Customize form controls

In this tutorial, you’ll learn how to do the following tasks:

• Retrieve a list of your store's checkout profile IDs
• Customize the label position and corner radius for all form controls
• Customize checkboxes to add a distinct corner radius
• Customize buttons to add inner padding and a distinct corner radius

• The store that you're modifying must be on a Shopify Plus plan.
• You've created a new development store with the Checkout and Customer Accounts Extensibility developer preview enabled.
• You've completed the GraphQL and REST Admin API getting started guide.
• You've either installed the GraphiQL app on your store or created an app, with the read_checkout_branding_settings and write_checkout_branding_settings access scopes.
• You're using API version 2023-10 or higher.
• You're familiar with the GraphQL Admin API's branding types.

Checkout styling properties apply to a checkout profile ID. In this step, you'll retrieve the checkout profile to which you'll apply form control changes.

1. Query checkoutProfiles to retrieve a list of checkout profile IDs.

   The is_published parameter indicates which checkout profile is currently applied to your store's live checkout.

2. Make note of your corresponding ID from the list. You'll supply the ID in subsequent mutations.

In this step, you'll set the label position and then the corner radius for form controls. For both styles, you'll use the checkoutBrandingUpsert mutation's customizations object and the CheckoutBrandingInput input object.

1. Set the label position.

   The following example puts labels outside fields. This keeps field labels visible when users are typing inputs, and improves accessibility.

2. Set the corner radius.

At this point, checkboxes have the corner radius that you set for form controls. However, this style makes the checkboxes look like radio buttons. In this step, you'll adjust the checkbox's corner radius to visually distinguish it as a checkbox and make its function clear.

The customizations for control don't apply to buttons. In this step, you'll style the corner radius and padding for primary buttons. For both styles, you'll use the checkoutBrandingUpsert mutation's customizations object and the CheckoutBrandingInput input object.

1. Set the corner radius.

   The following example shapes the buttons as rectangles with sharp corners, which affects the perceived clickability of the button.

2. Set the inline padding.

   The following example helps to ensure that the label doesn't touch the button edges, which improves readability and aesthetics.
