Hi [aparab](https://devforum.zoom.us/u/aparab),

Thanks for using Zoom SDK. To host a meeting using StartParam4WithoutLogin, here are the steps:

1. Authenticate with Zoom Rest API, and schedule a meeting([https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingcreate](https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingcreate))
2. Retrieve Zoom token and Zoom Access Token(ZAK) from [https://marketplace.zoom.us/docs/api-reference/zoom-api/users/usertoken](https://marketplace.zoom.us/docs/api-reference/zoom-api/users/usertoken)
3. Pass the userID(email address), meeting number, display name, Zoom token and ZAK to StartParam4WithoutLogin method to host a meeting

You may refer to the implementation in the Windows SDK demo app(The C# wrapper is calling the same Windows SDK interface):[https://github.com/zoom/zoom-sdk-windows/tree/master/demo/sdk\_demo\_v2](https://github.com/zoom/zoom-sdk-windows/tree/master/demo/sdk_demo_v2)

Hope this helps. Thanks!

Hello sir,

Can you send me one example for StartParam4WithoutLogin method.  
I need to know the process with parameters.

When i am trying to start the meeting it goes to join meeting link.

here is my start meeting code.

StartParam4APIUser apiUser = new StartParam4APIUser();  
apiUser.meetingNumber = meetingNumber ;  
apiUser.userID =userID ";  
apiUser.userName =userName ;  
apiUser.userToken = “MjUyLTg1REEyUzMtQLUVJNUI0QTIyMTM2Nzc012M”;

```
        StartParam startParam = new StartParam();
        startParam.apiuserStart = apiUser;
        startParam.userType = SDKUserType.SDK_UT_APIUSER;
        SDKError err = ZOOM_SDK_DOTNET_WRAP.CZoomSDKeDotNetWrap.Instance.GetMeetingServiceWrap().Start(startParam);
```

Thanks for the reply. You may refer to the implementation of the Windows SDK demo app, here are the links to the actually implementation for this scenario:

- [zoomHmacSHA256.cpp](https://github.com/zoom/zoom-sdk-windows/blob/6295059767afa50e42ca8a59ce797a3001684c87/demo/sdk_demo_v2/zoomHmacSHA256.cpp)

- [login\_sdk\_login\_UI.cpp](https://github.com/zoom/zoom-sdk-windows/blob/6295059767afa50e42ca8a59ce797a3001684c87/demo/sdk_demo_v2/LOGIN_sdk_login_UI.cpp)
- [login\_restapi\_without\_login\_workflow.cpp](https://github.com/zoom/zoom-sdk-windows/blob/6295059767afa50e42ca8a59ce797a3001684c87/demo/sdk_demo_v2/LOGIN_restapi_without_login_workflow.cpp)
