Azure Communication Identity client library for .NET

Azure Communication Identity is managing tokens for Azure Communication Services.

Source code | Product documentation | Samples

Getting started

Install the package

Install the Azure Communication Identity client library for .NET with NuGet:

dotnet add package Azure.Communication.Identity

Prerequisites

You need an Azure subscription and a Communication Service Resource to use this package.

To create a new Communication Service, you can use the Azure Portal, the Azure PowerShell, or the .NET management client library.

Authenticate the client

The identity client can be authenticated using a connection string acquired from an Azure Communication Resources in the Azure Portal.

// Get a connection string to our Azure Communication resource.
var connectionString = "<connection_string>";
var client = new CommunicationIdentityClient(connectionString);

Or alternatively using the endpoint and access key acquired from an Azure Communication Resources in the Azure Portal.

var endpoint = new Uri("https://my-resource.communication.azure.com");
var accessKey = "<access_key>";
var client = new CommunicationIdentityClient(endpoint, new AzureKeyCredential(accessKey));

Clients also have the option to authenticate using a valid Active Directory token.

var endpoint = new Uri("https://my-resource.communication.azure.com");
TokenCredential tokenCredential = new DefaultAzureCredential();
var client = new CommunicationIdentityClient(endpoint, tokenCredential);

Key concepts

CommunicationIdentityClient provides the functionalities to manage user access tokens: creating new ones and revoking them.

Thread safety

We guarantee that all client instance methods are thread-safe and independent of each other (guideline). This ensures that the recommendation of reusing client instances is always safe, even across threads.

Additional concepts

Client options | Accessing the response | Long-running operations | Handling failures | Diagnostics | Mocking | Client lifetime

Examples

Creating a new user

Response<CommunicationUserIdentifier> userResponse = await client.CreateUserAsync();
CommunicationUserIdentifier user = userResponse.Value;
Console.WriteLine($"User id: {user.Id}");

Getting a token for an existing user

Response<AccessToken> tokenResponse = await client.GetTokenAsync(user, scopes: new[] { CommunicationTokenScope.Chat });
string token = tokenResponse.Value.Token;
DateTimeOffset expiresOn = tokenResponse.Value.ExpiresOn;
Console.WriteLine($"Token: {token}");
Console.WriteLine($"Expires On: {expiresOn}");

Creating a user and a token in the same request

Response<CommunicationUserIdentifierAndToken> response = await client.CreateUserAndTokenAsync(scopes: new[] { CommunicationTokenScope.Chat });
var (user, token) = response.Value;
Console.WriteLine($"User id: {user.Id}");
Console.WriteLine($"Token: {token.Token}");

Revoking a user's tokens

In case a user's tokens are compromised or need to be revoked:

Response revokeResponse = await client.RevokeTokensAsync(user);

Deleting a user

Response deleteResponse = await client.DeleteUserAsync(user);

Exchanging Azure AD access token of a Teams User for a Communication Identity access token

The CommunicationIdentityClient can be used to exchange an Azure AD access token of a Teams user for a new Communication Identity access token with a matching expiration time.

The GetTokenForTeamsUser function accepts the following parameters wrapped into the GetTokenForTeamsUserOptions option bag:

  • teamsUserAadToken Azure Active Directory access token of a Teams user
  • clientId Client ID of an Azure AD application to be verified against the appId claim in the Azure AD access token
  • userObjectId Object ID of an Azure AD user (Teams User) to be verified against the OID claim in the Azure AD access token
Response<AccessToken> tokenResponse = await client.GetTokenForTeamsUserAsync(new GetTokenForTeamsUserOptions(teamsUserAadToken, clientId, userObjectId));
string token = tokenResponse.Value.Token;
Console.WriteLine($"Token: {token}");

Troubleshooting

All User token service operations will throw a RequestFailedException on failure.

// Get a connection string to our Azure Communication resource.
var connectionString = "<connection_string>";
var client = new CommunicationIdentityClient(connectionString);

try
{
    Response<CommunicationUserIdentifier> response = await client.CreateUserAsync();
}
catch (RequestFailedException ex)
{
    Console.WriteLine(ex.Message);
}
