Request Headers:

Authorization: Bearer <access_token>

Content-Type: application/json

Request Body:

{
    "wallet": "<wallet_uuid>", // the source wallet uuid
    "destination" : "TDmx..Fx68" // Only for TRX or USDT withdrawal
    "amount": 20000000 // Only for TRX or USDT amount in SUN based (20 x 1000000)
    "paymentRequest": "LNINVOICE..." // Only for Case of Bitcoin LN Invoice
}

Success Response: If the OTP is enabled (success.data.isOTP: true), broadcasting the transaction will require an OTP to be authorized. Note that 1 TRX = 1000000 SUN. Amounts are denominate in SUN, for both USDT and TRX, which means you have to divide the amounts by 1,000,000 for user presentation.
