請求格式

地理位置場地必修描述
標頭X-API-KEY是的apiKey 在 API Key 建立時會回傳
查詢timestamp是的Unix 毫秒時間戳記
查詢signature是的HMAC-SHA256 簽名，小寫十六進制字串
車身JSON這取決於終點POST / PUT / DELETE 請求正體

簽名有效載荷

payload = queryStringWithoutSignature + requestBody
signature = HMAC-SHA256(apiSecret, payload)

關鍵規則：

  • timestamp 必須是 Unix 毫秒的時間戳記。伺服器容忍範圍為 ±10 秒。
  • signature 放在 URL 查詢字串中，但不包含在簽章有效載荷中。
  • 伺服器在移除 signature後驗證原始查詢字串;它不會重新排序查詢參數。
  • 用於簽署的查詢參數順序必須與實際請求 URL相符。
  • 若存在請求實體，用於簽署的 JSON 字串必須與實際傳送的實體完全一致。
  • 順序相關路徑會執行簽名重播檢查。在短時間內重複使用相同簽名會返回 Signature replay detected。

伺服器時間

GET /v1/time

回應範例：

{
  "code": 0,
  "message": "success",
  "data": {
    "timestamp": 1780473256,
    "timestampMs": 1780473256708,
    "iso": "2026-06-03T07:54:16Z",
    "timezone": "UTC"
  },
  "requestId": "req-7cad3113"
}

用戶端應計算 timeOffsetMs = serverTimestampMs - localTimestampMs，然後對後續的簽名請求使用 timestamp = nowMs + timeOffsetMs 。若伺服器回傳 Timestamp outside of tolerance window，立即重新同步時間並重新產生簽名。

GET 簽名範例

實際請求：

GET /v1/private/order/current?symbol=BTCUSDT&timestamp=1772710377808&signature=...

特徵有效載荷：

symbol=BTCUSDT&timestamp=1772710377808

POST 簽名範例

實際請求：

POST /v1/private/order/place?timestamp=1772710377808&signature=...

請求正文：

{"symbol":"BTCUSDT","type":"LIMIT","side":"BUY","price":"85000","quantity":"0.1","timeInForce":"GTC","makerOnly":true,"clientOrderId":"ext-1772710377808-001"}

特徵有效載荷：

timestamp=1772710377808{"symbol":"BTCUSDT","type":"LIMIT","side":"BUY","price":"85000","quantity":"0.1","timeInForce":"GTC","makerOnly":true,"clientOrderId":"ext-1772710377808-001"}
