The Retail Express Web Store API has been designed around the premise that the e-commerce web site will pull down all the
information needed from Retail Express in order to have a copy of all relevant data in its own database.
This structure allows the e-commerce site to function within itself until such point as information needs to be passed
back into Retail Express and updated within the e-commerce site.
The service has lockouts or throttling of one access per X Minutes for many methods.
Customers 60 Minutes - 1 Hour
Products 60 Minutes - 1 Hour
This is a restriction placed by Retail Express and while you may request temporary changes to this from the company it is only for emergencies or special cases like data migrations.
