Migration from V2 - Solvice Docs

Overview

The V3 Routing API is a ground-up rewrite with a new, faster solver engine replacing Timefold. The V2 endpoint (/v2/vrp/sync/solve) remains available for backwards compatibility — internally it maps to V3 and back.

Endpoint change

	V2 (OnRoute)	V3 (Routing)
URL	`POST /v2/vrp/sync/solve`	`POST /v3/routing/solve`
Auth	`Authorization: API_KEY`	`Authorization: API_KEY`
Coordinate format	`{"latitude": 50.85, "longitude": 4.35}`	`{ "coordinate": [4.35, 50.85] }` (GeoJSON: lon, lat)
Time format	ISO 8601 strings	ISO 8601 strings
Field naming	camelCase	snake_case

Request mapping

Vehicles (Resources → Vehicles)

{
  "name": "truck-1",
  "shifts": [
    {
      "from": "2026-04-01T08:00:00+02:00",
      "to": "2026-04-01T17:00:00+02:00",
      "start": { "latitude": 50.8503, "longitude": 4.3517 },
      "end": { "latitude": 50.8503, "longitude": 4.3517 }
    }
  ],
  "capacity": [100],
  "tags": ["refrigerated"]
}

{
  "id": "truck-1",
  "capacity": { "weight": 100 },
  "skills": ["refrigerated"],
  "shifts": [
    {
      "from": "2026-04-01T08:00:00+02:00",
      "to": "2026-04-01T17:00:00+02:00",
      "start": { "coordinate": [4.3517, 50.8503] },
      "end":   { "coordinate": [4.3517, 50.8503] }
    }
  ]
}

Key differences:

name → id
shifts[].start/end move to inside shifts[] as a Place ({ "coordinate": [lon, lat] }) — this is still inside the shift in both V2 and V3, but the coordinate format changes
Coordinates: { "latitude", "longitude" } object → { "coordinate": [longitude, latitude] } Place (GeoJSON order, wrapped in object)
capacity: array [100] → named map { "weight": 100 } (dimension names must match job demand keys)
tags → skills (note: V2 tags are not automatically mapped when using the V2 compat endpoint)
New: limits.max_distance_m, limits.max_drive_time_s for vehicle range constraints

Jobs

{
  "name": "delivery-1",
  "location": { "latitude": 50.8798, "longitude": 4.7005 },
  "duration": 300,
  "load": [10],
  "windows": [
    {
      "from": "2026-04-01T09:00:00+02:00",
      "to": "2026-04-01T12:00:00+02:00",
      "hard": true
    }
  ]
}

{
  "id": "delivery-1",
  "location": { "coordinate": [4.7005, 50.8798] },
  "service_duration_s": 300,
  "demand": { "weight": 10 },
  "time_windows": [
    {
      "from": "2026-04-01T09:00:00+02:00",
      "to": "2026-04-01T12:00:00+02:00"
    }
  ]
}

Key differences:

name → id
location: { "latitude", "longitude" } → Place object { "coordinate": [longitude, latitude] }
duration → service_duration_s (still in seconds)
load array → demand named map (e.g. [10] → { "weight": 10 })
windows → time_windows (no hard flag — all time windows are hard in V3 Phase 1)
Skills and committed vehicle: skills: [{ "name": "refrigerated" }], eligible_vehicles: { "allowed": ["truck-1"] } — Coming soon (Phase 2)

Relations

V3 uses a tagged-union format with job_ids (not jobs). V2 relation types map as follows:

V2 `type`	V3 `type`	Notes
`SEQUENCE`	`ordered`	`job_ids` instead of `jobs`; `resource` pin not yet supported
`FIRST_JOB`	`ordered` with a single entry in `job_ids`	Pin job to position 1 in route

{
  "type": "SEQUENCE",
  "jobs": ["job-A", "job-B", "job-C"],
  "resource": "truck-1"
}

{
  "type": "ordered",
  "job_ids": ["job-A", "job-B", "job-C"]
}

Note: V2’s resource field (pin relation to a specific vehicle) is not yet supported in V3. Use eligible_vehicles on individual jobs as a workaround — Coming soon.

Options

{
  "solvingTime": 30
}

{
  "options": {
    "runtime": {
      "time_limit_ms": 5000,
      "seed": 42
    }
  }
}

Key differences:

solvingTime (seconds) → options.runtime.time_limit_ms (milliseconds)
New: options.runtime.seed for reproducible results
New: options.runtime.matrix — supply custom distance/duration matrices (bypasses Solvice Maps)
Objective tuning (minimize time vs. distance) is configured via the objective field — Coming soon

        }
      ]
    }
  ],
  "unassigned": []
}

Key differences:

trips → routes; resource → vehicle object { "type": "truck-1", "instance": 1 }
visits → stops (typed: start, job, end, etc.)
V3 stops carry type, id, arrival, departure, wait_s, service_s, travel_time_s, load_after (named map)
V3 routes use distance_m / duration_s (not bare distance / duration)
unserved (string list) → unassigned (objects with job_id and reasons[])
New summary block with jobs_assigned/jobs_unassigned, total_distance_m, total_duration_s, estimated_cost, elapsed_ms, iterations
Coordinates in response are bare [longitude, latitude] arrays

V2 features not mapped via compat endpoint

When using the V2 endpoint (/v2/vrp/sync/solve), the following V2 fields are silently dropped during conversion:

resources[].tags — V2 skill tags are not forwarded to the V3 solver
relations[].resource — pinning a relation to a specific vehicle is ignored
windows[].hard — soft time window flag has no V3 equivalent yet
Per-visit serviceTime, travelTime, distance — not populated in the V2 response

Feature parity

V3 currently implements a subset of V2’s features. The rest are on the roadmap.

V3 is under active development. The V2 endpoint (/v2/vrp/sync/solve) remains available and internally maps to the V3 solver — you get V3’s performance with the V2 API contract.
