In some cases it may be necessary for you to specify more than 25 waypoints for your routing.
With PTV Developer, there is currently a limit of 25 waypoints per request. (For more information on the limitations, click here).
In order to be able to calculate routes with more than 25 waypoints, you must split your route and rejoin it at the end. For example, you can perform the following calculation:
Request 1: Waypoint 1 - 12
Request 2: Waypoint 12 - 27
Request 3: Waypoint 27 - 35
and so on
At the end of these requests, you can merge them into a complete route.
Additionally we added some CalculateRoutePost request where you are able to add more than 25 waypoints to your request.
