Creating ECAD / EPM Documents in Windchill via REST API and describing the Part object with this doc

Version: Windchill 12.0

Use Case: My goal is to integrate Altium and Windchill. At the moment I am at initial stage. I have access to windchill test system. I have created sample parts and documents. Now I want to create ECAD document using REST API.

Description:

Hi everyone,

I'm working on integrating Altium with Windchill and am trying to create ECAD documents (EPM Documents) using the Windchill REST API. While I've successfully created parts and documents, I'm struggling to find a suitable endpoint for creating ECAD documents specifically.

I've explored the available endpoints and documentation but haven't found a direct way to achieve this. I'm wondering if anyone has experience with this or can point me in the right direction.

Any guidance, tips, or code examples, document would be greatly appreciated.

Thanks in advance!
