Discount extention targeting cart.lines.discounts.generate.run not showing up in Admin -> Discounts -> Create

Functions
1

Hi,

I just finished working on a discount function using the examples at Build a discounts UI with Remix however with the new 2025-04 API’s the examples here are now outdated. When I create a new extension with the shopify CLI targeting discount

{F45F70DF-1005-4A66-945A-F55AE7248ABD}
{F45F70DF-1005-4A66-945A-F55AE7248ABD}544×375 22.7 KB

this doesn’t show up in the admin create discount UI even though the function record exists when I search via graphql. I assume I’m missing something, but the docs arent super clear on where I should be looking.

{
	"app": {
		"title": "title",
		"handle": "my-apps-handle"
	},
	"apiType": "discount",
	"title": "Customer Discount",
	"id": "----",
	"useCreationUi": true
}

TOML for reference

api_version = "2025-04"

[[extensions]]
name = "t:name"
handle = "customer-discount"
type = "function"

description = "t:description"

[[extensions.targeting]]
target = "cart.lines.discounts.generate.run"
input_query = "src/generate_cart_run.graphql"
export = "generate-cart-run"

[extensions.build]
command = ""
path = "dist/function.wasm"

[extensions.ui.paths]
create = "/app/customer-discount/:functionId"
details = "/app/customer-discount/:functionId/:id"

I have the same issue.

The guide for discount functions is using the deprecated product discount instead of the Discount API:
Build a product discount function

And when using the guide for Discount UI using Remix: Build a discounts UI with Remix
The app/discount function does not show.

Hey folks - thanks for flagging that these docs could be out of date, connecting with the relevant team to update these.

Hey @Liam-Shopify Thank you, let us know when it is updated!
Can you let us know in the meantime what we can do to have the discount function option showing in the admin => Create discount with that new API?
