You can consolidate commerce microservices by implementing an API gateway using GraphQL Federation with Apollo Router or a REST BFF pattern with Fastify. This aggregates catalog, inventory, cart, and CMS services into a single endpoint.

To reduce high API call volume in a headless storefront, use an API gateway for API orchestration. It consolidates dozens of backend microservice requests into a few efficient gateway calls, improving frontend performance.

GraphQL Federation works with composable commerce by using Apollo Router to aggregate disparate microservices into a unified schema. It enforces cross-cutting concerns like authentication, rate limiting, caching, and distributed tracing.

Yes, you can enforce unified authentication and rate limiting across backend services by applying them at the API gateway layer. This ensures consistent policy enforcement across all commerce microservices.

Yes, the API gateway supports both patterns, allowing you to configure Apollo Router for GraphQL Federation or implement a REST BFF pattern using Fastify to aggregate your commerce microservices.

You should use an API gateway for headless commerce when your storefront makes high volumes of API calls per page. It simplifies client interactions and handles cross-cutting concerns like caching and distributed tracing.
