I have created Server-to-Server-oauth app in marketplace. I’m able to get the token through postman. Trying to get the token through C# code but it is giving ““Request failed with status code NotFound””

var client = new RestClient(“[https://zoom.us/oauth/token?grant\_type=account\_credentials&account\_id={accountId}](https://zoom.us/oauth/token?grant_type=account_credentials&account_id=%7BaccountId%7D)”);  
var request = new RestRequest(Method.Post.ToString());

```
        request.AddHeader("authorization", "Basic {clientId:clientSecret}");
        request.AddHeader("content-type", "application/x-www-form-urlencoded");
         RestSharp.RestResponse response = client.Execute(request);

```

I have used the www.base64encode to generate the string as well. I’m using [ASP.NET](http://ASP.NET) Core Web API. Can you please let me know what is missing here.

Thanks,
