**Description**  
I am not able to start the meeting as an API user. I am using the C# wrapper in my WPF app. I want to start the meeting after adding the current user as an alternate host in the meeting through the meeting update API. I also check the meeting alternate hosts and it update the meeting successfully with the my alternate host added to the meeting.

I start the meeting using following code. Instead of starting the meeting as a host it shows the waiting for host dialog.

ZOOM\_SDK\_DOTNET\_WRAP.StartParam4APIUser start\_api\_param = new ZOOM\_SDK\_DOTNET\_WRAP.StartParam4APIUser();  
start\_api\_param.meetingNumber = meetingNumber;  
start\_api\_param.isDirectShareDesktop = true;  
start\_api\_param.hDirectShareAppWnd = shareWindow;  
start\_api\_param.userToken = token;  
start\_api\_param.userID = userID;  
start\_api\_param.userName = displayName;

param.apiuserStart = start\_api\_param;  
ZOOM\_SDK\_DOTNET\_WRAP.SDKError err = ZOOM\_SDK\_DOTNET\_WRAP.CZoomSDKeDotNetWrap.Instance.GetMeetingServiceWrap().Start(param);

**Please note that it was all working fine and meeting was starting as host correctly in the old SDK, before I used the latest SDK.**

Please advice, how can I fix it. I need to fix it in a few hours. It is very urgent for me, please help.

**Which version?**  
Latest version

Hi @Bert_Leatherman,

Thanks for the post. Are you passing `userZAK` in the parameter? Without that, you will not be able to host a meeting with tokens. You may refer to the implementation in our demo:[https://github.com/zoom/zoom-c-sharp-wrapper/blob/5500fbaac55b10068f1f05b166755048a8ca2034/zoom\_sdk\_demo/start\_join\_meeting.xaml.cs#L101](https://github.com/zoom/zoom-c-sharp-wrapper/blob/5500fbaac55b10068f1f05b166755048a8ca2034/zoom_sdk_demo/start_join_meeting.xaml.cs#L101)
