Important Notes

• ExternalId Uniqueness: The ExternalId must be unique per transaction in your system. It is used for idempotency — submitting the same ExternalId twice will return the existing transaction data instead of creating a duplicate.

• txId Availability: For on-chain withdrawals, txId is null while the transaction is pending. It is populated once the transaction is broadcast to the blockchain.

• binanceId in Response: The binanceId in the withdrawal response becomes available after Binance processes the request. It is null immediately after creation.

• Currency format for on-chain: Always use the exact name returned by /BinanceOnchainWithdrawCoins in the Currency field — including the network suffix, e.g. USDT (BEP20).

• Deposit flow: After calling /binancepaydeposit, redirect the client to the url field or display the qrLink. The client must complete payment in the Binance app.
