### Joy and Swish (Wishlist King)
Joy automatically detects Swish — the wishlist app formerly known as Wishlist King — and surfaces the customer's wishlist right inside the Joy on-site widget.

### How the integration helps

- No manual setup: Joy detects Swish's SDK on your storefront and connects automatically
- Customers view their Swish wishlist without leaving the Joy widget
- Guest wishlists are supported, not just logged-in customers
- Add/remove actions sync back into the Joy widget in real time

### How the integration works
Joy reads Swish's `window.WishlistKing` SDK to pull the customer's saved items and renders them using the same product-card UI as the rest of the Joy widget. Wishlist mutations go through Swish's own SDK, which keeps both experiences in sync.
