.

OmniStudio Documentation

"OmniScript Merge Codes and Functions": This guide details the use of merge codes. It consistently shows the %datanode% syntax for pulling data from the data JSON into elements like Text Blocks. This confirms that % is the standard delimiter

and by extension

$ is incorrect.

3. Salesforce Help

OmniStudio Documentation

"OmniScript Text Block Element": The documentation for this specific element provides examples for displaying data: "Display data from the data JSON by using merge codes (for example

%FirstName%)." This reinforces that single % is the standard for this context.
