I am trying to add modifier on a line item by POSTing on /v3/merchants/{mId}/orders/{orderId}/line_items/{lineItemId}/modifiers
and sending { "modifier": { "id": "[modifierId]" } }
But I don't understand from where to get the modifier ID?
Under "Inventory" -> "Modifier Groups", there is a table with list of group name and Modifiers. Group Name has for example "Protein" with ID "A4TZQAEN98DRE" and modifiers "Add Chicken" and "Add Bacon". How to setup/get IDs to modifiers i.e. "Add Chicken" and "Add Bacon" ?
If I use "Group Name" -> "Protein" ID then i am getting FileNotFoundException..
