Connection Token Creation — .NET

In order to authenticate a user connecting to an OpenTok session, a client must connect using a token (see this overview).

The following .NET code shows how to generate a token using the OpenTok .NET SDK:

// Set the following constants with the API key and API secret
// that you receive when you sign up to use the OpenTok API:
OpenTok opentok = new OpenTok(API_KEY, API_SECRET);

//Generate a basic session. Or you could use an existing session ID.
string sessionId = opentok.CreateSession().Id

string token = opentok.GenerateToken(sessionId);

Calling the GenerateToken() method returns a string. This string is the token.

The following .NET code shows how to obtain a token that has a role of "publisher" and that has a connection metadata string:

// Set the following constants with the API key and API secret
// that you receive when you sign up to use the OpenTok API:
OpenTok opentok = new OpenTok(API_KEY, API_SECRET);

//Generate a basic session. Or you could use an existing session ID.
string sessionId = opentok.CreateSession().Id

// Replace with meaningful metadata for the connection.
string connectionMetadata = "username=Bob,userLevel=4";

// Generate a token. Use the Role value appropriate for the user.
string token = opentok.GenerateToken(sessionId, Role.PUBLISHER, Null, connectionMetadata);

The method takes the following arguments:
