Client systems use this endpoint to submit new order instructions to buy or sell crypto on behalf of an investor.
The order processes asynchronously. The system allows duplicate submissions; however, order details must NOT change in subsequent requests. Orders are uniquely tracked for idempotency by the submitting system providing the clientOrderId field.
Clients can provide the amounts to purchase or sell crypto in two different ways:
Notional - Using the notional field, an investor may place an order for crypto given a USD amount to purchase. For example, an investor can buy $100 of BTCUSD at market price by entering 100 in the notional field. Absolute - Using the quantity field, an investor may place an order for an exact amount of crypto. For example, an investor can sell 0.05 BTC for USD by entering 0.05 in the quantity field.
