I am attempting to create an extension which will connect to the SharePoint REST API, however I need get the NTLM authorization header.
I can authenticate fine through the data load editor, but am struggling to be able to create the NTLM header through the extension due to cross origin resource sharing (CORS) issues, and I cannot change these settings on the SharePoint server.
My thinking is that if the REST data connector can succesfully connect, I should be able to replicate this in an extension.
Has anyone come upon this and found a solution?
