I need to get the full HTML of some news Page externally using CSOM or REST or something else. I know I have to create a CSOM app or something that will have to be register as an app on SPO.
What I cannot find is how to get the full page HTML so I can present it elsewhere. Maybe a simple http Get request. Is this possible?
I know there is a rest API that we can fetch CanvasContent1, but seems messy to parse it correctly and getting all the CSS to work correctly.
