To request a public transport route using the CalculateRouteRequest service, you must specify the start (waypoint0) and destination (waypoint1) waypoints and choose a public transport routing mode.

Additionally, you must include your authentication credentials, an apiKey or app_id and app_code if you are using the app_id/app_code authentication (see Acquiring Credentials) with each request to the Routing API.

This request queries a route using estimated public transport and specifies a walk radius (in meters) used for finding public transport stations at the start and end of the route. The resulting calculation does not consider transit stations farther away from the start and end points of the route. For documentation on request parameters, see Calculate Route.
