Which of the following is a valid merge field for a JSON sub node in OmniScript?

• A. %node|1:object%
• B. %node|1:string%
• C. %node|1:array%
• D. %node|2:array%

Answer: (C)

When working with a JSON payload in OmniScript, you reference a sub node using a merge field that specifies the node index and the data type of that sub node. If the sub node contains multiple items, you indicate that by using the array type in the merge field, which tells OmniScript to treat the referenced portion as a collection you can iterate over or access items from.

In this case, the sub node at the first position is an array, so the valid merge field is the one that uses the array type for that index. This ensures OmniScript handles the sub node as a list of items rather than a single object or scalar value. Using object would imply a single JSON object, and string would imply a simple value, neither of which matches an array. Referencing a different index (for example, the second sub node) would only be correct if that specific sub node were the array you intend to work with.
