# Migration of the endpoint POST /v4/proposals/{proposal\_id}/transport\_details to POST /v5/proposals/{proposal\_id}/transport\_details

## Context

Upgrade from **POST** - `​/v4/proposals/{proposal_id}/transport_details` to **POST** -  `​/v5/proposals/{proposal_id}/transport_details`

⭐  **2 Key benefits :**

* Get the new `time_validity_limit`  field to retrieve the time validity limit of the current transport (if it exists)
* With the new structure (the whole transport falls into the new "journeys" section), in the future we will be able to add more general fields related to the transport

## Impacts

Route to call :

* **POST** -  `​/v5/proposals/{proposal_id}/transport_details`

## Output
