This extension allows users to pay for their orders using the Opayo payment gateway.
The Opayo payment gateway communicates with the user's browser using a secure protocol.

Once the user completes their transaction (pays successfully or fails for any reason), Opayo redirects the user's browser back to the deployment which processes the result in a custom page.

The page shows more details if the payment fails for any reason (i.e. the user times out or cancels payment), then redirects the user to the order list.

The extension supports deployments with multiple currencies and supports the Payment, Deferred and Authenticate transaction types (see Setting Up for more details).

Opayo was formerly known as SagePay.
