@anosingh As per documentation, you need to ping server every 30 sec to keep connection alive. Check if you are sending "ping" using timer. Also which API are you talking about ? I recently successfully ran WebSocket 2.0 for C#.

@Jaydip-Garala vshinde480@gmail.com please send through email if possible.

@Bhagawansahay You need to use updated AngelOne DLL with totp addition.

@Jaydip-Garala Hi Please share working code to connect Webocket 2.0 .

@Vikas_shah1008 Can you post working code to connect to Websocket 2.0 & subscribe / unsubscribe feed ?

@admin Why there is no SDK support for c#?

1. Download angelone solution file from sdk.

2. Edit below code . I have added totp part for post request.

3. Build solution & use generated DLL from this.
   

4. Since Generate session method is updated now, we can pass TOTP parameter.

5. To generate TOPT ,

• Install Otp.Net package from Nuget packages.
  

• Once it is installed, use below function to generate TOTP

  Public Shared Function GetTotp() As String
  Dim secretKey = OtpNet.Base32Encoding.ToBytes("JSPCTWENRTFATEQXFE227P7ADI")
  Dim totp = New Totp(secretKey)
  Dim otp = totp.ComputeTotp()
  Return otp
  End Function

• Aboce code is in vb.net. If required convert it to c# using online converters.

• Use above function to generate TOTP.
  e.g.
  Dim totp as string
  totp = GetTotp()

Use above lines of code before calling Generatesession method.

• Finally , it will pass post data to url & you will be able to login successfully.

@Swetha Pass mPin insteed of password. Also please let me know how did you modify Generate session method ?
