After using the REST API for several days, I discovered an interesting structure in the database.

A drawing has a "References" endpoint, which allows me to find the assemblies or parts it references—this works without any issues. The link is even marked as a "Drawing reference."

However, even though the Windchill web interface has a "Referenced by" category, this category does not exist in the actual REST API.
