Use these pages to help you test API calls to PayPal.  The menu is broken down by Classic API's, Platform API's, REST API's, and Payflow API's.  I hope to keep adding new API's to these test pages, but these are the main ones that are used.  They should be enough to get you started testing with.  Please submit any feedback or questions that you may and I will try to response to you as soon as possible.
