Transformations can be mapped to sub-resources (children) of objects, but it is important to know that transformed sub-resources are not added to Swagger. To accomplish this task, you have to create a common resource and transformation to the sub-object within the root object. For example, in Connectwise CRM there is a sub-resource time-entries' within 'incidents' (e.g. /incidents/{id}/time-entries). Create a common resource that includes the fields you require, and then map a Connectwise Transformation to this resource for the 'incidentsTimeEntries' object.

Since this transformed sub-resource is not added to Swagger you will need to make API calls through GET /{objectName}/{id}/{childObjectName} where the objectName is the original resource and the childObjectName is the transformed sub-resource. Here is a Connectwise CRM example that shows mapping of the sub/child resource 'incidentsTimeEntries' to a common resource called 'myIncidentTime'.

With this transformation in mind and knowing that you are trying to reach the sub-resource/child object (in this example 'incidentsTimeEntries'), here is an example of how you must make the API call to:
