How to turn on an app embed in your Shopify theme
You turn on an app embed in the Shopify theme editor: open Online Store, then Themes, choose Customize on your published theme, open App embeds in the left sidebar, switch the app on and save.
Steps
- In your Shopify admin, go to Online Store and then Themes.
- Next to your published theme, click Customize.
- In the left sidebar, click the App embeds icon.
- Find the app and switch its toggle on.
- Click Save.
Why an app embed is off
App embeds are inactive until you turn them on. Many apps send you to the theme editor with the embed already selected, but nothing is active until you save.
App embeds are set per theme. Script tags loaded on every theme; an app embed only runs on the theme where it is switched on. After you publish a new theme, check App embeds again.
When there is no app embed to turn on
If an app does not appear under App embeds, it may still load through a script tag, add a block you place in a section instead, or not need anything on the storefront. Apps that still rely on a script tag need an update from their developer before 1 March 2027.
