Catalog Service and Product Recommendations Improvements

January 2024 brought significant enhancements to Adobe Commerce's Catalog Service API, with the addition of related products data and substantial performance improvements for product detail page (PDP) load times. These updates strengthen the platform's headless commerce capabilities and provide merchants with faster, more flexible ways to access product information.

Related Products in Catalog Service API

Previously, merchants using Catalog Service for headless storefronts had limited access to related product recommendations. The January update exposes related, up-sell, and cross-sell product data directly through the Catalog Service GraphQL API, eliminating the need to make additional API calls to fetch related products separately. This reduces API latency and simplifies integration logic for headless applications.

For composable storefronts, this means smoother product discovery flows and improved customer experience without architectural complexity. Product detail pages now load faster with all necessary relationship data available in a single request.

Faster PDP Load Times

Adobe optimised the Catalog Service backend to reduce response times for product queries. Merchants building headless applications report 20-30% faster PDP load times, a meaningful improvement for conversion-focused businesses where every millisecond counts. These performance gains translate directly to better Core Web Vitals scores and improved search engine rankings.

What This Means for Merchants

Headless commerce merchants benefit from simplified integrations, faster customer experiences, and reduced API usage costs. The addition of related product data within a single API response streamlines development workflows and enables faster time-to-market for new storefront features. For merchants committed to composable architectures, these improvements reinforce Catalog Service as the optimal choice for product data access.
