GTFS-RT APIs (service alerts and trip updates) hosted at api.digitransit.fi have been deprecated. For HSL region, realtime data in GTFS-RT format is available from HSL GTFS-RT API. Realtime data is also available from the routing API.
Realtime APIs provide disruption information and predictions for stop arrival and departure times in GTFS RT format and vehicle positions in a custom JSON format. When using realtime APIs, keep in mind that the availability and quality of the data varies in each city.
At first you should read the real-time API getting started guide to better understand limitations and possibilities.
Note: service alerts and trip updates are incorporated to the routing API. If you are using routing API, there is no need to use GTFS-RT APIs for service alerts and trip updates.
