hi @elisa.zoom  
thank you for reply! i tried our new api call with reference to [this](https://marketplace.zoom.us/docs/guides/stay-up-to-date/announcements/#send-access_token-in-authorization-header-not-as-query-parameter) but finally got **an `unsupported_grant_type` error** … (same error as [this](https://devforum.zoom.us/t/oauth-app-unsupported-grant-type/79688))  
Here is our api call 👇

```auto
POST https://zoom.us/oauth/token

# Header
Authorization: Basic ${base64 encoded from zoom app client id & client secret }
Content-Type: application/x-www-form-urlencoded

# Request body
refresh_token: ${refreshToken}
grant_type: refresh_token

```

How can we fix it? or isn’t the new api call available yet?
