Google Introduces Universal Cart in the U.S.
Google has officially unveiled its Universal Cart in the United States, now accessible through both Google Search and the Gemini app.
This innovative feature empowers customers to compile items from a variety of retailers into a single cart.
Furthermore, it offers valuable notifications about price reductions and stock availability, enabling users to finalize their purchases either through Google Pay or by navigating directly to the retailer’s website at participating stores.
In a recently released blog post, Suresh Ganapathy, Senior Director of Product Management for Consumer Shopping, highlighted the significance of this launch. The concept of the Universal Cart was first introduced by Google during the I/O event in May.
Functionality of Universal Cart
The Universal Cart allows users to seamlessly incorporate products from various retailers while shopping via Search, including AI Mode, and within the Gemini app.
Users can consolidate all their selected items into one comprehensive cart. Additionally, alerts are dispatched when a previously saved item experiences a price drop or becomes available again.
This feature is integrated with Google Wallet, which suggests optimal payment cards based on available perks and displays applicable promotional codes directly within the cart.
Notable merchants collaborating with Google for in-cart checkout include Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair, and a multitude of Shopify merchants. Importantly, the merchant remains the official seller of record throughout the transaction.
Updates Since the May Announcement
In its earlier I/O announcement, Google anticipated that users in the United States would gain access to the Universal Cart by the close of summer.
It was also indicated that YouTube and Gmail would eventually accommodate this feature. However, the latest announcement omits any reference to the timeline for YouTube and Gmail.
The original May communication described additional features including historical pricing information, interoperability warnings related to shopping cart products, and details about loyalty programs connected to Google Wallet.
These enhancements were conspicuously absent from the recent update, suggesting a possible alteration in scope.
The launch communication distinguishes between agentic features acting on behalf of shoppers and those that “instill confidence and control” in the shopping experience, categorizing the cart firmly within the latter.
Merchant Integration and Cart Functionality
Google’s developer documentation connects the cart transfer functionality to the Cart API under the Universal Commerce Protocol (UCP).
According to the Cart API guide, the API enhances Universal Cart capabilities by generating a cart within the merchant’s framework via a CreateCart command upon item transfer by the shopper.
This inaugural version permits only unidirectional cart creation and transfer. Notably, updating or synchronizing cart contents between Google and the merchant’s systems is not currently supported. The native checkout mechanism on Google utilizes a separate API and is not a prerequisite for cart transfers.
Participating merchants meeting Google’s onboarding criteria can opt for either integration method via the UCP hub in the Merchant Center
. Google’s help page notes that this hub will gradually be made available in the U.S., with Australia and Canada set to follow next year.
Merchant Insights and Analytics
The UCP Analytics Reporting dashboard within Merchant Center meticulously tracks the checkout journey, from clicks on the purchase button to the point of sale and any cancellations.
The Merchant API reference similarly enumerates cart transfer metrics, including the quantity of cart transfers completed and the average cart value at transfer, with both types of metrics being equivalent in the Merchant Center dashboard.
It is important to note that the API reporting is currently in alpha testing phase, and no metrics are available for products saved in carts.
According to Shopify’s support documentation, Direct Checkout is automatically activated for eligible U.S. Shopify Stores through the Google AI Mode & Gemini Channel.
However, it is noted that Google Analytics and Custom Pixels will not be activated when purchases are completed via the Direct Checkout channel.
Unfortunately, there remains a dearth of information regarding the management of in-cart purchases from Shopify merchants using the Universal Cart feature.
Significance of Universal Cart
The introduction of Universal Cart positions a buyer’s shopping list centrally within their Google account, allowing for convenient checkout directly through this interface.
Google delineates two distinct methods for completing transactions from Universal Cart: “Native checkout,” where the sale is completed via Google, and “Cart Transfer,” which facilitates the creation of a pre-filled shopping cart upon accessing the merchant’s website.
The UCP sales tracking framework monitors both cart transfers and purchases separately. Importantly, purchases recorded by the tracking system for Universal Cart encompass all completed transactions originating directly from the shopper’s Universal Cart shopping list.
Any purchases made after transferring items to a merchant’s website will be executed at that merchant’s location.
Shopify stores can verify whether direct checkout is enabled via the Sales channels > Agentic section in the Shopify Admin.

Future Prospects
The rollout of Universal Cart is currently underway across the United States, strategically timed before the onset of the holiday shopping season.
The announcement today does not present any timelines regarding the integration of YouTube or Gmail, both of which Google had indicated would be supported at a later date.
Provided that merchants have been granted access to the UCP integration hub, they should continue to track buy click activities, purchase conversions, and cart transfers through the analytics tab.
