commercetools has launched the Commerce Integration Layer, a centralized integration platform designed to eliminate redundant middleware development across commerce implementations (commercetools Blog). The Layer provides five core capabilities: an Experience API built on GraphQL, a command-line interface for developers, a Merchant Center admin UI, Platform Insights for observability, and managed hosting. It is included at no extra cost with commercetools Sphere (commercetools Blog).
Integration has historically been one of the most time-consuming parts of commerce implementations, frequently cited as a major reason projects take months to complete (commercetools Blog). The Layer addresses this by allowing teams to model integrations once and deploy them across all customer-facing surfaces—storefronts, mobile apps, and AI agents—without rebuilding the same backend-for-frontend services. For commerce practitioners, this reduces launch delays, lowers maintenance costs, and frees engineering capacity to focus on competitive differentiation rather than undifferentiated glue code.
Early partners including IONA and Zaelab have begun building projects on the Layer, with IONA reporting that refactoring an existing backend-for-frontend took only weeks, allowing future projects to skip foundational infrastructure work entirely (commercetools Blog). The Layer also prepares partners for agentic commerce by sharing the same API contracts between shopping agents and storefronts.
