Hi, To address your questions:
a) Auth tokens expire after 2 weeks, or when a user changes the password on their account. b) The reason returned for an expired auth token is LOGIN_COOKIE_INVALID, which isn't immediately obvious. We are working on improving the documentation to make this more clear.
