The Trimble Trip Management Modify Trip API allows developers to update a previously generated route. This API's fields can be used to replace the corresponding fields in existing trips. If a trip is in-progress, developers cannot modify the planned start time or location, vehicle, routing profile, or stops that have been completed. Trips that have been completed or canceled cannot be modified with this API.
This API is one of many routing, location, and mapping APIs provided by Trimble.
