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
an 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 this key is a P12
certificate. For more details, see Create a P12 Certificate.
