OnLink
API reference

Your USDT holding wallet

The wallet that holds your USDT, and what USDT sent to it does. If OnLink holds your USDT for you (custody: onlink_managed) this is your deposit address with OnLink, and USDT sent to it is credited to your USDT balance. If your USDT is in your own wallet (custody: partner_customer) this is that wallet: your sells and sends draw from it. It is not one of the withdrawal wallets you register under /v1/wallets. When no address has been allocated for your account yet the answer is 503 with errorCode HOLDING_WALLET_NOT_ALLOCATED: contact OnLink, you cannot set it up yourself. A Collections credential is refused: that product holds no USDT.

Your USDT balance GET

The USDT you can use now. If OnLink holds your USDT for you (custody: onlink_managed) this is your OnLink USDT ledger: it already excludes USDT committed to a sell order or to a send that has started, and a buy counts once it has been delivered. If your USDT is in your own wallet (custody: partner_customer) it is read from that wallet and may be up to 30 seconds old. When your wallet cannot be read, available is null and unavailableReason names why; it is never reported as 0. A Collections credential is refused: that product holds no USDT.
