+In this example, we're making a POST request to an IPAM system with no payload.
+
+Some ingredients are required to perform the query, in this case, $prefixId. Hence It is provided as an input-key-mapping and defined as a key-dependencies. Please refer to the modeling guideline for more in depth understanding.

+To tell the resolution framework what is of interest in the response, the output-key-mapping section is used. The process will map the output-key-mapping to the defined data-type.
