Constructing a Request
The basic elements of a request to the Fleet Telematics Waypoints Sequence are the start point, a number of destination points and the routing mode.
You can include an end point for sequence optimization, you must provide an end point for pickup along route. If the request does not contain an end point, one of the destination points you provide are chosen. Each point defining the start, a destination or the end consist of WaypointId, latitude and longitude in the WGS 84 system. For more information about the format, see WaypointWithIdType.
Using the parameter improvefor, you can define if to minimize the travel time or travel distance .
mode indicates whether the result is suitable for a car or a truck and whether to use traffic information when processing the request. In addition, mode defines whether single interconnections are fastest or shortest. This setting is important for interaction with the routing APIs. We recommend fastest for most use cases. Be sure to provide a time for the departure if you enable traffic.
For authentication, the parameters app_id and app_code are mandatory. See also Acquiring Credentials.
