I'm using the omniauth gem for Railshttps://github.com/asanghi/omniauth-constantcontact2 and my app seems to be going to Constant Contact correctly via "Grant Access" but then it explodes with a very unhelpful "Invalid redirect" error.
My callback uri for my app is http://localhost:3000/auth/constantcontact/callback with is following the convention of integration with five other apis that are working fine. Any ideas why it doesn't like my callback? The error doesn't even tell me what uri I am trying to use. That would be very helpful information for that error.
The earlier omniauth-constantcontact gem just gave me NullPointerExceptions. It might be worth investing in something to track exceptions like New Relic.
