Developer previews

When a new feature is accompanied by a backwards-incompatible change to our APIs, or a significant change to the online store or Shopify admin, it is included in a developer preview. You can then test the feature by creating a new development store and enabling the developer preview from your Partner Dashboard.

Each developer preview can include several new features. When you enable a developer preview, you select the preview that includes the features that you want to have access to.

To learn more about development stores, their features and limitations, and how to enable a developer preview, refer to Create a development store.

For backwards-incompatible changes, the timeline for developer previews is tied to the API release schedule. When a stable version introduces a backwards-incompatible change, the feature associated with the change won't be available to a merchant's Shopify admin until 9 months later, when that version of the API is the oldest supported stable version. So you have 9 months to preview a feature and prepare for it before it is released to merchants. To learn more about the API release schedule, see Shopify API versioning.

The checkout UI extensions developer preview includes access to the following capabilities:

• Checkout UI extensions: Apps can integrate with Shopify checkout using these extensions to add custom UI and additional functionality to the checkout experience. For example, developers can build extensions that capture additional information from customers or show customers a recommended product offer. In the Shopify admin, you can use the checkout editor to place a checkout UI extension in the checkout experience.

• Tutorials: Code examples and instructions on how to build common use cases like adding a custom field to collect delivery instructions and product offers to checkout.

• Checkout branding: A set of resources on the GraphQL Admin API to apply styling to checkout like logos, colors, fonts, and more.

• Web pixels: A web pixel extension to build apps that enable merchants to track and send buyer behavioral data to a third-party service.

The documentation will be updated as Shopify introduces new extensions types for checkout.

• Shopify Functions: Shopify Functions enables you to extend or replace key parts of Shopify’s backend with custom logic. You use Shopify CLI to create, configure, and deploy a function to an app. In your function, you use Function APIs to extend your app code into Shopify.

• Discount combinations: You can add new discount combination settings to the Shopify admin so that merchants can combine discount types. The discount combination settings can be modified on the discount create and edit pages in the Shopify admin or through Function APIs.

The Duties and Taxes developer preview gives your development store the ability to charge duties calculated by Shopify during checkout, which avoids surprise charges for customers upon delivery.

Using the 2020-04 version or higher of our REST or GraphQL Admin APIs, you can fetch duty amounts charged on international orders through checkout. Using the GraphQL Admin API, you can create refunds that include the duty on an entire order or individual line items.

Refer to our guide on how to use duties using the GraphQL API.
