ReReplo is a powerful landing page builder, but its default "Add to Cart" behavior redirects to the Shopify cart page. This interrupts the intended Upcart experience, which uses a slide-out drawer.
With a simple JavaScript snippet, you can tell Replo to notify Upcart when a product is added, keeping the customer on the same page and opening the drawer immediately.
Why this integration matters
By default, Replo supports multiple post-cart behaviors:
Redirect to Shopify cart page
Redirect to checkout
Stay on the page (no drawer interaction)
Upcart doesn’t open automatically unless you explicitly trigger it. This setup ensures the drawer opens right after the Replo "Add to Cart" button is clicked.
Step 1: Open the product page in Replo
Open your product or landing page in the Replo editor
Select the Add to Cart button in the page layout
In the right-hand sidebar, click the Interactions tab
Step 2: Add a second interaction
Confirm that the button already uses the Add Product to Cart interaction
Click the
+icon under On ClickFrom the list of actions, select Run JavaScript
In the code input, paste the following:
javascriptCopyEditwindow.upcartRegisterAddToCart();
This tells Upcart to open the drawer as soon as the product is added to the cart.
Step 3: Disable Replo redirect to the cart page
Select the Add Product to Cart interaction again
Disable the Go to cart after? toggle
This prevents Replo from redirecting to the Shopify cart page, which would bypass the Upcart drawer entirely.
Step 4: Preview and publish
Click Preview in Replo to test the interaction
Add a product to the cart and confirm that the Upcart drawer opens automatically
Once confirmed, click Publish Page to push changes live
Notes
This setup must be applied to each page where you use Replo + Upcart together
The
javascriptCopyEditwindow.upcartRegisterAddToCart();function comes from Upcart’s public API and works without additional code installationsThis works for both mobile and desktop versions of Replo pages
Notes
Replo should now stop redirecting to the Shopify Cart Page and instead notify Upcart when an item is added to the cart.
Please note: you'll need to complete this process for each product page you design in Replo Landing Page Designer.
