Custom Buttons
Add action buttons at checkout β call, email, or open links. Custom Buttons let buyers reach support, read FAQs, or contact your team without leaving the checkout flow.
Requires Shopify Plus. Custom Buttons uses Checkout UI Extensions, which are available on Shopify Plus plans.
What it does
Custom Buttons displays a group of action buttons at your Shopify checkout. Each button can:
Click to call β tap to dial a phone number directly
Open link β open a URL in a new tab (FAQ page, policy page, chat link)
Send email β open the email client with a pre-filled address
Buttons support multiple visual styles (Primary/Secondary), icons from 49 built-in Shopify icons, and horizontal or vertical layouts. Each button group gets a unique Widget ID for placement in the Theme Editor.
Step 1: Go to Extra Widgets
In the app sidebar, click Extra widget. Find the Custom Buttons card and click Manage.
Step 2: List page overview
The list page shows all your custom button configs.

Step 6: Add the block in Theme Editor
After saving your button config in the app, add it to your checkout page:
Go to Shopify Admin β Online Store β Customize
Navigate to the Checkout page in the theme editor
Click Add block β select AOV Custom Buttons
In the block settings, enter the Widget ID you copied from the app
Position the block where you want it (main content area or Order Summary sidebar)
Click Save in the theme editor
You can add multiple Custom Buttons blocks β each with a different Widget ID β to display different button groups at different positions.
If the Widget ID is invalid or doesn't match any config, the block will be hidden at checkout β it won't break the checkout page.

Tips
Use Primary for the main action β "Call Us" or "Get Help" should stand out with the blue Primary style
Use Secondary for supporting actions β "FAQ", "Shipping Policy" work well as Secondary buttons
Keep labels short β under 15 characters for horizontal layout, under 20 for vertical
Max 3 buttons horizontal β more than 3 becomes too cramped, switch to vertical
Use Vertical layout in sidebar β the Order Summary column is narrow (~380px), horizontal buttons get squeezed
Add icons for visual clarity β "Text with Icon" buttons are more scannable than text-only
Use "Click to call" for mobile buyers β phone buttons are especially effective on mobile checkout
Test on mobile β verify button layout looks good on smaller screens
