What happened
Google updated its Universal Commerce Protocol (UCP), adding new capabilities for AI shopping agents. UCP now supports multi-item cart functionality, real-time product details like pricing and inventory from retailer catalogues, and Identity Linking for loyalty benefits on integrated platforms. Google also simplified UCP onboarding in Merchant Center. Partners including Commerce Inc, Salesforce, and Stripe will implement UCP, extending agentic shopping experiences across Google's AI Mode in Search and the Gemini app.
Why it matters
Retailers gain streamlined integration for AI-powered shopping experiences, reducing friction for customers and enabling loyalty program recognition across platforms. UCP's enhanced agent capabilities offer platform engineers and e-commerce founders improved conversion funnels and customer retention, particularly as Google integrates these features into AI Mode in Search and the Gemini app. This follows Google's initial launch of UCP-powered checkout in AI Mode earlier this year, which enabled direct purchases from retailers like Etsy and Wayfair.
