# System Properties

When updating an order, as well as the properties passed via the AddOrUpdateOrderProperty or AddOrUpdateOrderProperties methods properties collection as documented above, Tea Commerce will also add some system defined properties to the Order who's values will be automatically extracted. Details of these properties and how they are extracted can be found below.
