When creating a registration page with the API, are we able to bypass the shopping cart?

Yes, the Purchase command enables direct real-time purchases without using a Shopping cart and the associated queuing delay. The Purchase command is typically used for a single-name purchase and returns an immediate success/failure response. Most commonly, the Purchase command is used by resellers who maintain their own databases.

The following is an example query that requests the purchase of domain name partnerdomain2.net, and requests the response in XML format:
