Allow customers to access your loyalty program by adding a loyalty widget to your BigCommerce store.

June 14, 2025

For BigCommerce users

⚠️ Important: This widget is no longer supported. All Marsello accounts are being migrated to the new Customer Portal. Learn more about the new Customer Portal here.

Before you get started

Here are some key details to note before adding a loyalty widget to your BigCommerce store:

  • The loyalty widget is added to your store differently, depending on whether your store is using a Stencil theme or a Blueprint theme.

  • ️️Stores using the Stencil theme will have the loyalty widget installed automatically when the Marsello app is installed.

  • Stores using the Blueprint theme will have to follow this guide to install the loyalty widget.

Find which BigCommerce theme platform your store uses

A quick way to tell what theme platform you currently have applied to your storefront is to go to the Storefront menu in the control panel.

Stencil

  • If the Storefront menu shows Footer Scripts as an option, you are using a Stencil Theme.

Blueprint

  • If the Storefront menu shows the Mobile Theme Settings, you are using a Blueprint theme.
