Start a new navigation session
After creating a new route and obtaining your route id, you can use the startNavigation mutation to start a new navigation session. A navigation session is automatically finished after 48 hours of inactivity. During that time frame you can subscribe to it for updates or query its current state.
Mutation
To start a navigation session, you need a route id, an alternative_id, your current_location and the instructions input. Of these four arguments alternative_id is optional. In case no alternative was chosen explicitly the first route is used for the navigation session. In order to start a navigation session you need to be in proximity of the route.
