Create a checkout block
Checkout blocks add extra content and options to your checkout page, such as a free shipping progress bar or a way for customers to change their items. You create each block in the app, then add it to your checkout.
The blocks you can create
- Pre-purchase & upsell offers: show complementary products in the checkout to encourage customers to buy more. See Create an upsell offer.
- Discount Code Promotion: offer customers a discount to encourage them to complete their purchase.
- Free Shipping Progress Bar: show customers how far they are from unlocking free shipping.
- Age Verification: verify your customers' age before they can go on checking out.
- Line Item Modify: let customers change the variant and quantity of an item in the checkout.
- Contact Info: show your contact details in the checkout, so customers can contact you directly from there.
- Banner Image: show a static image in your checkout, based on custom conditions.
- Social Media Link & Icons: show social media icons in your checkout, based on custom conditions.
- Payment Icons: show payment icons in your checkout, based on custom conditions.
- Alert Box: show an alert text in your checkout, based on custom conditions.
Create a line item modify block
This example creates a Line Item Modify block, so customers can change the variant and quantity of an item, or remove it, right in the checkout.
-
In the app, go to Checkout Blocks and click Manage under Line Item Modify.

-
Click Create Block.

-
Enter a Title. Only you see it, not your customers.

-
Under Design Settings, enter the Modify Label Text and the Remove Label Text.
-
Tick what customers can do in the checkout: Allow customers to change a line item variant, Allow customers to change a line item quantity and Allow customers to remove a line item. Change the label text under each one if you like.

-
Under Advance Settings, choose when the block shows. See Choose when the block shows below.

-
Check the preview on the right, then click Save.

About the preview: the preview is a simulation. The real colors and fonts show in the live page. You can also open Preview in checkout editor, at the top right of the preview.
Choose when the block shows
Under Advance Settings, tick an option to limit when the block shows.
- Show only when specific products are in the cart: select the products. The block shows only when those products are in the cart.
- Minimal amount of products: enter a number. With 2, the block shows only when there are at least 2 products in the cart.
- Display only for a specific cart value: enter the minimum and maximum cart amount.
- Show only for specific countries: select the countries.
- Set start date and Set end date: show the block only for a specific period of time.
Keep in mind: a new block shows in your live checkout only after you add it in the checkout editor. See Show blocks and offers in your live checkout.
