Below is the raw code to make a Google App Engine application with the really basic bit.ly api. Theres currently no error checking etc.

If you just want the functionality use the BitLy class in your App Engine code. Currently is just returns simple for you to use. So for example with shorten to access the the hash you would use: json['results'][urlentered]['hash']. Replace the url entered with the url you supplied.

Any questions please email ch at chrishannam dot co dot uk
