Generating a P12 Certificate

You can use this validation product only through a REST API integration.
You must create a
REST
key for your merchant ID. If you already have a
REST
key for other
Cybersource
REST
services with the same merchant ID, you can use that key to access the Visa Bank Account Validation Service. Ensure that the key is a P12 certificate. For more details, see Create a P12 Certificate.
