Optimize delivery routes for a fleet using the Routific Engine API

Steps

1. Obtain a Routific API key and include it in every request as the Authorization: Bearer YOUR_API_KEY header with Content-Type: application/json.
2. For jobs with 60 or fewer stops, POST your fleet and visit data to https://api.routific.com/v1/vrp; for larger jobs use https://api.routific.com/v1/vrp-long to avoid timeouts.
3. Structure the request body with a visits object (keyed by stop ID, each with location lat/lng and optional time_window start/end, duration, and load) and a fleet object (keyed by vehicle ID, each with start/end location and optional shift times and capacity).
4. For vrp-long, the response returns a job_id; poll GET https://api.routific.com/v1/jobs/{job_id} at intervals (default 1000 ms) until status is finished.
5. Parse the solution object: each vehicle key maps to an ordered array of stops with arrival_time, finish_time, and any unserved visits; surface unserved stops for manual reassignment.
6. Push the optimized stop sequence back to your dispatch system or delivery app for driver navigation; re-submit to /vrp-long with updated inputs if real-time changes occur during the day.
