**Description**  
List users API call returns nothing in Body, with 200 (OK) status.

**Error**  
When sending GET “[https://api.zoom.us/v2/users](https://api.zoom.us/v2/users)”, response has status 200 (OK) but Body is **null**. Account has 7,884 users. Expected JSON data in Body with information for 30 of those users (because page\_size has Default of 30).

**Which App Type (OAuth / Chatbot / JWT / Webhook)?**  
JWT

**Which Endpoint/s?**  
GET /users

**How To Reproduce (If applicable)**  
Steps to reproduce the behavior:

1. Send an HTTP GET request to [https://api.zoom.us/v2/roles](https://api.zoom.us/v2/roles) with appropriate Authorization header
2. Get response with status 200 (OK) and JSON data in Body showing roles. This confirms I am sending the right Authorization header and otherwise using the API correctly.
3. Send an HTTP GET request to [https://api.zoom.us/v2/users](https://api.zoom.us/v2/users) with the same Authorization header as in step 1
4. Get response with status 200 (OK) and **null** Body that should have had JSON data with user information.

Hi @charlene.wright ,

Happy to assist! Can you please share the full request URLs, bodies that you’re sending to these API endpoints and their respective responses? Blur any sensitive, unsharable information.

Thank you,  
Gianni

Gianni,

Thank you for your assistance.

Below is C# console-app code to reproduce my problem, followed by the output. As you can see, the call to /roles returns JSON; while the call to /users returns nothing.

Thanks,

Matt

**Code**

```auto
using Microsoft.IdentityModel.Tokens;
using System;
using System.IdentityModel.Tokens.Jwt;
using System.IO;
using System.Net;
using System.Text;

namespace ZoomUsers
{ // ZoomUsers

  class Program
  { // Program

    static void GetData(string path)
    { // GetData

      const string apiKey = "REDACTED";
      const string apiSecret = "REDACTED";

      string apiUrl = "https://api.zoom.us/v2/" + path;

      Console.WriteLine("Url: " + apiUrl);

      DateTime ZoomApiAuthorizationTokenExpiration = DateTime.UtcNow.AddSeconds(30);

      JwtSecurityTokenHandler tokenHandler = new JwtSecurityTokenHandler();

      string zoomApiAuthorizationToken =
        tokenHandler.WriteToken(
          tokenHandler.CreateToken(

                Issuer = apiKey

                  , SecurityAlgorithms.HmacSha256
                )

        HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(apiUrl);

        webRequest.Method = "GET";
        webRequest.Headers.Add("Authorization", "Bearer " + zoomApiAuthorizationToken);

        IAsyncResult asyncResult = webRequest.BeginGetResponse(null, null);

        asyncResult.AsyncWaitHandle.WaitOne();

          using (HttpWebResponse webResponse = (HttpWebResponse)(webRequest.EndGetResponse(asyncResult)))
          { // using webResponse

            Console.WriteLine("StatusCode: " + webResponse.StatusCode.ToString());
            Console.WriteLine("ContentLength: " + webResponse.ContentLength.ToString());

            if (webResponse.ContentLength > 0)
            { // get response body

              using (StreamReader reader = new StreamReader(webResponse.GetResponseStream()))
              { // using reader
      
                Console.WriteLine("Response: " + reader.ReadToEnd());
      
              } // using reader
    
            } // get response body

          } // using webResponse

          Console.WriteLine();
    
    } // GetData

    static void Main(string[] args)
    { // Main

      GetData("roles");
      GetData("users");

    } // Main

  } // Program

} // ZoomUsers

```

**Output**
