# Impact Migration of POST/v2/proposals/{proposal\_id}/alternative\_transports to POST /v0/proposals/{proposal\_id}/available\_transports

Upgrade from `POST/v2/proposals/{proposal_id}/alternative_transports` to POST `/v0/proposals/{proposal_id}/available_transports`

POST `/v0/proposals/{proposal_id}/available_transports` endpoint body is exactly the same as `POST/v2/proposals/{proposal_id}/alternative_transports`.

ℹ️ In the Response -> a new boolean has been added "is\_applied\_transportation"

⚠️ This new endpoint will always retrieve the proposal's already applied transportation in addition to alternative transports available.

## Impacts

Call  `POST /v0/proposals/{proposal_id}/available_transports` instead of `POST/v2/proposals/{proposal_id}/alternative_transports`
