# Place an order

`POST /orders`

Places a new order for an instrument. After the request is accepted, the order is processed asynchronously — use the returned `id` to poll for status or subscribe to order webhook events.

See the Orders guide ([TOL](https://docs.upvest.co/products/tol/guides/orders) / [BYOL](https://docs.upvest.co/products/byol/guides/orders) / [Omnibus](https://docs.upvest.co/products/omnibus/guides/orders)) for order lifecycle details.
