How to retrieve Primary End Item via REST API — full endpoint example?

Version: Windchill 13.0

Hi everyone, I found a reference in the ptc support explaining that it’s possible to retrieve Primary End Items in Windchill using REST API by filtering on WCTYPE|wt.pdmlink.PDMLinkProduct as typeId and selecting productReference. However, I’m not sure what the exact endpoint is to call in order to retrieve this data.

Could someone please share a concrete example of the full REST endpoint (including base path and entity name), ideally with $select or $expand usage if applicable? Thanks in advance for your help!
