Orders

Create order

Creates a new order for crypto/fiat conversion using a previously created quote.

Flow:

First, call POST /ramp/quote to get pricing and create a quote.
Then, call this endpoint with the quoteId to execute the order.

The order inherits the blockchain, direction (onramp/offramp), and amounts from the quote. Quotes expire after 2 minutes, so create the order promptly after getting the quote.

Wallet resolution: provide either publicKey or cryptoWalletId (or both). When cryptoWalletId is provided (typical for embedded wallets), publicKey, blockchain, direction, and amount fields are optional — they are derived from the quote and wallet record.

For onramps, the bank account must belong to your organization or a child organization.
