# Installing Upsell Extensions

Install and verify Shopify extensions for checkout, post-purchase, Thank You, and Order Status upsells.

# Before you begin

-   Shopify Plus is required for checkout app blocks and One-Click Upsell on production stores.
    
-   You need permission to edit and save the relevant Shopify checkout profile.
    
-   Create the strategy before testing its placement.
    

# Checkout Page extensions

In **Apps > Order Editing > Upsells**, open the setup action for the placement. In Shopify's Checkout Editor, add and save the matching block:

<table style="min-width: 50px;"><colgroup><col style="min-width: 25px;"><col style="min-width: 25px;"></colgroup><tbody><tr><th colspan="1" rowspan="1"><p>Placement</p></th><th colspan="1" rowspan="1"><p>Shopify app block</p></th></tr><tr><td colspan="1" rowspan="1"><p><strong>Product List Upsell</strong></p></td><td colspan="1" rowspan="1"><p><strong>Product List Upsell</strong></p></td></tr><tr><td colspan="1" rowspan="1"><p><strong>Checkbox Upsell</strong></p></td><td colspan="1" rowspan="1"><p><strong>Checkbox Upsell</strong></p></td></tr><tr><td colspan="1" rowspan="1"><p><strong>Free Shipping Upsell</strong></p></td><td colspan="1" rowspan="1"><p><strong>Upgrade to Free Shipping</strong> in the Delivery area</p></td></tr></tbody></table>

You can also add **Remove Product Upsells** to the order summary when customers should be able to remove an accepted Product List offer there. Checkbox Upsell already lets customers tick to add and untick to remove its product.

# One-Click Upsell

Open Shopify's checkout settings and select Order Editing as the post-purchase app. Only one app can own Shopify's post-purchase page. Save the setting, then return to Order Editing and check the placement status.

# Thank You and Order Status extensions

Use Shopify's Checkout Editor to add the main **Order Editing** block for product carousels. Standalone **Product List Upsell** and **Featured Product Upsell** placements need their own matching app blocks.

# Lock a strategy to one block

1.  Open the strategy.
    
2.  Enable **Only show this strategy when an app block requests it by ID**.
    
3.  Copy the strategy ID.
    
4.  Open the intended app block in Shopify's Checkout Editor.
    
5.  Paste the ID into **Locked Strategy** and save.
    

The locked strategy is excluded from normal matching and appears only when a supported block requests that ID.

# Recently Viewed needs a separate theme embed

The **Recently Viewed** product module also needs the **Order Editing - Pixel** app embed enabled and saved in your Shopify theme. A checkout app block does not replace that storefront embed.

After enabling it, return to the module and refresh its integration status. Check with a visitor who has viewed an eligible product; a visitor with no browsing history can correctly receive no Recently Viewed recommendation.

# Install a line-item highlight placement

Choose the intended highlight placement in the strategy, add at least one source under **What to highlight**, and save. Use that placement's setup action to add its matching app block in Shopify's editor. Confirm the page and position before saving the checkout configuration.

A product-offer block does not automatically install a highlight block. Check a qualifying item with the source data required by your highlight.

# Verify installation

Return to Order Editing and confirm the placement shows as installed. Use Shopify's Checkout Editor to verify block position and layout. For Checkout Page behaviour, add a product to the cart and continue to checkout without placing an order.
