Get route shape

To obtain the shape of a route, specify return=polyline in your route request.

This will result in a polyline field in each section. This polyline is encoded using a flexible polyline. You can encode this polyline easily in many major languages using examples available in the flexible polyline repository.

Maps API for Javascript provides wrappers which can do the decoding for you. Please see the JS API Routing example on how the flexible-polyline is used.

You can also use

curl -X GET \
  'https://router.hereapi.com/v8/routes?transportMode=car&origin=52.5308,13.3847&destination=52.5323,13.3789&return=polyline&apikey={YOUR_API_KEY}'
