If you would like to create a redeemable based on how many modifiers are available, you can add a Line Item Selector (LIS) with the following settings to the redeemable's Qualification Criteria.
Let's take for example a reward of a Free 2-Topping Pizza. We would like to apply the redeemable when a pizza has only 2 toppings, not less nor more. The menu item ID for a pizza is 202500, and the menu item ID for a pizza topping is 99999. In this example, we would create a Line Item Selector (LIS) like so:
- Add Base Item Attribute "Item Id", and select options "is" and "202500" (This option looks for the pizza menu item)
- Set Filter Item Set to "Only Modifiers" IF the redeemable should be applicable to the topping menu items of the pizza. Select "Base Item and Modifiers" IF the redeemable should apply to both the pizza and the toppings
- Under the Modifiers section, add the "Item Id" attribute with options "is" and "99999" (This option looks for the topping menu items)
- Under the Modifiers section, also add the "Quantity" attribute with options "is" and "2" (This option verifies that the redeemable works only when 2 toppings are present in the pizza)
