The Portal SOAP API is a legacy web service that provides access to LANDATA property and land registry services. This API uses SOAP/XML messaging over HTTP with WS-Security for authentication.
While SERV is transitioning to modern REST APIs (see Discovery API and Orders API), the Portal SOAP API remains available for existing integrations and provides access to functionality not yet available in the REST APIs.
The Portal SOAP API provides access to:
- Notifications - List and view property alerts and notices for subscriptions
- Certificates - Order and manage property certificates from various authorities
- Property Packages - Order bundled property information packages
- Subscription Management - Manage alert subscriptions and notifications
The Portal service exposes the following SOAP operations:
| Operation | Description |
|---|---|
NotificationList | Retrieve a list of notifications for a subscription |
NotificationView | View details of a specific notification |
AlertSimulate | Simulate an alert for testing purposes |
NoticeSimulate | Simulate a notice for testing purposes |
PackageOrder | Start a property package order |
PackageOrderRestart | Restart an incomplete package order |
PackageCommit | Commit and finalise a package order |
SwitchCertificates | Change certificate selections for an order |
GetOCManagerData | Get certificate manager configuration data |

| Environment | Endpoint |
|---|---|
| Test | https://test.portal.landata.vic.gov.au/Portal/WebServices/Portal.svc |
| Production | https://portal.landata.vic.gov.au/Portal/WebServices/Portal.svc |
For new integrations, consider using the modern REST APIs which offer simpler authentication and easier integration:
- Discovery API - Search for properties, parcels and titles
- Orders API - Place and manage orders for property products
