Processes an order automatically. The customer does not need to use a browser, interact with Cleverbridge, or enter new payment information. Instead, Cleverbridge uses the customer's most recent payment details to process the order. If the order cannot be processed automatically, the API returns a unique URL that can be sent to the customer in order to complete their transaction on the Cleverbridge-hosted page. To process an order, you have to submit a customer identifier and the cart item(s). The customer identifier can be a former purchase ID of an existing customer with Cleverbridge (LogonPurchaseId), your own client account identifier (CustomerReferenceId), or a subscription ID (SubscriptionId).
