I was looking for ways to integrate Thingworx with Sharepoint. Use case is to get Images, data in excel from sharepoint and display on Thingworx mashup.
I tried WebFrame widget, it says: ptccloud.sharepoint.com refused to connect, but you can use a Link widget in the mashup, and upon click a new browser page will be opened.
If you have TWX Flow, you can work with Excel online, Office365, Azure and other softwares. It helps thingworx interact with other tools, but it also does not support TWX showing other pages.
PS : TWX mashup can present PDF file
