Pre-Requisites

Prior to using the extension, ensure the following is in place:

A Visa Acceptance Solutions account with
Unified Checkout
enabled.
Payer Authentication direct connection if 3-D Secure is required.
A Token Management Service if you allow customers to save their payment cards on your website.

Contact support or your reseller if this needs enabling, or if you are unsure.

If you do not yet have a Visa Acceptance Solutions account, you can create one here. Demo accounts are created with United States dollars as the default currency.
