Hi, @zoom123,

Thank you for posting in the Developer Forum – I am happy to help. Sorry to hear that you getting 400 bad request. Can you try to make the request with the following curl command :

```auto
curl --location --request POST 'https://zoom.us/oauth/token?grant_type=account_credentials&account_id={accountId}' \
--header 'Authorization: Basic Base64Encoder(clientId:clientSecret)' \
--data-raw ''

```

Also, there is a helpful utility script to generate a Zoom Server-to-Server Oauth Token and copy it to the clipboard on our GitHub as well:
