How to get identity Teams user for joining a Teams meeting

Question

Hello!

I use CallWithChatComposite to join a Teams meeting. One of the required props is "adapter" that require "userId" with a "CommunicationUserIdentifier" value:

export declare type AzureCommunicationCallWithChatAdapterArgs = {
    endpoint: string;
    userId: CommunicationUserIdentifier;
    displayName: string;
    credential: CommunicationTokenCredential;
    locator: CallAndChatLocator | TeamsMeetingLinkLocator;
    callAdapterOptions?: AzureCommunicationCallAdapterOptions;
};

export declare interface CommunicationUserIdentifier {
    /**
     * Id of the CommunicationUser as returned from the Communication Service.
     */
    communicationUserId: string;
}

For an external identity, I know to create a user access token and a userId as described here, but regarding a Teams identity I know to generate a user access token as described here, but which userId should I use? I try to use:

export const getUserId = async function () {
  const account = msalInstance.getActiveAccount();
  return account.localAccountId;
}

But it doesn't work.

I will appreciate you help

Issue: You were unable to obtain the Team's user identity.

Solution: You were able to use the below code to obtain the necessary Team's user identity.

const communicationUserId = getIdentifierRawId({ "<TEAMS_USER_OBJECT_ID>" });

@Yossi Cahen To get the identity of a Teams user for joining a Teams meeting, you can use the getTokenForTeamsUser method of the CommunicationIdentityClient class to get a Communication Services access token for the Teams user.

Here's an example of how to get the communicationUserId for a Teams user:

const identityClient = new CommunicationIdentityClient("<COMMUNICATION_SERVICES_CONNECTION_STRING>");
const teamsUserAadToken = "<TEAMS_USER_AAD_TOKEN>";
const clientId = "<AAD_CLIENT_ID>";
const userObjectId = "<TEAMS_USER_OBJECT_ID>";

const accessToken = await identityClient.getTokenForTeamsUser({
    teamsUserAadToken: teamsUserAadToken,
    clientId: clientId,
    userObjectId: userObjectId,
});

const communicationUserId = { communicationUserId: accessToken.user.communicationUserId };

You can then use the communicationUserId object as the userId parameter when creating the AzureCommunicationCallWithChatAdapterArgs object for the CallWithChatComposite component.

It doesn't work.

That works for me:

const communicationUserId = getIdentifierRawId({ "<TEAMS_USER_OBJECT_ID>" });
