Create Withdrawal

Notes

Withdrawals send coins to a specified address or $PayByName tag over the coin networks and optionally send an IPN when complete.
If you are sending to another CoinPayments user and you have their $PayByName tag or merchant ID you can also use 'create_transfer' for faster sends that don't go over the coin networks when possible.

wdThe withdrawals are passed in an associative array called wd, each having the parameters from 'create_withdrawal' except auto_confirm which is always 1 in mass withdrawals. The key of each withdrawal is used to return the result (same as 'create_withdrawal' again.) The key can contain ONLY a-z, A-Z, and 0-9. Withdrawals with empty keys or containing other characters will be silently ignored.Yes

API Response

A successful call to the 'create_withdrawal' command will give you a result similar to this (JSON):
{
   "error":"ok",
   "result":{
      "id":"hex string",
      "status":0,
      "amount":1.00, // The amount withdrawn
   }
}
The result wil have the following fields:
  • id = The CoinPayments withdrawal ID. (This is not a coin network TX ID.)
  • status = 0 or 1. 0 = Withdrawal created, waiting for email confirmation. 1 = Withdrawal created with no email confirmation needed.
