幣安槓桿為所有全倉和逐倉用戶提供兩個不同的下單交易介面：
- POST /sapi/v1/margin/order
- POST /sapi/v1/margin/order/oco
其中參數sideEffectType為訂單介面設定以下四種交易模式：
- NO_SIDE_EFFECT（普通模式）： 直接使用槓桿賬戶內的現有數字資產下買/賣單。這種模式下，用戶需要在槓桿平台上手動借款/還款，或通過 POST /sapi/v1/margin/borrow-repay 借款/還款。
- MARGIN_BUY（自動借款模式）：根據用戶的最大槓桿倍數，自動借入數字資產下買/賣單。簡而言之，相當於「借款 + 下單」。注意：下單成功即完成借款，借款與訂單成交沒有關係。
- AUTO_REPAY（自動還款模式）：買/賣單成交後，系統自動使用收到的數字資產來償還該資產的負債。簡而言之，相當於「下單 + 訂單成交 + 還款」。還款依然遵循借什麼還什麼，先還利息再還本金的原則。
- AUTO_BORROW_REPAY（同時自動借款和還款）：用户在下單時，結合MARGIN_BUY 和 AUTO_REPAY兩種模式，完成「借款 + 下單 + 訂單成交 + 還款」。
參數sideEffectType設定不同交易模式舉例：
