Make request to “v2/tour” endpoint
with body:
{“locations”:[{“name”:“00c3c753-52c6-4bed-ab9a-0aacb6879d04”,“lat”:“50.4049728”,“lng”:“30.6115912”,“servicetime”:5,“restrictions”:{“demand”:0}},{“name”:“0”,“lat”:“50.4377164”,“lng”:“30.4996084”,“servicetime”:0,“restrictions”:{“ready”:0,“due”:500,“demand”:0}},{“name”:“1”,“lat”:“49.839683”,“lng”:“24.029717”,“servicetime”:0,“restrictions”:{“ready”:0,“due”:500,“demand”:0}}],“parameters[type]”:“car”,“parameters[rounds]”:2,“parameters[balance]”:0,“parameters[endAtMostDistantLocation]”:false}

And get response with

  1. Remarks - “Infeasible: round 1 is too long”
  2. Point 2 without name

if change due time to less than 500 - works fine.
Questions:

  1. How I can use “Due” parameter more than 500?
  2. Is it some limit on Due parameter?

The route is infeasible. The remarks say that’s due to a round being too long. So the maximum roundtime has been exceeded.

The max roundtime limits the duration of each round when creating multiple rounds in a route. By default the max roundtime is 540 minutes (9 hours). Your second round however takes >800 minutes, so the result is infeasible.

To increase the max roundtime in API v2 you can use parameters[maxRoundtime]=x with x being the max roundtime in minutes.

Ps. the point without name is the second location in your input with name “0”, which is zero and translates to null.
