PayPal Name-Value Pair API Basics
Creating an NVP Request

5. Click Done to complete the process.
Creating an API Certificate
Create an API certificate only if your website requires it. Typically, you want to create an API
signature for your credentials instead.
If you do need a certificate, follow the instructions at
https://www.paypal.com/IntegrationCenter/ic_api-certificate.html.
NOTE: The certificate for API credentials is not the same as an SSL certificate for your
website; they are not related to each other.
Creating an NVP Request
The Name-Value Pair request format specifies the API operation to perform, credentials that
authorize PayPal to access your account, and fields containing additional information to be
used in the request.
