This endpoint authorizes the irreversible transfer of cryptocurrency held in Binance escrow directly to the buyer's funding wallet. It represents the final operational step in a P2P sell order workflow, transitioning the order status from BUYER_PAYED to COMPLETED.

Automated payout bots, merchant payment gateways, and high-frequency P2P settlement engines invoke this endpoint programmatically along with 2FA/MFA verification factors once inbound bank transfers or mobile money receipts are confirmed. For a complete implementation example, check out our guide on
