## Description

Retrieve items based on System Code
            
Items are a way of separating your tax calculation process from your tax configuration details.  If you choose, you
can provide `itemCode` values for each `CreateTransaction()` API call rather than specifying tax codes, parameters, descriptions,
and other data fields.  AvaTax will automatically look up each `itemCode` and apply the correct tax codes and parameters
from the item table instead.  This allows your CreateTransaction call to be as simple as possible, and your tax compliance
team can manage your item catalog and adjust the tax behavior of items without having to modify your software.
            
Search for specific objects by passing the `$filter` criteria in the body; full documentation is available on [Filtering in REST](http://developer.avalara.com/avatax/filtering-in-rest/) .
            
Paginate your results using the `$top`, `$skip`, and `$orderby` parameters.
