In the API reference of Fleet Telematics it says you can use Here Routing V8 for calculate the route. But when I try to send a request (with origin, destination, transport and obviously the API Key) it always return error 404. Which is the correct way to use the fleettelematics/v8/routes then?

Here is a request make with Here Routing (I removed the API key for the picture):

And this is the same request with Fleet Telematics:

I think what you're looking for is the query parameter "return=polyline". So in your example it would be

https://router.hereapi.com/v8/routes?apiKey={apiKey}&transportMode=truck&origin=52.51375,13.42462&destination=52.52332,13.42&return=polyline

I'm still learning to migrate from v7 to v8 myself, but I figure we could do work this out together, so keep this thread updated if you work it out

  • With router.hereapi works fine, but i want to do it with fleet.Is.Hereapi for getting the tolls in the route, but even adding the return parameters I still getting error 404. – santiago_ca Jun 01 '21 at 14:15
  • @chris does it return the cost-optimized route? if yes, what parameters you are using to get the cost-optimized route? – H_H Jun 14 '21 at 07:58

Fleet Telematics API compiles your changes into routable binary map format. Routing uses these layers on top of the HERE map layers.

Documentation page:
https://developers.here.com/documentation/fleet-telematics/dev_guide/topics/custom-routes.html

also, please review the following example for custom routing using fleet telematics
