# 2025-05-12: Customer Service - improvements

## Overview

The token responses was improved with new properties compliant with the OAuth 2.0 specification. Properties from the response `accessToken`, `saasToken`, `expiresIn`, `refreshToken`, `refreshTokenExpiresIn` are now deprecated in favor of the new properties (`access_token`, `saas_token`, `expires_in`, `refresh_token`, `refresh_token_expires_in`, `token_type`).\
All deprecations will be removed on 2025-11-13. From now, use the new token properties.
