Cancel an order

POST/orders/{orderId}/cancel

The pre-ship termination command: legal from `created` or `accepted` only. `lines` is the optional subset to cancel (each sku at most once); omitted cancels the whole Order. A Cancellation always restocks on the Snapcaster side and emits an `order.cancelled` webhook (or the compensating positive `inventory.adjusted`, per the Platform’s Subscription), including back to the caller. Returns the post-cancel Order.

When to use

Use this operation to cancel an order.

Errors

Status	Code	Meaning	Do this
400	INVALID_REQUEST	The request failed validation (`INVALID_REQUEST`).	Correct the fields named in the error details, then retry the request.
401	UNAUTHORIZED	Missing or invalid Marketplace API key (`UNAUTHORIZED`).	Send the Marketplace API key for this Seller as a Bearer token, then retry.
404	ORDER_NOT_FOUND	No such Order for this Seller (`ORDER_NOT_FOUND`). A Seller-scoped miss (including another Seller’s order id) is always a 404, never a 403, so order ids don’t leak existence.	Check the order_id against GET /orders for the authenticated Seller, then retry with that id.
422	INVALID_TRANSITION	The move violates the Lifecycle transition graph (`INVALID_TRANSITION`). For example, a backwards move, a pre-ship Refund, or a post-ship Cancellation.	Read the Order again and submit only a legal next transition, using the dedicated cancellation or refund operation when applicable.
