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 the Shopify admin, it's included in a developer preview.

You can 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.

A development store with a developer preview enabled includes all of the features that are available on the Advanced Shopify plan, but the store can't be transferred to another owner or transitioned to a paid plan. To learn more about development stores and their features and limitations, refer to Development stores.

1. From your Partner Dashboard, click Stores.
2. Click Add store > Create development store.
3. In the Development store use section, select Create a store to test and build.

4. In the Store details section, enter a name for your store.

   The store name is used to create the store's myshopify.com URL. This URL can't be changed.

5. Choose the build that you want to use.

   If you select a Developer preview, then you can select a developer preview version from the drop-down list. Development stores that use a developer preview can't be transferred to a merchant.

6. Under Data and configurations, choose whether to start with an empty store, or with a store that's populated with test data generated by Shopify. Stores that start with generated test data can't be transferred to a merchant.

7. Click Create development store.

When you're done working on a development store, you can archive it.

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 user'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's released to users.

To learn more about the API release schedule, refer to 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 app extension to build apps that enable users to track and send buyer behavioral data to a third-party service.

• Order status page extensions: Order status page extensions enable you to add new UI and functionality to the order status page.

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

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.

For our Shopify Unite 2019 annual developer conference, we released a special edition of developer preview, which included the following features:

• New online store design experience

• Order editing

• Support for 3D and video media for products

• Selling in multiple languages

• Tax exemptions

Going forward, all developer previews will be published as needed. You can learn about the features in each developer preview in the API version release notes.

The Online Store color scheme developer preview gives you access to the following new input setting types for Online Store themes:

• color_scheme
• color_scheme_group

Use color_scheme_group to define the structure of a color scheme in settings_schema.json, and then set values for the color scheme in settings_data.json. You can allow app users to apply these color schemes at the theme, section, or block level using the color_scheme setting, which outputs a color scheme picker.

You can also use the Liquid color_scheme_group object to define new color schemes, so that app users no longer need to edit their CSS or Liquid files to add or remove color schemes.

Learn more about color_scheme and color_scheme_group settings.
