FixedOct 13, 2026

Withdrawal webhooks: book outcome.delivered_amount, read progress by reason

Book a closed withdrawal with outcome.delivered_amount, not summary.withdrawer_received. WITHDRAWAL_PARTIALLY_FUNDED now has its reasons documented with real examples.

ImprovedOct 13, 2026

P2P deposit webhooks: silent expiry, credit by payment_amount

An expired P2P deposit no longer sends PAYMENT_CANCELED, and PAYMENT_PAID must be credited with payment.payment_amount.

NewAug 9, 2026

P2P is now supported

Deposits and withdrawals are matched against each other. One transfer, from a depositor straight to your customer, closes both at once and the money never passes through the central account.

NewJun 16, 2026

Withdraw verify — second layer for withdrawals

Two-layer (second) verification for withdrawals — before a withdrawal is created, your backend must confirm it via webhook and return 200.

NewMay 25, 2026

PromptPay fiat withdrawals

Fiat withdrawals can now go to a PromptPay number — just put it in withdrawal_address, no extra field needed.

NewMay 22, 2026

Auto-convert deposits: THB ↔ USDT

Accept a deposit in one currency and be credited in the other automatically at the Binance TH rate — both USDT → THB and THB → USDT.
