# Impact migration of the route GET /v1/proposals/{proposal\_id}/transport\_details

## Context

Upgrade from **GET** - `/v1/proposals/{proposal_id}/transport_details` to **GET** -  `/v3/proposals/{proposal_id}/transport_details`

⭐  **Key benefits :** Having the same values in `travel_sections.transport.class`  like all our API endpoints
ℹ️ Values of travel\_sections.transport.class field become: PLANE\_ECONOMY, PLANE\_ECONOMY\_PLUS, PLANE\_BUSINESS, PLANE\_PREMIUM, PLANE\_FIRST, TRAIN\_FIRST, TRAIN\_SECOND instead of ECO, BUS, FIR, 1CL, 2CL, EC+, DIB, DIV, PCR, PRE

***

> As a BE B2B Dev
> I want to be able to use the same mapping for all transport\_class fields
> In order to avoid multiple mappings for the same fields in several endpoints

***

⭐  **Key benefits :** Having the cancellation\_policy\_type one level lower: under each travel\_section

***

> As a BE B2B Dev
> I want to retrieve the cancellation\_policy\_type of my transportation under each travel\_section
> In order to display it on the front-end

***

## Impacts

Route to call :

* **GET** - `/v3/proposals/{proposal_id}/transport_details`

❗ `travel_sections.transport.class` is a string having a new mapping (new values names): PLANE\_ECONOMY, PLANE\_ECONOMY\_PLUS, PLANE\_BUSINESS, PLANE\_PREMIUM, PLANE\_FIRST, TRAIN\_FIRST, TRAIN\_SECOND

❗ `travel_sections.cancellation_policy_type` is an ENUM \[ AUCUN, THEO, WEBTHEO, NDC ]
