Examples

Initializing Relay Client

The following section provides code snippets covering some of the most common Azure Communication Network Traversal tasks, including:

• Getting the relay configuration

# You can find your endpoint and access token from your resource in the Azure Portal
import os
from azure.communication.networktraversal import CommunicationRelayClient
from azure.identity import DefaultAzureCredential
from azure.communication.identity import CommunicationIdentityClient

connection_str = "endpoint=ENDPOINT;accessKey=KEY"
endpoint = "https://<RESOURCE_NAME>.communication.azure.com"

# To use Azure Active Directory Authentication (DefaultAzureCredential) make sure to have
# AZURE_TENANT_ID, AZURE_CLIENT_ID and AZURE_CLIENT_SECRET as env variables.
# We also need Identity client to get a User Identifier
identity_client = CommunicationIdentityClient(endpoint, DefaultAzureCredential())
relay_client = CommunicationRelayClient(endpoint, DefaultAzureCredential())

#You can also authenticate using your connection string

identity_client = CommunicationIdentityClient.from_connection_string(self.connection_string)
relay_client = CommunicationRelayClient.from_connection_string(self.connection_string)

Getting the relay configuration providing a user

# We need a user from Identity
user = identity_client.create_user()
relay_configuration = relay_client.get_relay_configuration(user=user)

for iceServer in config.ice_servers:
    assert iceServer.username is not None
    print('Username: ' + iceServer.username)

    assert iceServer.credential is not None
    print('Credential: ' + iceServer.credential)
    
    assert iceServer.urls is not None
    for url in iceServer.urls:
        print('Url:' + url)

Getting the relay configuration without providing a user

relay_configuration = relay_client.get_relay_configuration()

for iceServer in config.ice_servers:
    assert iceServer.username is not None
    print('Username: ' + iceServer.username)

    assert iceServer.credential is not None
    print('Credential: ' + iceServer.credential)
    
    assert iceServer.urls is not None
    for url in iceServer.urls:
        print('Url:' + url)

Getting the relay configuration without providing a RouteType

# We need a user from Identity
user = identity_client.create_user()
relay_configuration = relay_client.get_relay_configuration(user=user, route_type=RouteType.NEAREST)

for iceServer in config.ice_servers:
    assert iceServer.username is not None
    print('Username: ' + iceServer.username)

    assert iceServer.credential is not None
    print('Credential: ' + iceServer.credential)
    
    assert iceServer.urls is not None
    for url in iceServer.urls:
        print('Url:' + url)

Troubleshooting

The Azure Communication Relay client will raise exceptions defined in Azure Core.
