Objective: Use Google Reader to subscribe to a Basecamp RSS feed.
Problem: Google Reader doesn’t support RSS authentication.
Solution: Use Yahoo! Pipes to authenticate & deliver the feed to Google.
1. Create a new pipe or clone this existing one: http://j.mp/PipesToReader
2. Enter your username, password, and URL [note the devil is in the details]
To locate your username & password, go to ‘My Profile’ in Basecamp. Scroll to the bottom and click ‘Show Your Tokens’ in the ‘Authentication tokens’ section. Copy the value of ‘Token for feed readers or the Basecamp API’ and use this as BOTH your username and password.
From the Basecamp overview page, click ‘Project RSS feed’ copy the URL listed below ‘Your RSS feed URL.’ Remove the preceding ‘https://’ from the URL prior to pasting it into the pipe URL.
3. Click ‘Run Pipe’ this should authenticate and display the feed.
4. Click the ‘Get a RSS’ icon and then copy and paste this URL into google reader.
Security Note: Make sure you DO NOT have your Google Reader feed shared. If your feed is shared it will be accessible to the world and your API username / password will not be protected.
