When set to `true`, the order can only decrease or close an existing position — the order never increases the position or opens a new one. **Behavior:** * If the order amount exceeds the current position size, the system automatically reduces the order to match * The API returns error code `116` if no open position exists or the order direction matches the position direction * Pending reduce-only orders are auto-canceled with status `AUTO_CANCELED_REDUCE_ONLY` when the associated position closes **Supported on 6 collateral order creation endpoints:** The `reduceOnly` field also appears in the response of [query active orders](/api-reference/spot-trading/query-unexecuted-orders), [query executed orders](/api-reference/spot-trading/query-executed-orders), and [query conditional orders](/api-reference/collateral-trading/query-unexecuted-conditional-orders). **WebSocket channels:** The `reduce_only` field is added to the [Orders Pending](/websocket/account-streams/orders-pending) and [Orders Executed](/websocket/account-streams/orders-executed) channels — both in query responses and real-time update events. ## Previous Changes ## Mining Pool API **Comprehensive mining pool management endpoints** Introduced a complete Mining Pool API with 10 endpoints for managing mining operations, including account monitoring, payout configuration, worker management, and watcher link generation. **Public endpoints:** * Pool statistics and connection information **Mining account management:** * Reward history with pagination * Account-level hashrate monitoring with configurable intervals (5m, 1h, 24h) * Fee and stratum connection details **Payout configuration:** * Get and set payout destination (main balance or external BTC address) * Support for all standard Bitcoin address formats **Worker monitoring:** * List online workers with pagination * Individual worker hashrate history **Watcher links:** * Create read-only access links with granular permissions (dashboard, rewards, workers) * Configurable expiration periods (1h, 24h, 7d, always) * List active watcher links All authenticated endpoints require the MINING\_POOL feature to be enabled on the API key. ## Mining Account Management **Create and list mining accounts** Added endpoints to create and manage mining pool accounts programmatically. **Account creation:** * Create named mining accounts with optional referral codes * Unique account names with alphanumeric and underscore support * Automatic validation for duplicate names **Account listing:** * Retrieve all mining accounts or filter by name * Results sorted by creation date (newest first) All endpoints require the MINING\_POOL feature to be enabled on the API key. ## API Documentation Updates **Sub-account transfer endpoints: add transactionId for correlation** The response of `/api/v4/sub-account/transfer` and `/api/v4/sub-account/transfer/history` includes the `transactionId` field. Use `transactionId` to correlate transfer operations with transfer history records. The `id` field in transfer history is deprecated. Replace `id` with `transactionId`. ## Documentation Updates **Clarified Book Ticker stream update interval** Refined the description of the Book Ticker WebSocket stream to explicitly state instant BBO snapshot with incremental updates. ## Flex Earn Endpoints **Introduced Smart Flex private endpoints** Added documentation for Smart Flex (Flex Earn) endpoints: list plans, manage investments, view histories, and configure auto-reinvestment. ## API Documentation Updates **Enhanced Query executed orders documentation** Updated documentation for `/api/v4/trade-account/order/history` endpoint to clarify date range filtering capabilities with `startDate` and `endDate` parameters. ## Public API Update **New Funding History endpoint** Added new endpoint `/api/v4/public/funding-history/{market}` to retrieve funding rate history for futures markets. ## Private API Update **Issue JWT Token for Private API** New endpoint to issue JWT token for private API access. **Issue card token using JWT** New endpoint to issue a card token using JWT for secure transactions. **Withdraw endpoint update** Address now accepts card tokens for withdrawals. ## Public WebSocket Update **Added BookTicker WebSocket stream** New bookTicker stream added to WebSocket API, providing real-time updates of best bid/ask prices and quantities for markets. Includes subscription (bookTicker\_subscribe) and unsubscription (bookTicker\_unsubscribe) methods for managing the data feed. ## Trade Engine Update **Event time and update id introduced in WebSocket events** WebSocket events now include `event_time` and `update_id` fields. The `event_time` field provides the timestamp of the event, while the `update_id` field is a unique identifier for each update, allowing for better tracking and synchronization of events. **Hedge mode support** The Hedge mode is now available for all users. This mode allows holding both long and short positions in the same asset simultaneously, providing greater flexibility in managing trades. **Queries Limited to the Last 6 Months** To enhance performance and focus on the most relevant data, the API limits data queries to the past 6 months. Data can be retrieved up to six months old from the current date. ## Withdraw update **HTTP Main V4 API - Withdraw** The `paymentDescription` field is now mandatory for withdrawal requests from whitebit-tr.com. ## Travel Rule Update **HTTP Main V4 API - Travel Rule** Added new statuses DEPOSIT\_TRAVEL\_RULE\_FROZEN (27) and DEPOSIT\_TRAVEL\_RULE\_FROZEN\_PROCESSING (28) to the deposit endpoint. ## Convert History Update **HTTP Trade V4 API - Convert** Added 30 days date range limit for convert history and default values for `from` and `to` parameters. ## Deposit and Withdrawal Updates **HTTP Main V4 API - Birth Date Addition** Added beneficiary.birthDate field (Format: YYYY-MM-DD) to withdrawal requests and customer.birthDate (Format: YYYY-MM-DD) to deposit requests.
