Medusa cart and checkout orchestration uses flow wrappers instead of direct SDK calls to manage state transitions across client and server boundaries, ensuring consistent cart lifecycle and predictable checkout sequences for adding to cart, shipping, and payment.

Flow wrappers replace direct Medusa SDK calls to reduce boilerplate and enforce canonical checkout lifecycles. This provides shared cache synchronization and error handling, preventing ad-hoc state transitions during cart updates, shipping, and payment finalization.

Manage the Medusa cart lifecycle and region handling by utilizing storefront cart flows. These wrappers coordinate creation, updates, and region transitions consistently, avoiding ad-hoc state changes and maintaining synchronized cache across boundaries.

Yes, this flow wrapper approach supports cart and checkout across client and server boundaries. It leverages storefront-data integration to provide shared cache synchronization and predictable behavior for shipping, payment, and checkout finalization.

The best way to drive shipping and payment sequences is using checkout flow wrappers. They enforce a canonical sequence for finalizing checkout, handling state transitions and cache synchronization predictably rather than relying on direct, ad-hoc SDK interactions.
