Refer to the exhibit below.

The Additional Input property allows the developer to specify additional input parameters to be sent to the Integration Procedure element. The input parameters can be specified as a JSON object or as a list of key-value pairs. If the developer checked Send Only Additional Input, then only the input parameters specified in Additional Input are sent, and the SEND/RESPONSE TRANSFORMATIONS are ignored. Therefore, the developer needs to specify the same input parameters as in the SEND/RESPONSE TRANSFORMATIONS in Additional Input. Option C shows how to do this using a JSON object with two properties: “DBExtractAction:Account” and “DBExtractAction:SecondaryAccount”. The values of these properties are the same as in the SEND/RESPONSE TRANSFORMATIONS.
