Get Information on Updated Customers

This endpoint retrieves information on the customers which have been updated after the date passed into the query parameter LastCall, this accepts a date-time value. The query parameter batch can be used to pass an integer value that will be used as the maximum of customer objects to retrieve. A long with the customer objects this query also has the header X-Remaining-Customers which returns the number of customers which were not sent due to the batch size (e.g. If 500 customers were updated after the LastCall date and batch was set to 200. This header will have a value of 3000), if the batch is set to 0 or left null then all of the customers will be retrieved and therefore this header will have the value 0.
