We are using JWT without any issues as the JWT is going to deprecated so we need to shift to OAuth, I am using the following code

var tokenHandler = new System.IdentityModel.Tokens.Jwt.JwtSecurityTokenHandler();  
var now = DateTime.UtcNow;  
var apiSecret = “My Secreat Key”;  
byte symmetricKey = Encoding.ASCII.GetBytes(apiSecret);

```
        var tokenDescriptor = new SecurityTokenDescriptor
        {
            Issuer = "My Issuers Code",
            Expires = now.AddSeconds(300),
            SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(symmetricKey), SecurityAlgorithms.HmacSha256),
        };

        var token = tokenHandler.CreateToken(tokenDescriptor);
        var tokenString = tokenHandler.WriteToken(token);

        var client = new RestClient("https://api.zoom.us/v2/users/milaapmp@gmail.com/meetings");
        var request = new RestRequest("", Method.Post);
        request.RequestFormat = DataFormat.Json;
        request.AddJsonBody(new { topic = "Meeting Topic", duration = "10", start_time = "2023-04-30T18:20:00", type = "2" });

        request.AddHeader("authorization", String.Format("Bearer {0}", tokenString));
        RestResponse restResponse = client.Execute(request);
        HttpStatusCode statusCode = restResponse.StatusCode;
        int numericStatusCode = (int)statusCode;
        var jObject = JObject.Parse(restResponse.Content);

        Host.Text = (string)jObject["start_url"];
        Join.Text = (string)jObject["join_url"];
        Code.Text = Convert.ToString(numericStatusCode);

```

Can I use the same code just change the OAuth Client Key and Secret or any changes, If you have any example of sample code request to share

Thanks

Hi @milaapmp  
Thanks for reaching out to us! I am happy to help here!

The only thing that you need to change is the way yo generate your token.  
For the JWT app, you use your API key and secret to generate a JWT token.

In the case of the Server to Server oauth app, you will need to make a post request to our Oauth endpoint using your client ID, client secret, and account ID, to get the access\_token.

Then that token will be used in the same way that you are currently using it.

Here is a link to our Docs:  
[https://developers.zoom.us/docs/internal-apps/#use-account-credentials-to-get-an-access-token](https://developers.zoom.us/docs/internal-apps/#use-account-credentials-to-get-an-access-token)

Cheers,  
Elisa

Hi Elisa,

Thanks for response, I have used the code to generate the token.

var client = new RestClient(“[Sign In | Zoom](https://zoom.us/oauth/authorize?response_type=code&client_id=iBnqJNr7TvK89qiVAfpLTA&redirect_uri=https%3A%2F%2Fmpmilaap.in%2FCreate)”);  
var request = new RestRequest(“”, Method.Post);  
request.AddHeader(“Authorization”, “HSrRBUOaUTbUL6bV1UXKTGXvgKem5PY2”);

```
        RestResponse response = client.Execute(request);
        Label1.Text = response.Content;

```

I refer the code from the given link below, but the token is not generating, it will shift to zoom

> Hi @mnf, Thanks for reaching out about this. Have you had a chance to look over our OAuth Guide? The first step, if you haven’t already, is to [create an OAuth App](https://marketplace.zoom.us/docs/guides/build/oauth-app) to generate your Client ID and Secret. From there, you will then need to follow steps 1 and 2 in our guide: retrieving the code from your redirect URL after the user installs the app, and then using that code in step 2 to fetch an access token. Your second request (after you retrieve the code), should look something like this: var…

Request to help

Hey @milaapmp  
So your best choice here would be to user our Server to Sever OAuth app  
The only thing that changes is the token generation (the API calls will remain the same)

With the JWT app type you use your API key and Secret to create a JWT token.  
With the Server to Server OAuth endpoint, you will use the credentials associated with your app (account ID, client ID and client Secret) to request an access\_token to our OAuth endpoint

Here’s a helpful post on how to generate access tokens using Postman

Hi @milaapmp  
Thanks for reaching out to us!  
It looks like you are passing the wrong grant\_type when generating your access\_token,.  
Make sure that the grant\_type is **account\_credentials** instead of client\_credentials

Dear Elisa,

Greetings.

We have created a page with all OAuth feature [http://mpmilaap.in.net/zoomtest](http://mpmilaap.in.net/zoomtest)  
This is a test link where we are click on the create button it will move to Zoom page, after login it will back with token and create the meeting successfully, but it will accept our registered zoom id only, other will not work

Can you help me that once we click on the create button on the given URL , it will create the meeting link without Zoom Login,

Thanks

Tarun Bamba

Hi @milaapmp  
Thanks for reaching out to us.  
If you want users outside of your account to use your app, you will need to publish your app in the Zoom Marketplace

You can publish your app and have it private in the Marketplace team  
And only share the app with the users that you want to use your app
