Beta notice : this endpoint is part of our v3-suite beta testing phase.
Please note that:

• The behavior and structure may change before public release.
• Some features or results may still be incomplete or evolving.

Retrieve the full details of a saved route snapshot by its id.

Notes and considerations

• id lifetime: the route id remains valid for a limited period (at least 1 hour), following the same policy as other v3/routes sub-resources.
• This endpoint is useful when you have received a snapshot id of a route after posting a shipment (via POST /v3/shipments) and need to fetch its full details without re-creating the route.

Support endpoints and resources

• Search routes: use /v3/routeCollections to search for routes.
