Finish setup
Enable the app embed in your active theme, then save.
Test cart syncing Check the customer cart on two devices.
- 1. Use two devices or separate browser profiles with empty carts. Sign in to the same Shopify customer account on both.
- 2. Add a product to the cart on one device.
- 3. Refresh the other device. The saved cart should open automatically when its current cart is empty.
Why am I asked to review my carts?
If you sign in with a separate cart that already has items or other cart details, CartThread lets you keep that cart, use your saved cart, or combine them. Items are only combined after you choose Combine carts.
If the carts use different countries, the review shows the current cart's country before combining. Shopify may change prices, discounts, or availability. If a change needs another review, follow the message and check the actual cart. You can keep shopping with your current cart or review the saved cart.
How long are carts saved?
Shopify expires unused or abandoned carts within 30 days of creation. This is not a guarantee that items will stay for a full 30 days.
With multiple carts, the saved name stays. If Shopify no longer has the cart, CartThread opens an empty replacement. Previous items are not restored.
