Fixed by using the follow query parameters: ?grant\_type=account\_credentials&account\_id={account\_id}{account\_id} can be found by making a GET request [https://api.zoom.us/v2/accounts](https://api.zoom.us/v2/accounts)

See [Getting Account ID for server-to-server OAuth](https://devforum.zoom.us/t/getting-account-id-for-server-to-server-oauth/70559)
