What is the Universal Commerce Protocol (UCP)?

UCP is the standard that lets AI shopping agents read Shopify catalogues and build carts. Since the Summer 2026 Edition it is enabled by default on every Shopify store – products are discoverable to agents without sellers building a custom connection. In practice that means the question is no longer whether your store becomes agent-ready, but whether your product data is good enough to win inside agent answers.

Do I have to set anything up for agentic storefronts?

Shopify handles the basic connection: eligible products auto-syndicate to AI surfaces such as ChatGPT, Microsoft Copilot, Google AI Mode and Gemini. Your work is in the data – complete attributes, clear product copy, correct availability and competitive terms decide whether an agent recommends your product or your competitor's.

What happened to Shopify Scripts?

Shopify Scripts was fully retired on June 30, 2026. Discount, shipping and payment logic that hadn't been migrated to Shopify Functions stopped working on July 1. If any affected logic hasn't been moved yet, treat it as a production incident – Functions is the only supported path for these customisations.

Is native A/B testing available on all plans?

With the Summer Edition, Shopify introduced native A/B testing for themes and checkout configurations, making third-party tools unnecessary for many standard test cases. Checkout-level customisations and components remain partly reserved for Plus, though – check the current plan details in your admin to see what's included in yours.

What does Sidekick actually deliver day to day?

Two things are practical: theme changes via natural language (phrases like “make this button round” change the right setting directly) and executable tasks such as creating discount codes or tagging products on command. Sidekick Skills additionally let teams save and share proven prompts. It remains an assistant – reviewing its output stays part of the job.

Shopify in 2026: The Updates That Matter From Both Editions

Shopify Editions 2026 at a glance: Universal Commerce Protocol, agentic storefronts, Sidekick, native A/B testing and the Scripts shutdown – what sellers should know and do now.

Shopify ships its news in two big packages a year – and both 2026 Editions, with 150+ updates each, shared one thread: AI moving from feature to infrastructure. The Winter Edition (“Renaissance”) made the admin conversational; the Summer Edition (“Everywhere”, presented June 17) switches commerce on inside AI assistants – by default, for every store. Here is the selection of updates that actually matter for sellers, with context on what to do. As of July 2026.

Key takeaways

The Universal Commerce Protocol (UCP) is active on every store since the Summer Edition – AI agents can read catalogues and build carts.
Eligible products auto-syndicate to ChatGPT, Microsoft Copilot, Google AI Mode, Gemini and the Shop app.
Sidekick now changes theme settings via natural language, builds Flows and executes simple admin tasks directly.
Native A/B testing for themes and checkout configurations replaces external testing tools for standard cases.
Shopify Scripts has been shut down since June 30, 2026 – unmigrated discount and shipping logic no longer runs.

Winter Edition: the admin becomes conversational

The “Renaissance” edition at the start of the year was about operation. Sidekick has understood natural language as a control layer since then: theme changes (“make this button round”) land directly in the right settings, and Flow automations can be described instead of assembled – “auto-tag customers who order above 200 euros” becomes a finished, visualised workflow. Sidekick Skills let you save proven prompts and share them across the team.

On top came tangible catalogue improvements: products with up to 2,048 variants, selectively hiding products from search and collections while keeping them reachable via direct URL, and a much stronger Bulk Operations API (all admin mutations, files up to 100 MB, five parallel operations) – relevant for anyone moving large catalogues or migrations.

Summer Edition: commerce everywhere – including chatbots

The “Everywhere” edition is the strategically bigger one. Its core: the Universal Commerce Protocol, active by default on every Shopify store, allowing AI agents to read catalogues and build carts. On top, Shopify auto-syndicates eligible products to ChatGPT, Microsoft Copilot, Google AI Mode, Gemini and the Shop app – a customer can discover and buy a product without ever seeing your website. We covered what that means strategically in agent-ready commerce; how stores become visible in AI answers is the subject of LLM optimisation.

Three more updates have direct everyday value: native A/B testing for themes and checkout configurations (no third-party tool needed for standard tests), Checkout Components generally available on Plus, and Campaign Autopilot – a campaign agent that takes a budget and guardrails, plans ad strategy across Meta, the Shop app and email, submits it for approval and keeps adjusting. Shopify Magic also got noticeably better: product copy now follows your existing texts and brand tone instead of generic patterns.

The deadline that already passed: the Scripts shutdown

Since June 30, 2026, Shopify Scripts is fully retired – discount, shipping and payment logic that wasn’t migrated to Shopify Functions simply stopped running on July 1. If you see unexplained checkout behaviour, check here first. The migration is no longer a project – it’s incident response.

From practice: Editions announcements are marketing – the substance sits in the changelogs and plan details. Before any switch, check which function is actually included in your plan; checkout features in particular have traditionally been Plus-heavy.

What to do now

Scripts check: Any old Script logic still assumed to run? Since July that’s a production bug – migrate to Functions immediately.
Make product data agent-ready: Complete attributes, precise copy, clean availability – UCP turns them into your shop window for AI agents.
Review A/B testing natively: Hold existing test tools against the new built-in – often a subscription can go.
Pilot Sidekick with the team: Hand it two or three recurring admin tasks via language and share them as Skills – the time saving is real, the review stays mandatory.
Test Campaign Autopilot with guardrails: Small budget, clear limits, results held against your own performance numbers.

Bottom line

2026 is the year Shopify turned agentic commerce from vision into default: UCP and auto-syndication put every store inside the AI assistants – the quality of your product data decides what arrives there. Native A/B testing and an action-capable Sidekick make the day-to-day concretely easier on top. The next sensible step: schedule the Scripts check and the product-data audit from the list above this week.
