Directions API

Directions API allows you to build a route from point A to point B.

Directions API supports the following types of routes:

an optimal car route considering current or statistical traffic conditions
a shortest possible car route without taking traffic conditions into account
a car route avoiding certain types of roads, like toll roads or dirt roads
a car route that includes public transport lanes (a taxi route)
a pedestrian route including crosswalks and avoiding obstacles
a pedestrian route inside buildings with floor plans
a bicycle route including pedestrian crossings and optionally avoiding stairways, overpasses, underpasses, and highways
a route with intermediate points (up to 10, including start and end point)

For each route, Directions API can additionally return the following information:

altitude information (height above sea level and elevation changes)
information about special points on the route (for example, start of a toll road)

To build a route for a truck, use Truck Directions API.

Getting an access key

Usage of this API requires an API key. To obtain the key, fill out the form at dev.2gis.com/order.

Request example

To calculate a route, send a POST request to the /carrouting/6.0.0/global endpoint. Specify your API key as the key parameter in the query string.

https://routing.api.2gis.com/carrouting/6.0.0/global?key=API_KEY

Coordinates for the route and other parameters must be sent as a JSON string in the request body.

For example, to build a car route from point A to point B considering the current traffic condition, you can send a request similar to the following:

curl --request POST \
 --url 'https://routing.api.2gis.com/carrouting/6.0.0/global?key=API_KEY' \
 --header 'Content-Type: application/json' \
 --data '{
   "locale": "en",
   "points": [
       {
           "type": "walking",
           "x": 82.93057,
           "y": 54.943207
       },
       {
           "type": "walking",
           "x": 82.945039,
           "y": 55.033879
       }
   ]
}'

The points parameter is an array of route points (x is the longitude of a point; y is the latitude of a point). The first element of the array is the starting point.

Response example

The response will return an object containing the information about the calculated route: route length in meters (total_distance), travel time in seconds (total_duration), a list of maneuvers (maneuvers), and other fields. You can find information about each field in API Reference.
