Showing directions output as leaflet geoJson layer


I was looking at the documentation for and on that page you also show the response of the API on a map by using the leaflet library. I am trying to do the same thing, but don’t know how to get from the response of the directions API to the map. The API documentation says the response is in geoJson format, but just putting the response (body) into a leaflet L.geoJSON(response).addTo(map); gets me a “Error: Invalid GeoJSON object.” Any help on how to work the API response into leaflet would be much appreciated.


The directions response is by default encodedpolyline (as per our docs).

If you specifiy format=geojson, you get a GeoJSON response.


Thank you, that helped a lot.

The main description for get directions in the docs reads: “Returns a route between two or more locations for a selected profile and its settings as GeoJSON response.” … maybe that should be changed to avoid confusion.

Best wishes,



I’m having the same problem as above (“Error: Invalid GeoJSON object”). Where can i insert the statement “format=geojson” ?


let request = new XMLHttpRequest();‘POST’, “”);

request.setRequestHeader(‘Accept’, ‘application/json, application/geo+json, application/gpx+xml, img/png; charset=utf-8’);
request.setRequestHeader(‘Content-Type’, ‘application/json’);
request.setRequestHeader(‘Authorization’, ‘---------------------------’);

request.onreadystatechange = function () {
if (this.readyState === 4) {
console.log(‘Status:’, this.status);
console.log(‘Headers:’, this.getAllResponseHeaders());
console.log(‘Body:’, this.responseText);

const body = ‘{“coordinates”:[[8.889055,44.418111],[8.944448,44.404032]],“attributes”:[“detourfactor”,“percentage”],“extra_info”:[“steepness”,“waytype”,“surface”],“instructions”:“true”,“format”:“geoJSON”,“language”:“it”,“options”:{“avoid_polygons”:{“type”:“Polygon”,“coordinates”:[[[“8.90115”,“44.41618”],[“8.92476”,“44.42204”],[“8.91875”,“44.40594”],[“8.90115”,“44.41618”]]]},“vehicle_type”:“hgv”},“preference”:“fastest”,“units”:“km”,“geometry”:“true”}’;





Change the URL. And read the docs;){profile}/geojson/post


Sorry, but that was not helpful to me.

I’m having the same problem and I have a different URL.‘POST’, “”);

Is it even possible to just print it to the map with just


Then it’s best if you explain what’s not working for you, i.e. the exact request incl POST parameters and headers and the response.


This the code I have so far. I tried a bunch of different variables for ??? but nothing worked. I also couldn`t find an example on how to show the route in leaflet anywhere.

let request = new XMLHttpRequest();'POST', "");

request.setRequestHeader('Accept', 'application/json, application/geo+json, application/gpx+xml, img/png; charset=utf-8');
request.setRequestHeader('Content-Type', 'application/json');
request.setRequestHeader('Authorization', '5b3ce3597851110001cf624867f677852d8b48b5ad3a20d0c1932a8e');

request.onreadystatechange = function () {
  if (this.readyState === 4) {
    console.log('Status:', this.status);
    console.log('Headers:', this.getAllResponseHeaders());
    console.log('Body:', this.responseText);


const body = '{"coordinates":[[11.0419554,49.5939908],[11,49.6],[11.0393399,49.594125]],"attributes":["detourfactor","percentage"]}';



That’s a very basic programming error. Please use Stack Overflow to resolve.

You’re not referencing the response of the web request anywhere. Refer to XMLHttpRequest documentation. Somewhere you’ll send a request and get back an object, which contains the response (likely .send). Or use some friendlier library like axios.


Hey @Ann,
If you want to use ors with javascript you might want to use our openrouteservice-js it should provide the same functionality you seek and you might find it easier to use.
