This might be a more generic web service consumption question, and not so much related to IFS specifically… Here is a thread on calling a SharePoint service from Oracle PL/SQL (with some good example code):

This is a link to the toolkit discussed in the above link:

Another thread on Oracle/SharePoint integration:
https://community.oracle.com/tech/developers/discussion/4212474/save-a-file-in-share-point
There does not seem to be a ton of information out there, and it is possible IFS has a better way via IFS Connect. Also, at least some of the SharePoint examples I found talk about using APEX, which I am not well versed in (and do not know if it is an option in IFS/Oracle).
The bottom line is that Oracle should be able to make web API calls, but there may be issues with authentication and request/response headers depending on the configuration of your SharePoint instance and Oracle installation.
Good luck,
Joe Kaufman
Thanks so much for sharing Joe, I’ll check those out! :)
