THIS PROJECT IS NOW DEPRECATED

This project is deprecated and will be removed in the near future. Delete your fork of this project and watch/fork PayPal APIs Up and Running instead. Appendix A provides a cleaner baseline Tweet Relevance project and each chapter integrates a different PayPal product with it.

Overview

This GAE project provides sample code that demonstrates how to create a minimal web app that logins users with their Twitter account and displays only their most relevant tweets (as determined by a trivial algorithm that can easily be modified/extended) as part of a UX that is optimized for a mobile client. First-time visitors get to login free for a number of times and experience the app before they are requested to purchase additional logins to continue using the app.

Mike Knapp's https://github.com/mikeknapp/AppEngine-OAuth-Library project is used to handle making OAuth requests to Twitter.

Pat Coll's https://github.com/patcoll/paypal-python project is adapted to implement a (Mobile) Express Checkout flow using PayPal

The application's primary UI is adapted from the final installment of SitePen's TweetView project at http://dojotoolkit.org/documentation/tutorials/1.6/mobile/tweetview/packaging/ and is intended to be delivered to a mobile display like an iPhone, although development works fine on a desktop browser like WebKit. The UI for the payflows is minimal.
