Stencil and App Compatibility

With our new Stencil themes, certain apps may have extra steps to make them compatible with the theme.  Apps that handle backend store functions such as shipping and inventory management are all supported regardless of the theme platform. Apps like Quickbooks Online and Shipper HQ work natively with Stencil.

For apps that require an additional script, there is a small possibility it will not work with a Stencil theme without customization. The apps listed here have been tested and confirmed to work with Stencil themes, but this is not a comprehensive list of all apps that work with Stencil.


All new apps are required to work with Stencil. Almost all apps currently available in the app marketplace work with Stencil. There are only a small handful that may not have updated their code yet or need a few extra steps to work.

If any app does require scripts to be placed in the storefront theme, instructions should be included during setup. If Stencil-specific instructions are not provided, use the suggestions below for best practice placement. Questions regarding an app’s instructions should be directed to the partner who supplies the app.

Apps That Work with the Script Box

Apps that affect the storefront — such as a live chat box or coupon code pop-up — may have some extra steps to make them work. If the app requires script or code to be pasted into the site’s footer or header, it is possible to use them by going to Storefront Design › Design Options Scripts tab.

Scripts tab in Design Options

These apps work with Stencil if you paste the code into the Script box:

  • JustUno
  • InStockNotify
  • McAfee Secure
  • Olark
  • Picreel Exit Offer
  • YotPo Reviews
  • Sweet Tooth
  • S Loyalty

If the app requires code to be pasted into the HTML head, you can do that by going to Advanced Settings › Web Analytics Google Analytics tab.

Apps That Need an Edited Theme

If the app’s code does not work when put into the Script box or Google Analytics tab, it may require that the script be pasted onto a specific page. These pages are accessible with Editing Stencil Theme Files.

The apps listed here will work by editing a Stencil theme:

  • Listrak Retail Solutions
  • Nextopia

We recommend working with one of our Partner Services if you are unfamiliar with web development.
