Detect discount by ID in the order (API and Webhook)

[its-anas]

We can only identify the discount with its title but not an ID, and discounts can have the same title so we are unable to identify it.

Hey Anas 👋🏻 Not sure I follow- what API are you referring to and how does this relate to functions?

Hi @DuncanUszkay1
I was referring to Order API. In the discount applications part you get something like this:

"discount_applications": [
{
"type": "manual",
"title": "custom discount",
"description": "customer deserved it",
"value": "2.0",
"value_type": "fixed_amount",
"allocation_method": "across",
"target_selection": "explicit",
"target_type": "line_item"
},
{
"type": "script",
"description": "my scripted discount",
"value": "5.0",
"value_type": "fixed_amount",
"allocation_method": "across",
"target_selection": "explicit",
"target_type": "shipping_line"
},
{
"type": "discount_code",
"code": "SUMMERSALE",
"value": "10.0",
"value_type": "fixed_amount",
"allocation_method": "across",
"target_selection": "all",
"target_type": "line_item"
}

Assume you are creating an automatic discount using shopify functions, and after sale you want to check if a discount was applied to some line item in an order. There is no way to identify the discount with something other than the title (which is not unique i believe, because you can return any title on the function output), so getting the ID will help in identifying the discount and use it in query.

This would be a great addition, because it would allow app developers to bill based on # of discount applications, in a foolproof way.

It would also allow:

• Tagging orders where specific discounts applied
• Reporting total sales amounts when discounts were used
