According to the OmniScript Action Elements page, a DataRaptor Extract Action can be used to "get data from one or more Salesforce records" and an HTTP Action can be used to "get, save, or delete data through a web application programming interface (API)".

The correct syntax for merge codes in Integration Procedure is {(NodeName)}, where NodeName is the name of the JSON node in the data source. The other options are either missing the parentheses or using incorrect symbols.

The HTTP Action element in an Integration Procedure is used to make callouts to external REST APIs. It allows the developer to configure the endpoint, method, headers, and request body.

An Integration Procedure Action can execute an Integration Procedure that contains multiple elements, such as DataRaptor Actions, HTTP Actions, or other Integration Procedure Actions.
This can be used to save data to multiple systems, such as Salesforce and AWS Order Management, in one OmniScript element.

According to the Transform External Data Unit, the Expected Output JSON should match the Output Path of the DataRaptor Transform. In option D, the Output Path is Current:CityState, which matches the Expected Output JSON. The other options have different Output Paths that do not match the Expected Output JSON. Therefore, the correct answer is D.
