I am using the C# windows SDK to Integrate Zoom in my application.

When I start / Join the Call It throws me an SDKERR\_SERVICE\_FAILED error.

Due to which I could not continue to connect Zoom call.

**Notes :**

1. I used Login Type as LoginType\_Email

2. Sample code to Join  
RegisterCallBack();  
ZOOM\_SDK\_DOTNET\_WRAP.JoinParam param = new ZOOM\_SDK\_DOTNET\_WRAP.JoinParam();  
param.userType = ZOOM\_SDK\_DOTNET\_WRAP.SDKUserType.SDK\_UT\_APIUSER;  
ZOOM\_SDK\_DOTNET\_WRAP.JoinParam4APIUser join\_api\_param = new ZOOM\_SDK\_DOTNET\_WRAP.JoinParam4APIUser();  
join\_api\_param.meetingNumber = txtMeetingID.Text;  
join\_api\_param.userName = “Test”;  
param.apiuserJoin = join\_api\_param;
