This page covers how WIPO DAS reports a result to an OSF over the push-notification webhook.

When this applies

Only when the OSF is configured for API-based exchange and has registered a notification URL with DAS Support. If not, the OSF must poll instead — see 5.1.3.- Responses from DAS to OSF via GET.

Payload shape

{
  "systemId": "WIPO_DAS",
  "notificationCategory": "available",
  "dateTime": "2026-10-19T10:00:00.000Z",
  "totalQuantity": 1,
  "documentRetrievalRequestStatusBag": [
    {
      "requestAckId": "USIB20260101010101",
      "requestStatusCategory": "success | pending | error",
      "errorCode": "numeric code, only present for errors",
      "statusMessage": "human-readable text"
    }
  ]
}

This is the only DAS→OSF channel that carries a numeric error code at all.
