When you have created a mapping in the inbound content mapper, the mapping gets an id. To apply that mapping when you use the migration center's /content/source endpoint you must supply the mapping id. In this scenario, you should have the mapping id as a data point that is returned to you when you then check up on the content using the /report/detail endpoint.
I would expect to see this value at the top level of the return payload, alighned with where the groupId, ansContent, ansType, ansId values are, or at the very least for the sourceAdditionalProperties field to be returned if it was sent.

Hi, this information is currently returned on the report/details endpoint if you add the following query param: documentType=source OR documentType=all
