How to send Winchill Part data to an ERP by API rest

Thank you for providing links and guides.
While some were already familiar to me, they weren't particularly helpful.
Recently, I discovered a POST command within the Swagger services of Windchill, which, instead of connecting externally, allows interaction within Windchill itself.
So i did some searchs and my discovery stemmed from a clue provided by ChatGPT.

My initial difficulty arose from the assumption that Windchill offered a direct POST service to interact with other APIs.
Adjusting my approach, I focused solely on finding a Java "send/post" command within Windchill to experiment with. After some searching, I found the following:

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/json");
connection.setDoOutput(true);

While I can generate XML if necessary, my current aim is to synchronize it with a JSON client's service.
Currently, I'm inquiring with my client about a testing environment to proceed with trials.

Once again, I appreciate everyone's assistance.
