Unfortunately, HUE Free Gift Upsell does not fully support third-party side cart or sticky cart apps.
However, you can use our own side cart solution:

HUE Cart Drawer

HUE Cart Drawer is fully compatible with HUE Free Gift Upsell and supports displaying widgets directly inside the cart drawer.

Why HUE Free Gift Upsell doesn’t support other side cart drawers

Most third-party side cart apps fully control:

• Cart drawer structure
• Add to cart flow
• Checkout actions

Because of this, there can be limitations with:

• Discount display
• Widget placement
• Offer triggering
• Checkout discount handling
