# Upgrade from PUT ​/v0​/proposals​/{proposal\_id}​/accommodations\_arrangement to PUT ​/v1​/proposals​/{proposal\_id}​/accommodations\_arrangement

## Context

A while ago, we worked on enhancing our API backend calls in order to enhance our performances. In order to call the accommodation\_arrangement\_check backend endpoint instead of the moreRooms, we need to add a new body parameter: "occupancy".

Upgrade from **PUT** - `/v0​/proposals​/{proposal_id}​/accommodations_arrangement` to **PUT** -  `/v1/proposals​/{proposal_id}​/accommodations_arrangement`

⭐  **Key benefits :** Having a quicker response time and uniformizing our ressources.

***

> As an API dev
> I want to be able to call `accommodation_arrangement_check` instead of `moreRooms`
> In order to gain in response time
