Shopify Release Notes

As of version 2026-07 of the GraphQL Storefront API, the Cart object issues a warning when a buyer's selected delivery option becomes unavailable.

Previously, if a buyer's chosen delivery option was no longer available (for example, after changes to the cart's address or contents) the system would automatically switch to a different option without notifying the buyer. This lack of notification made it challenging for developers to inform buyers of the change.

Now, with the introduction of the DELIVERY_SELECTED_OPTION_NOT_AVAILABLE value in the Cart Warning, developers can programmatically detect when a selected delivery option is unavailable. This allows you to prompt buyers to confirm or choose a new delivery option, ensuring they are aware of any changes.

As of API version 2026-04, the new Checkout And Accounts Configuration API is now available to unlock consistent branding customizations across checkout, customer accounts, and sign-in surfaces. This API is exclusively available to Shopify Plus merchants.

This new API replaces the Checkout Profile API and Checkout Branding API (both are now deprecated). All capabilities to customize settings and branding for checkout, and customer accounts, and sign-in are now consolidated into one single API.

What you can do:

• Shared branding settings: Use shared designTokens and components to set branding once and apply consistently across checkout, customer accounts, and sign-in pages. Section styles (padding, shadows, colors, borders, and border radius) previously available for checkout only can now be applied to customer account pages.

• Surface-specific overrides: Apply targeted overrides under surfaces.checkout, surfaces.customerAccounts, and surfaces.signIn for logos, colors, and section styles.

• Direct color settings: Set color using HEX values or palette colors directly on sections like main, header, and orderSummary — no more mapping through a limited number of color schemes. Save your brand colors to an editable color palette of up to 20 colors and reference anywhere you make a color selection. Update a palette color, and it changes everywhere it is referenced.

• Customize branding per market: Customize your pages for each market with unique branding settings.

We’ve published new migration guides to help you upgrade Checkout and Customer Account UI extensions to the latest API version and Polaris web components.

The new guides include:

• Guidance for moving from React or JavaScript extension APIs to Preact, Polaris web components, and the global shopify object.
• More than 60 component-specific migration pages, covering components such as Button, Checkbox, Text Field, Banner and View for Checkout and Customer Account UI extensions.
• Instructions for migrating checkout metafields to cart metafields

If your extension uses an API version earlier than 2025-10, use these guides to adopt Polaris web components, which are the default in API version 2025-10 and later.

The App Events API lets you send any event from your app to Shopify. App event data appears in your Dev Dashboard Logs alongside webhooks, Function executions, and API calls.

How it works:

1. Send app events to a single API endpoint: Define the event_handle and attributes you want to track and send them to the App Events API, including:

   • Feature usage: bulk_edit_completed, report_generated, automation_created
   • Workflows: onboarding_completed, campaign_sent, export_finished
   • Performance: sync_failed, api_timeout, rate_limit_hit
   • Conversion signals: limit_hit, premium_viewed, milestone_achieved
   • Billable activities: order_processed, email_sent, label_printed

2. View events in Dev Dashboard: All app events flow into Dev Dashboard Logs automatically for monitoring, alongside data Shopify provides about your app, i.e: Webhooks, Functions executions, and API calls.

3. Optional: Turn app events into billing: On Shopify App Pricing, any app event can become a usage-based charge. Define a meter in the Partner Dashboard, match it to an event_handle, and Shopify handles metering and invoicing. No additional code required.

App Events is available now for all apps, regardless of billing method.

What's new:

Managed Pricing is now Shopify App Pricing

Shopify App Pricing replaces Managed Pricing as Shopify’s default billing solution that gets configured during app submission in the Partner Dashboard. Apps previously on Managed Pricing will now see “Shopify App Pricing” as their selected billing solution.

Usage-based billing now possible with App Events API

Charge based on merchant usage using the App Events API. Send events from your app, define meters in the Partner Dashboard, and Shopify handles aggregation, calculation, and invoicing. Three pricing structures supported: fixed, graduated, and volume. Supports negative reporting for automatic charge corrections.

New APIs make billing data more accurate

Active Subscription API: Real-time subscription status (active, pending, cancelled, frozen) that persists beyond uninstall
Historical API: Full event log of installs, uninstalls, subscription changes, charges, credits, and usage

Transparent billing in the admin

Merchants see a billing card on the app settings page in the Shopify admin that displays their current plan, subscription status, usage charges, and upcoming pricing changes — including downgrades. This is the same information surfaced through the Active Subscription API.

Billing API marked as legacy

The Billing API continues to function but is now legacy. All apps should use Shopify App Pricing going forward.

What this means for your billing:

• Apps with no active charges: Shopify App Pricing is the default. Configure pricing during app submission. [Learn more]
• Existing apps with active charges on Managed Pricing or Billing API: Your current billing continues without changes. Migration tooling will be available soon to support the transition to Shopify App Pricing. Learn more.
