PayPal NVP API Overview
Posting Using HTTPS
18 08 April 2009 Name-Value Pair API Developer Guide
Posting Using HTTPS
Your web application posts the URL-encoded NVP string over an HTTPS connection to one of
the PayPal API servers. PayPal provides a live server and a Sandbox server that allows you to
process transactions in a test environment.
API Servers for API Signature Security
If you use an API signature, post the request to one of these servers:
Sandbox: https://api-3t.sandbox.paypal.com/nvp
Live: https://api-3t.paypal.com/nvp
API Servers for API Certificate Security
If you use an API certificate, post the request to one of these servers:
Sandbox: https://api.sandbox.paypal.com/nvp
Live: https://api.paypal.com/nvp
