Freshchat api rejects my token

Hello. I got my token for freshchat from “Personal Settings > API Settings”, but it works for some endpoint and for others it doesn’t.

It works for asd.freshchat.com/v2/users but not for asd.freshchat.com/v2/conversations

The last one, responds with this message:

{
    "error_code": 403,
    "error_message": "javax.security.sasl.AuthenticationException: Auth failure",
    "success": false
}

Thanks
