Performance Considerations

The best customer experience will result from the fewest API calls possible. It is your responsibility to optimize your checkout code to reduce API calls. If you are lazy in your programming your checkout requires additional optimization then you will have two choices. Either implement the required suggestions made by UC Pro Services or utilize the premium support of UC Pro Services to have them implemented for you. Having a poorly written custom checkout that places unnecessary load on the UltraCart system will not be tolerated. You will have your ability to use the javascript checkout API removed if you do not follow the rules.
