Response

HTTP Status Code: 200

The response body is the OrderOut order model (see "General Information") with the paymentPageURL field - the URL of the payment page for the payment. The order type is QuasiEcom, the direction is PayIn:

{
  "id": "9c37e448-84b5-4639-9ffa-29558f8f2567",
  "createdAt": "2026-08-31T16:08:06.310479Z",
  "updatedAt": "2026-08-31T16:08:06.310479Z",
  "type": "QuasiEcom",
  "direction": "PayIn",
  "status": "created",
  "merchantOrderID": "316b6280-d6e2-4627-bacd-fcda062438bc",
  "clientID": "ID1234",
  "methodID": 12,
  "currencyCode": "AZN",
  "amount": 100.12,
  "exchangeRate": 1.78,
  "trafficType": "mixed",
  "paymentPageURL": "https://<host>/pay/9c37e448-84b5-4639-9ffa-29558f8f2567"
}

The order is created with the created status; the amountUSDT, merchantCommission, and merchantCommissionUSDT fields are filled after the order is calculated (see "General Information").

Possible business failures (400/409) - see the errorCode table on the "Request Authorization" page.

Callback Conditions

The webhook is sent when the order transitions to one of the trigger statuses. The full list is on the "Callbacks" page.
