Ecommerce checkout orchestration retrieves the cart, validates payment methods, applies shipping, calculates totals, and creates orders with line items. This enforces a consistent flow through validation and atomic transactions to ensure order integrity.

Validating payment and shipping during order creation requires a unified checkout flow that ties cart retrieval, payment validation, and shipping application into a single transaction. This ensures order integrity by checking stock and calculating totals atomically.

Checkout endpoints handle cart cleanup by clearing the cart immediately after order creation and payment recording. This ensures atomic transactions by tying cart, shipping, payment, and stock checks into a single end-to-end flow.

This checkout flow applies to online stores from cart to order across shipping, taxes, and payments scenarios. It calculates totals while applying shipping, ensuring end-to-end coherence for ecommerce checkout processes.

Ecommerce checkout fails when cart validation and payment processing are not tied into a single atomic transaction. A consistent flow enforcing CheckoutDto validation, totals calculation, and order creation prevents cart abandonment and checkout friction.
