Discount apps can now register with Sidekick: what sellers check

For a store running buy-2-get-1 or tiered deals, the update helps only if its discount app has registered the new intent, and flows that open the app's own page currently work only in Shopify admin on the web. The update covers creating the offer; shoppers see the deal only where the product page and cart show it. No public data ties Sidekick-built offers to sales.

Considering the Sidekick placement, are merchants going to expect that Sidekick works with every app?

I hope @Shopify is already committed and working on improving the poor UI + UX this new dashboard introduced. https://t.co/VLK5zl92uA

• September 28, eligibility: Shopify's changelog said Sidekick now surfaces app extensions that declare only intents, with no tools file (shopify.dev). An intent is an action an app registers, such as creating a discount, that Sidekick can hand off to that app. The change applies to all apps on all stores, with nothing to opt into.

• September 30, discounts: Apps that create new discount types with Shopify Functions (Shopify's system for custom discount logic) can now register shopify/Discount intents. Sidekick can then launch the app's create and edit flows and promote them in what Shopify calls the disambiguation picker, where Sidekick offers options to choose from (shopify.dev).

• Why it is being discussed: At least one discount app was pitching a Sidekick workflow before the changelog. @bogo_freegift, the account of the BOGOS app, said in a September 21 post that its team presented a ShopX 2026 Buildathon workflow turning customer data into live personalized offers in 15 minutes with Sidekick and BOGOS (post). App developer @junaidkbr asked whether merchants will expect Sidekick to work with every app (post).

• What the changelogs leave out: Both entries cover the admin side, while two recent seller posts point at the cart. @EcomKostnchko_ asked for a BOGO app that automatically doubles quantity in the cart slider and can be switched on for promo days (post). @b_szafranow said an automated test of their test store's cart page flagged a missing discount line and a subtotal of $80.10 instead of $89 (post).

• What to do now: Ask the developer of your discount or bundle app whether it has registered shopify/Discount intents, and try the flow from Shopify admin on the web. Before a promo goes live, check that the offer shows on the product page and as its own line in the cart with the right subtotal, the failure @b_szafranow's test caught.

Does Sidekick now work with every discount app?

No. Shopify's September 30 entry covers apps that create discount types with Shopify Functions and register a shopify/Discount intent, and it says Discounts UI extensions on the admin.discount-details.function-settings.render target are promoted automatically (shopify.dev). We could not find a public list of BOGO, bundle or tiered-discount apps that have registered, so the app's developer is the one to ask.

Can I use these app flows from the Shopify mobile app?

Not fully yet. Shopify's changelog says link-based discount flows are currently supported in Shopify admin on the web; those discounts can appear in the mobile app's discount list, but tapping one does not open the app's edit flow (shopify.dev).

Where does a buy-2-get-1 offer need to show up once it exists?

On the product page and in the cart, with the same tiers and prices. Two DTC page designers who sell redesign services show one way to do it: @johntech778 puts a Buy 1 Get 1 Free banner above the logo of a supplement page (post), and @williamdtc2y lays out 1 pack, 2 + 1 and 3 + 2 options so shoppers don't have to do the math (post).

A discount does not always come with a matching label on the page: a merchant on the Shopify Community asked how to show a "SAVE $5" or "15% OFF" badge on Horizon theme product pages after trying a few standard code snippets (thread).

Is there evidence that Sidekick-built offers sell more?

Not publicly. The 15-minute figure from @bogo_freegift describes setup time in a demo by the app's own team, and neither Shopify changelog reports order or conversion data.
