As digital commerce evolves at a fast pace, traditional monolithic commerce platforms have created some architectural issues, especially in scenarios where businesses need to engage customers across all channels, deliver features quickly, and continuously scale up. Modern, tightly coupled, on-premise commerce architectures were hard to extend, integrate and modernise as businesses increasingly embraced a mobile-first experience, cloud-native platforms and distributed digital ecosystems. This paper proposes an application programming interface (API) based architecture model of enterprise commerce that is optimised for delivering composable digital ecosystems with decoupled storefronts, service-oriented integration layers and scalable backend orchestration patterns. The proposed architecture highlights a headless commerce approach that decodes the delivery of customer experience from the transactional commerce services, allowing organisations to grow their frontend channels and backend business functions separately. The framework highlights API-first design principles, modular service integration, reusable orchestration layers, and cloud-native deployment strategies, contributing to enhanced architectural flexibility and sustainability. In the context of large-scale commerce modernisation projects across areas of distributed systems integration, high-volume transaction environments and multi-channel customer engagement, enterprise implementation patterns are explored. Data from a synthesised literature indicates that composable architectures offer gains in deployment frequency of 4-10 times over monolithic baselines, and mean time to recovery (MTTR) of around 75% and lead time for change of around 85% reduction. Moreover, in the context of omnichannel retail, the integration of the channels is proven to bring about 40–60% enhancements in customer satisfaction. The results show that composable commerce architectures serve as the backbone for digital transformation in enterprises, enhancing agility, speeding up the innovation process, and enabling the flexibility of customer interaction trends
