Creating an API Certificate
Create an API certificate only if your website requires it. Typically, you want to create an API

NOTE: The certificate for API credentials is not the same as an SSL certificate for your

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.
