Chris Saunders commented on GET orders by date range

Could you provide an example of what you mean?

If you only wanted orders between Jan 1 and Jan 15 2014 you could make a query like this:

https://shop.myshopify.com/admin/orders.json?created_at_min=2014-01-01&created_at_max=2014-01-15

You can find other filters you can apply to your GET requests on the Orders API documentation
