Commerce Webstore Checkout Orders API

Use for simple, synchronous checkout scenarios with minimal customization. The Commerce Webstore Checkout Orders API is also referred to as Place Order V1.

Endpoint: POST /commerce/webstores/{webstoreId}/checkouts/{activeOrCheckoutId}/orders

How it works:

• Invoke single-step Place Order API (no request body required).
• The API performs all validations and places the order in a single call.
• On success, returns 201 Created with Order Reference Number (ORN).
• On failure, returns 422 Unprocessable Entity.

Call after:

• Payment APIs have completed.

Supported cart states:

• Checkout
• PendingClosed (returns existing ORN)

Execution flow:

• Validations, inventory, coupon processing, and order placement execute in a single call.
• Cart-to-order processing runs asynchronously after API call.
