Obtaining NVP/SOAP API Credentials

<< Immediate Payment

To make calls to PayPal NVP/SOAP API operations, you must have API credentials that identify you as a PayPal Business or Premier account holder who is authorized to perform API operations. While you can use either signature or certificate values for your authentication, PayPal recommends that you use certificate authentication for the best security.

To locate your existing NVP/SOAP API credentials or to create new credentials, see Creating and Managing NVP/SOAP API Credentials.
