How do I turn on the app embed in my theme?

Updated November 2, 2026 · SMART Bundles App & Upsells (E-TRADE PARTNER)

In the app's Home, click Turn on app embed. Your theme editor opens on App embeds with Deal widget (listed under the app name SMART Discounts) switched on. Click Save there, and Home shows App embed as Active.

Why the app embed is needed

The app embed is how SMART Bundles reaches your storefront. Without it, no bundle widget shows on your product pages and a Free gift can't add its gift to the cart. It loads the bundle widget's script only while you have a live bundle, and the free gift script only while a Free gift is live.

The other discount types (Volume discount, Order goal, Buy X get Y, Shipping discount and Advanced discount) apply in the cart and at checkout and don't need the embed.

Turn it on from the app

1. In your Shopify admin, open Apps and choose SMART Discounts. That is the name SMART Bundles App & Upsells has in your admin.
2. On Home, find the App embed card at the top. While it says Inactive, click Turn on app embed. The setup guide on Home has the same button under Turn on the app embed in your theme.
3. The theme editor of your published theme opens in a new tab, on App embeds, with Deal widget turned on.
4. Click Save in the theme editor. The embed isn't live until the theme is saved.
5. Go back to the app tab. Home checks again every few seconds and switches the card to Active on its own.

You also get this step when you create a bundle or a Free gift while the embed is off. The dialog Turn on the app embed in your theme offers Turn on app embed or Continue without it, so you can set up the offer first and turn the embed on later.

Turn it on by hand

These are Shopify's own steps for app embeds (Shopify Help Center):

1. In your Shopify admin, go to Online Store.
2. Find the theme you want to edit and click Edit theme.
3. In the sidebar, click the App embeds icon.
4. Turn on the toggle next to Deal widget (SMART Discounts).
5. Click Save.

Limits and edge cases

• Published theme only. The App embed status on Home reads your published theme. Turning the embed on in a theme you haven't published doesn't change the status, and shoppers only see the published theme anyway.
• Changing themes. Shopify says apps aren't active by default in a newly published theme. After you publish a different theme, turn Deal widget on in it and save (Shopify Help Center).
• No theme code edits. Shopify says app embeds work with any theme version. SMART Bundles only reads your theme; it never edits theme files.
• Nothing to set in the embed. Deal widget has no settings in the theme editor. Where the widget sits is set in the app: see Place the bundle widget.
• The embed alone shows nothing. A product needs an active bundle that targets it. Start with Create your first bundle. If a bundle still doesn't show, work through Bundle widget not showing.
• Stuck? While the embed is inactive, the App embed card on Home has a Need help? button that opens support.
