How to Create, Update, and Link WTDocument to WTPart using Windchill OData REST Services?

[ozclkonur]

Hello,

I am working on an integration project and I need to perform the following actions using Windchill OData REST APIs:

1. Create a new WTDocument.

2. Update attribute values (IBA/Soft Attributes) of existing WTDocuments.

3. Link (Associate) the created WTDocument to an existing WTPart (e.g., as a Described By or Reference link).

Could you please guide me on which standard Domains (e.g., ProdMgmt) and Endpoints I should use for these specific operations? Is it possible to achieve the linking process within the same transaction or does it require a separate API call?

Any examples or documentation references would be appreciated.

Best regards.

for the links ; 

this a known gap addressed 13.0.2.7 and 13.1 where the endpoint is added OOTB:

For older release, we can use a custom endpoint as described in article https://www.ptc.com/en/support/article/CS285572

Attached is a demo video from my local 12.0.2.3  .
