I know how to upload files to SharePoint programmatically from CSOM but I need to do it from an application that I can’t modify, this application only gives me the option of establishing a url where it sends the file, what url can I use? What code can I use in that url to deal with the file sent?
The application sends a xml file any time a survey is filled to a url, I want to include that xml file in a library and process the xml.
