Ultra Cart - For Merchants, By Merchants

Advanced Integration

UltraCart has hundreds of advanced features available, but even we can't predict every need.  If you require additional functionality not integrated directly into the UltraCart E-Commerce Platform, you can use our available advanced integration interfaces to offer complex and robust services to your website visitors.

  • Activation Codes

    Selling software that requires a custom registration code?  Or need to provide a user name & password in real time?  Check out our Activation API to see how you can utlize UltraCart in these scenarios.
  • API

    The UltraCart API provides developers with a number of advanced tools to programmatically manage their UltraCart account. These APIs can be used to dynamically update item inventories, query a customer's cart contents, and more!
  • XML Postback

    Allows your server to receive XML notifications when orders are placed or changed. This is a great way for merchant to integrate in house applications.
