Get one order

GET/orders/{orderId}

The single-Order detail read: the same snake_case order body as the webhook `data` and the poll items, through the one shared serializer. Once the Order has transitioned it carries the additive `status` / `fulfillment` fields; both are absent while the Order is still `created`.

When to use

Use this operation to get one order.

Errors

Status	Code	Meaning	Do this
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.
