Datasets available through the Shared Location Information Platform (SLIP) are uploaded via the data upload tool (DUT). DUT has its own Application Programming Interface (API) that provides the date and time of the last successful upload of active datasets.
The API can be called with an HTTP GET request. Data WA uses this API to automatically update the "Data last updated" field for SLIP datasets listed on data.wa.gov.au.
The API is currently an open API that requires no authentication or API Key.
