For Developers Only
To help system integrators assess whether to update the data in their own systems, we've added a LastModified date and timestamp to our API calls.
For instance, in the Customer/All endpoint, the API will return customers who had any kind of activity over the time period requested. That might include a purchase, refund, or update of their customer info. Along with their current set of info and items, the API will provide the LastModified timestamp:

If the timestamp isn't more recent than the last update in whatever external data the integrator is using, this update can be ignored.
