Transfers

The transfer method sends money from your app balance to a PS Wallet user by their Telegram ID. The transfer is instant and free of charge: the money arrives in the user's account in the same coin and network. It's convenient for paying out winnings, cashback, refunds, and rewards.

#Before you start

1. Enable the method in your app dashboard: "Security" → "Transfers to users via API" (you'll need your PIN). The method is disabled by default, and a request will return the error 403 METHOD_DISABLED.
2. Top up your app balance: paid invoices are credited to it automatically, and you can also top it up from your own account in the dashboard — free of charge.

#transfer

Sends money from the app balance to a PS Wallet user. POST only. Returns Transfer.

If you specify asset=USDT, the money is debited from the first network where the app balance has enough funds: TRC20 → BEP20 → TON → ERC20. The transfer network is returned in the asset field of the response.

#Request example

curl https://pay.pswallet.org/api/transfer \
  -H "PSWallet-Pay-API-Token: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "user_id": 123456789,

    "comment": "Выигрыш в розыгрыше"
  }'

// Node.js 18+ (built-in fetch)
// Generate spend_id once and save it before sending the request
const spendId = `prize-${drawId}-${userId}`;

  }
}

#Double sending and timeouts

spend_id is your transfer key. Generate it once for each payout (for example, from the order or payout number) and save it before sending the request. A repeated request with the same spend_id will not transfer the money a second time and will return the error SPEND_ID_USED.

#Comment and notification

• The recipient receives a notification in the PS Wallet bot unless disable_send_notification=true is passed.
• The recipient will see the comment in the notification and history only if the transfer amount is not below the threshold (default $1). Below the threshold, the transfer goes through without your text.
• Links and @mentions in the comment the recipient sees are replaced with […]. In the API response and in getTransfers, the comment is returned exactly as you sent it.

#transfer errors

#getTransfers

A list of the app's transfers, newest first. Returns { "items": [Transfer, …] }.

curl "https://pay.pswallet.org/api/getTransfers?spend_id=prize-2026-11-09-123456789" \
  -H "PSWallet-Pay-API-Token: $TOKEN"

Response:

{
  "ok": true,
  "result": {
    "items": [
      {
        "transfer_id": 311,
        "spend_id": "prize-2026-11-09-123456789",
        "user_id": "123456789",
        "asset": "USDT-TRC20",
        "amount": "5",
        "status": "completed",
        "completed_at": "2026-11-09T12:00:00.000+00:00",
        "comment": "Выигрыш в розыгрыше"
      }
    ]
  }
}

An empty items when searching by spend_id means the transfer didn't happen — you can send it again with the same spend_id.

Errors (code 400): PARAM_ASSET_INVALID, PARAM_TRANSFER_IDS_INVALID, PARAM_OFFSET_INVALID, PARAM_COUNT_INVALID.
