Shopify News September 2026: The Most Important Updates

Shopify made several changes to its platform again in September 2026. In addition to a new look for the Shopify Admin, there were updates to Analytics, Payments, and WhatsApp marketing. At the same time, Shopify is increasingly focusing on AI, agentic commerce, and the question of how products and stores will be accessible via AI agents in the future.

There were also some changes for developers that may be relevant to existing apps and Shopify Plus projects. We’ve summarized the most important Shopify news from September.

Shopify Admin Gets a New Design

Since September 15, Shopify has been gradually rolling out a new design for the Shopify Admin. Changes include colors, typography, spacing, and icons. The navigation also looks different: Search, notifications, and the store switcher are now located in the sidebar. This sidebar can be collapsed to free up more space for your actual work.

Shopify Sidekick has also been given a new home. The AI assistant is no longer located in a side panel but appears as a floating chat at the bottom of the Admin. This allows Sidekick to be opened regardless of which Admin page is currently open.

No adjustments are necessary for merchants. The new design is being rolled out gradually. For developers, the change is somewhat more significant: Admin UI Extensions and App Home UI Extensions automatically adopt the new styles. Custom app interfaces, on the other hand, can remain in the previous design until the switch to Polaris 2.0 is complete.

In line with this, Shopify also advanced the development of Polaris in September. The new semantic versioning approach for the Polaris CDN ensures that major version jumps must be explicitly adopted.

Shopify Analytics Introduces New Session Tracking

Since September 21, Shopify has been measuring sessions differently in Analytics. Bot and system traffic are now more accurately distinguished from human visitors. At the same time, valid visits can be recorded as sessions even if no traditional pageview occurs.

This can have a significant impact on existing reports. Among other things, the values for sessions, conversion rate, add-to-cart rate, checkout conversion, bounce rate, pageviews per session, and online store visitors may change.

It’s important to note that this does not automatically mean that actual traffic or purchasing behavior has changed. Orders, revenue, and customer numbers are not affected by this change.

For analysis purposes, September 21 should therefore be considered the new baseline. Anyone comparing September’s performance to previous months should keep the changed measurement method in mind.

Product variants can now manage up to 20 barcodes

Multiple barcodes per product variant are now possible. Up to 20 barcodes can be assigned to a single variant. In addition, a type can be specified for each barcode, such as GTIN, UPC, EAN, ISBN, or ASIN.

This is particularly useful for stores that track products using different identifiers. One example is the book trade: A book is typically identified by its ISBN, while other products in the same product line may have a GTIN.

This exact scenario applies to our client, DK-Verlag. The company primarily sells books, but it also carries other products with different product identifiers. With the previous single barcode field, it was not possible to immediately distinguish whether a value was an ISBN or a GTIN. Thanks to the new barcode type, this information is now stored directly in the barcode.

The functionality has also been expanded for Shopify POS. Variants can be searched for or scanned using any of the stored barcodes.

Technically, the barcodes can be read via the new barcodes structure and written using methods such as productSet, productVariantsBulkCreate, and productVariantsBulkUpdate, among others.

WhatsApp Marketing: Opt-in Now Directly at Checkout

The WhatsApp channel continues to expand. Since September 10, merchants have been able to collect consent for WhatsApp marketing directly during checkout.

Customers can give their consent during the purchase and will then be contacted for WhatsApp marketing. Consent is managed in Shopify and can be used for relevant marketing activities.

This adds another touchpoint for building a WhatsApp subscriber list directly within the purchase process. Previously, merchants could collect consent through Shopify Forms, among other methods.

As with other marketing channels, consent must be obtained and processed in accordance with applicable legal requirements.

Meta Becomes an AI Channel in Shopify

The Agentic Commerce initiative continues to expand. As of September 8, Meta appears as a separate AI channel in the Shopify Admin. By default, products are shared with Meta via the Shopify Catalog.

Merchants can configure how the Catalog and Direct Checkout are used in the settings. The channel’s performance can also be viewed within the corresponding Agentic Storefront settings.

This means Shopify products can no longer be displayed solely through the traditional online store or established sales channels. New AI-based shopping experiences are also becoming part of the commerce infrastructure.

Please notice: This selling channel is not available for every merchant at the moment. One requirement is that you sell to customers in the US, Mexico or Canada.

For merchants, this places even greater emphasis on the quality of product data. Product names, variants, prices, availability, and other catalog information must be structured in such a way that they can be processed effectively even outside the merchant’s own store.

Especially with regard to AI Search and Agentic Commerce, the question of whether a product is not only discoverable but can also be clearly understood and used by other systems is becoming increasingly important.

Category meta fields and meta objects can be used in Shopify Analytics

There are also new possibilities in Analytics. Category meta fields such as color, material, fit, or size can now be used directly in reports as dimensions and filters.

This allows you, for example, to analyze sales by color or material. If products already have the corresponding category meta fields, merchants don’t need to set up anything additional.

Metaobject fields were also added at the end of September. This allows custom structured information from metaobjects to be used in Analytics, such as designer, country of origin, warranty information, or loyalty tiers.

This is particularly useful for stores with extensive product data. The structured information already available in the store can thus be more closely linked to sales and performance data.

WebMCP Brings AI Agents All the Way to Checkout

The capabilities of AI agents are being expanded at checkout. With WebMCP support, browser agents can interact with Shopify Checkout.

Among other things, agents can read the checkout status, update supported checkout data, and complete the purchase after the customer confirms.

This builds on the WebMCP features already introduced for storefronts and the shopping cart. The agent can thus handle a larger portion of the purchase process, rather than just assisting with product search or shopping cart setup.

For merchants, this is primarily a development to watch for now. For developers, it’s more concrete, as new APIs are being created for agent-based interactions with the storefront and checkout.

Other Important Changes for Shopify Developers

In addition to the major features, there were several changes in September that are particularly relevant for app developers.

Events: Query Limit Reduced from 250 to 100 Points

The maximum query complexity for Events Subscriptions is being reduced from 250 to 100 points. Classic webhooks are not affected by this change.

Developers should therefore review existing subscription queries. Shopify recommends retrieving only the data that is actually needed for the specific event. For example, if only the price of a modified variant is needed, there’s no need to load the entire product—including all variants—every time.

This may require adjustments to existing apps and is therefore one of the developer changes that should not be overlooked.

You can now create an unlimited number of private plans

There’s also more flexibility with Shopify App Pricing. Since September 21, developers have been able to create an unlimited number of private plans per app and assign an unlimited number of target stores to a plan.

The previous limits were 15 Private Plans and 20 stores per plan. This makes management significantly more flexible for apps with custom pricing or special terms for individual B2B or Enterprise customers.

Metafields Now Have a “translatable” Field

With API version 2026-10, the GraphQL Admin API introduces a new boolean field, “translatable,” directly on the Metafield object.

Apps can now immediately determine whether a Metafield value is translatable. Previously, the separate TranslatableResourceType.METAFIELD mechanism had to be used for this purpose.

For apps that work with translatable metafields, migration to the new API version should be reviewed accordingly.

UI Extensions: Exceptions Possible for Oversized Bundles

There is also a change regarding UI extensions. Extensions with API version 2025-10 or higher are generally limited to 64 KB of compressed JavaScript per extension. Full-page customer account extensions may be up to 128 KB in size.

If an existing extension cannot be brought below the limit despite optimization, an exception can be requested from Shopify. Among other things, Shopify will review whether the additional bundle size is actually necessary. Large libraries, duplicate dependencies, or embedded translations, for example, are not considered sufficient justification.

Our Tech Lead and developer Gianluigi Zarrelli considers this point particularly important. For Latori, this is especially significant when a UI extension in a project reaches the bundle limit.

Polaris CDN 1.1 is stable

Polaris is also relevant for developers working on Shopify apps. Polaris CDN 1.1 has been stable since September 22. Shopify continues to use the new semantic versioning model: Minor releases can automatically roll out compatible changes, while a major release must be manually adopted.

This gives developers more control over when major changes are implemented in an app. Developers who hard-code the CDN version can also choose to stay on a specific Polaris version.

Hydrogen Gets New Features

There were also several changes to Hydrogen in September. The Developer Preview included, among other things, variant links, improvements to cart refreshing, and a simplified setup process for local HTTPS certificates.

Variant links can point directly to a specific product variant. This can be useful, for example, for links from product feeds. In addition, the cart can be refreshed more precisely after changes using custom code.

For headless projects using Hydrogen, such changes are less visible than new store features, but they can significantly impact day-to-day development work.

Conclusion: Shopify Continues to Evolve Toward AI and More Complex Commerce Setups

In September, Shopify wasn’t just about individual new features. Several updates show that the platform is continuing to evolve in various areas.

For merchants, the focus is on analytics, WhatsApp, payments, and structured product data, among other things. At the same time, the technical foundations for AI- and agent-based shopping experiences are being further expanded. Meta as an AI channel and WebMCP for checkout are two good examples of this.

For developers, new requirements are emerging in parallel—such as those related to events, subscriptions, UI extensions, and API versions. Especially for existing Shopify Plus projects, it’s therefore worth regularly reviewing the changes in the changelog.

That’s because not every update affects the store immediately. Some changes only become significant when an existing app, integration, or custom solution is impacted.
