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 --version 1.0.0
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($"Token: {token.Token}");
Revoking a user's tokens
In case a user's tokens are compromised or need to be revoked:
Response revokeResponse = await client.RevokeTokensAsync(user);
Deleting a user
Response deleteResponse = await client.DeleteUserAsync(user);
Exchanging AAD access token of a Teams User for a Communication Identity access token
Response<AccessToken> tokenResponse = await client.GetTokenForTeamsUserAsync(teamsToken);
string token = tokenResponse.Value.Token;
Console.WriteLine($"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);
}
