How to enable Shopify Plus checkout.liquid customizations
Requirements
If you want to customize your checkout, you’ll need two things:
- Be on a Shopify Plus plan
- Enable access to your checkout.liquid theme file
The second step is an important one. Without enabling access to checkout.liquid, you can't customize it.
To check if you have access, go to your Online Store > Themes > Actions > Edit code > Layout > confirm you can see the checkout.liquid file.
If you don’t see the checkout.liquid file, click ‘Add a new layout’ > select ‘Checkout’ and give it a name > Create layout.
If you click ‘Add a new layout’ and don't see an option to add 'Checkout', this means you don't have access yet.
Requesting access
Shopify usually does this within 36h.
Once the customization is enabled, you can go to the Settings tab in the app and choose 'Checkout.liquid offer position'. Choose a position and click 'Save'. Now the upsell will appear in your checkout.
Go ahead and check it in incognito mode to see the result!
