Authorizations

X-TXC-APIKEY · string · header · required

The public WhiteBIT API key.

X-TXC-PAYLOAD · string · header · required

Base64-encoded JSON request body.

X-TXC-SIGNATURE · string · header · required

HMAC-SHA512 signature of the payload, hex-encoded. Computed as hex(HMAC-SHA512(payload, api_secret)).

Body

application/json

market · string · required

Available margin market. Example: BTC_USDT

Example:

"BTC_USDT"

side · enum<string> · required

Order direction. Use buy to open or increase a long position and sell to open or increase a short position.

Available options: buy, sell

Example:

"buy"

amount · string · required

Amount of stock currency for both legs of the OCO order. Minimum and step values are market-dependent — query the market info endpoint for constraints.

Example:

"0.001"

price · string · required

Limit order price in money currency for the take-profit leg.

Example:

"40000"

activation_price · string · required

Trigger price in money currency for the stop-loss leg. The stop-limit order activates when the market price reaches the specified value.

Example:

"41000"

stop_limit_price · string · required

Execution price in money currency for the stop-loss leg. After activation, the stop-loss leg places a limit order at the specified price.

Example:

"42000"

request · string · required

Example:

"{{request}}"

nonce · string · required

Example:

"{{nonce}}"

client_order_id · string

Custom order identifier. Must be unique and contain only letters, numbers, dashes, dots, or underscores.

Example:

"order1987111"

reduceOnly · boolean · default: false

When true, both legs of the OCO order can only reduce or close an existing position — neither leg can increase the position or open a new one. If the order amount exceeds the current position size, the system reduces the order to match — the response returns the adjusted amount. The API returns error code 116 if no open position exists or the order side matches the position direction. See reduce-only.

Example:

false
