Create a sell order (USDT in, KES out)

Consumes a sell quote and returns your deposit address. Payout is asynchronous: nothing is paid out until you attach the transaction hash of your USDT send with PATCH /v1/orders/{id} and the order reaches a terminal state. A signed webhook tells you when it settles; polling is the fallback. Retry-safe: creating twice with the same partnerReference returns the original order rather than a second one. Your deposit address is the same for every order, so we cannot tell your orders apart by it — the transaction hash is what attributes a deposit.

curl -X POST "https://example.com/v1/orders/sell" \  -H "Content-Type: application/json" \  -d '{    "quoteId": "string",    "partnerReference": "string",    "payoutAccountId": "string"  }'
