origin
Type:  string|LatLng|Place|LatLngLiteral
Location of origin. This can be specified as either a string to be geocoded, or a LatLng, or a Place. Required.
travelMode
Type:  TravelMode

Whether or not route alternatives should be provided. Optional.
region optional
Type:  string optional
Region code used as a bias for geocoding requests. The region code accepts a ccTLD ("top-level domain") two-character value. Most ccTLD codes are identical to ISO 3166-1 codes, with some notable exceptions. For example, the United Kingdom's ccTLD is "uk" (.co.uk) while its ISO 3166-1 code is "gb" (technically for the entity of "The United Kingdom of Great Britain and Northern Ireland").
transitOptions optional
Type:  TransitOptions optional
Settings that apply only to requests where travelMode is TRANSIT. This object will have no effect for other travel modes.
unitSystem optional
Type:  UnitSystem optional
Default: The unit system used in the country of origin.
Preferred unit system to use when displaying distance.
waypoints optional
Type:  Array<DirectionsWaypoint> optional
Array of intermediate waypoints. Directions are calculated from the origin to the destination by way of each waypoint in this array. See the developer's guide for the maximum number of waypoints allowed. Waypoints are not supported for transit directions. Optional.

A DirectionsWaypoint represents a location between origin and destination through which the trip should be routed.

location optional
Type:  string|LatLng|LatLngLiteral|Place optional
Waypoint location. Can be an address string, a LatLng, or a Place. Optional.
stopover optional
Type:  boolean optional
Default: true
If true, indicates that this waypoint is a stop between the origin and destination. This has the effect of splitting the route into two legs. If false, indicates that the route should be biased to go through this waypoint, but not split into two legs. This is useful if you want to create a route in response to the user dragging waypoints on a map.

DirectionsGeocodedWaypoint interface

google.maps.DirectionsGeocodedWaypoint interface

A single geocoded waypoint.

partial_match optional
Type:  boolean optional
Whether the geocoder did not return an exact match for the original waypoint, though it was able to match part of the requested address.

Type:  string optional
The place ID associated with the waypoint. Place IDs uniquely identify a place in the Google Places database and on Google Maps. Learn more about Place IDs in the Places API developer guide.
types optional
Type:  Array<string> optional
An array of strings denoting the type of the returned geocoded element. For a list of possible strings, refer to the Address Component Types section of the Developer's Guide.

DirectionsRoute interface

google.maps.DirectionsRoute interface

A single route containing a set of legs in a DirectionsResult. Note that though this object is "JSON-like," it is not strictly JSON, as it directly and indirectly includes LatLng objects.

bounds
Type:  LatLngBounds
The bounds for this route.
copyrights
Type:  string
Copyrights text to be displayed for this route.
legs
An array of DirectionsLegs, each of which contains information about the steps of which it is composed. There will be one leg for each stopover waypoint or destination specified. So a route with no stopover waypoints will contain one DirectionsLeg and a route with one stopover waypoint will contain two.
overview_path
Type:  Array<LatLng>
An array of LatLngs representing the entire course of this route. The path is simplified in order to make it suitable in contexts where a small number of vertices is required (such as Static Maps API URLs).
overview_polyline
Type:  string
An encoded polyline representation of the route in overview_path. This polyline is an approximate (smoothed) path of the resulting directions.
summary
Type:  string
Contains a short textual description for the route, suitable for naming and disambiguating the route from alternatives.
warnings
Type:  Array<string>
Warnings to be displayed when showing these directions.
waypoint_order
Type:  Array<number>
If optimizeWaypoints was set to true, this field will contain the re-ordered permutation of the input waypoints. For example, if the input was:
  Origin: Los Angeles
  Waypoints: Dallas, Bangor, Phoenix
  Destination: New York
and the optimized output was ordered as follows:
  Origin: Los Angeles
  Waypoints: Phoenix, Dallas, Bangor
  Destination: New York
then this field will be an Array containing the values [2, 0, 1]. Note that the numbering of waypoints is zero-based.
If any of the input waypoints has stopover set to false, this field will be empty, since route optimization is not available for such queries.
fare optional
Type:  TransitFare optional
The total fare for the whole transit trip. Only applicable to transit requests.

DirectionsLeg interface

google.maps.DirectionsLeg interface

A single leg consisting of a set of steps in a DirectionsResult. Some fields in the leg may not be returned for all requests. Note that though this result is "JSON-like," it is not strictly JSON, as it directly and indirectly includes LatLng objects.

end_address
Type:  string
The address of the destination of this leg. This content is meant to be read as-is. Do not programmatically parse the formatted address.
end_location
Type:  LatLng
The DirectionsService calculates directions between locations by using the nearest transportation option (usually a road) at the start and end locations. end_location indicates the actual geocoded destination, which may be different than the end_location of the last step if, for example, the road is not near the destination of this leg.
start_address
Type:  string
The address of the origin of this leg. This content is meant to be read as-is. Do not programmatically parse the formatted address.
start_location
Type:  LatLng
The DirectionsService calculates directions between locations by using the nearest transportation option (usually a road) at the start and end locations. start_location indicates the actual geocoded origin, which may be different than the start_location of the first step if, for example, the road is not near the origin of this leg.
steps
An array of DirectionsSteps, each of which contains information about the individual steps in this leg.
traffic_speed_entry
Type:  Array<?>
Information about traffic speed along the leg.
via_waypoints
Type:  Array<LatLng>
An array of non-stopover waypoints along this leg, which were specified in the original request.

Deprecated in alternative routes. Version 3.27 will be the last version of the API that adds extra via_waypoints in alternative routes.

When using the Directions Service to implement draggable directions, it is recommended to disable dragging of alternative routes. Only the main route should be draggable. Users can drag the main route until it matches an alternative route.

departure_time optional
Type:  Time optional
An estimated departure time for this leg. Only applicable for TRANSIT requests.

If both the placeId and query are provided, an error occurs.
