# 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`](https://developer.salesforce.com/docs/atlas.en-us.chatterapi.meta/chatterapi/connect_resources_commerce_webstore_checkouts_place_order.htm)

**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.
