FAQ

An invoice stays pending until a matching transfer is observed. Confirmations are required before it can become paid. The wrong amount becomes underpaid or overpaid after confirmation, and excess funds are not refunded automatically. Confirmed funds can be withdrawn with POST /v1/withdrawals.

If the invoice expires first, a later payment is stored and the invoice moves to needs review. Supported developer testing is BSC testnet only. Mainnet is not implied to work while the launch gates are open.
