Default modifiers are able to be enabled on a per-location basis, depending on whether a location’s POS system supports this feature and the location wishes to utilize them.

A Default Modifier is a Modifier Item that should be considered as selected always unless the following condition should be met:

The Modifier Group that the Default Modifier belongs to has a Maximum Quantity of 1 set and another Modifier Item from the same Modifier Group has been selected explicitly.

When Default Modifiers have been enabled for a location, an additional default Boolean (i.e. true vs false) attribute will be applied to all Modifier objects in the Menu API response object. Default status will be communicated with a true value for default, and all instances where default status for a Modifier object is not applicable will have a false value for default.

In the below example, the “Choose Option (White Zuppa Di Mussels)” Modifier Group has 2 Modifier Items available, and the “Sweet” Modifier Item has the “default” attribute set to true. The Modifier Item that is not a default, has the “default” attribute set to false.
