I've previously accessed Salesforce reports programatically using a .NET webRequest to the following end point:
Including the user access token in the cookie.
I've since switched the organisation to use Lightning UI and ever since, the webrequest no longer returns the CSV instead it returns what looks like a new Salesforce intercepting page introduced with lightning (fireworks with the Salesforce logo).
Is there anyway around this intercepting page? Or any other way to access a report progrmatically?
