To specify the custom details for a menu item selection, you add modifiers and pre-modifiers.
A modifier is a type of menu item that is configured as an optional component of another menu item. For example, sugar might be a modifier for a coffee menu item. For items that use size pricing, size is a modifier group.
A pre-modifier applies a text string to a modifier. It is typically
displayed before the modifier name on a Toast POS device display and in a
modifier description. For example, NO
and EXTRA
might be pre-modifiers for the sugar modifier.
In the orders API, to include the modifiers and pre-modifiers for a
menu item selection, you add a modifiers
value to the menu
item's Selection
object.
