# Migration of the route  GET /v3/proposals/{proposal\_id}/transport\_details to the route  GET /v4/proposals/{proposal\_id}/transport\_details

## Context

Upgrade from **GET** - `​ GET /v3/proposals/{proposal_id}/transport_details` to **GET** -  `​ GET /v4/proposals/{proposal_id}/transport_details`

⭐  **3 Key benefits :**

* Add a new field `unit` to precise the luggage weight unit
* No longer display the weight unit of the luggage
* The luggage unit will now be specific to each locale, by default it is KG

## Impacts

Route to call :

* **GET** -  `​ GET /v4/proposals/{proposal_id}/transport_details`
