Meeting apps APIs

The meeting extensibility provides APIs to enhance meeting experience. You can perform the following with help of the listed APIs:

  • Build apps or integrate existing apps within meeting lifecycle.
  • Use APIs to make your app aware of meeting.
  • Select required APIs to improve the meeting experience.

Poznámka

Use the Microsoft Teams JavaScript client library (TeamsJS) (Version: 1.10 and later) for single sign-on (SSO) to work in meeting side panel.

The following table provides a list of APIs available across the Microsoft Teams JavaScript library and Microsoft Bot Framework SDKs:

Method Description Source
Get user context Get contextual information to display relevant content in a Microsoft Teams tab. TeamsJS library
Get participant Fetch participant information by meeting ID and participant ID. Microsoft Bot Framework SDK
Send in-meeting notification Provides meeting signals using the existing conversation notification API for user-bot chat and allows the bot to notify user action that shows an in-meeting notification. Microsoft Bot Framework SDK
Get meeting details Get a meeting's static metadata. Microsoft Bot Framework SDK
Send real-time captions Send real-time captions to an ongoing meeting. TeamsJS library
Share app content to stage Share specific parts of the app to meeting stage from the app side panel in a meeting. TeamsJS library
Receive real-time Teams meeting events Receive real-time meeting events, such as meeting start and end or participant join and leave. Microsoft Bot Framework SDK
Get incoming audio state Allows an app to get the incoming audio state setting for the meeting user. TeamsJS library
Toggle incoming audio Allows an app to toggle the incoming audio state setting for the meeting user from mute to unmute or vice-versa. TeamsJS library

Get user context API

Dôležité

  • By default, the new Teams client supports light theme for apps in Teams meetings. When the app.theme property in getContext API returns the default value, Teams client is in light theme.
  • Earlier version of Teams clients only support Dark and Contrast theme for apps in Teams meetings

To identify and retrieve contextual information for your tab content, see get context for your Teams tab. meetingId is used by a tab running in the meeting context and is added for the response payload.

Examples

The following are the TeamsJS v2 responses for Get user context API based on meeting type, user type, and call type:

Get participant API

The GetParticipant API must have a bot registration and ID to generate auth tokens. For more information, see bot registration and ID.

Poznámka

  • The user type isn't included in the getParticipantRole API.
  • Do not cache participant roles since the meeting organizer can change the roles any time.
  • The GetParticipant API is only supported for distributions lists or rosters with less than 350 participants.

Query parameters

Tip

Get participant IDs and tenant IDs from the tab SSO authentication.

The Meeting API must have meetingId, participantId, and tenantId as URL parameters. The parameters are available as part of the Microsoft Teams JavaScript client library (TeamsJS) library and bot activity.

The following table includes the query parameters:

Value Type Required Description
meetingId String Yes The meeting identifier is available through Bot Invoke and TeamsJS library.
participantId String Yes The participant ID is the user ID. It's available in Tab SSO, Bot Invoke, and TeamsJS library. It's recommended to get a participant ID from the Tab SSO.
tenantId String Yes The tenant ID is required for the tenant users. It's available in Tab SSO, Bot Invoke, and TeamsJS library. It's recommended to get a tenant ID from the Tab SSO.

Example

protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
{
  // Gets the details for the given meeting participant. 
  // This only works in Teams meeting scoped conversations.
  TeamsMeetingParticipant participant = await TeamsInfo.GetMeetingParticipantAsync(turnContext, "yourMeetingId", "yourParticipantId", "yourParticipantTenantId").ConfigureAwait(false);
  TeamsChannelAccount member = participant.User;
  MeetingParticipantInfo meetingInfo = participant.Meeting;
  ConversationAccount conversation = participant.Conversation;

  // Sends a message activity to the sender of the incoming activity. 
  await turnContext.SendActivityAsync(MessageFactory.Text($"The participant role is: {meetingInfo.Role}"), cancellationToken);
}
Property name Description
user.id ID of the user.
user.aadObjectId Microsoft Entra object ID of the user.
user.name Name of the user.
user.givenName First Name of the user.
user.surname Last Name of the user.
user.email Mail ID of the user.
user.userPrincipalName UPN of the user.
user.tenantId Microsoft Entra tenant ID.
user.userRole Role of the user. For example, 'admin' or 'user'.
meeting.role The participant's role in the meeting. For example, 'Organizer' or 'Presenter' or 'Attendee'.
meeting.inMeeting The value indicating if the participant is in the meeting.
conversation.id The meeting chat ID.
conversation.isGroup Boolean indicating whether conversation has more than two participants.

Response codes

The following table provides the response codes:

Response code Description
403 Get participant information isn't shared with the app. If the app isn't installed in the meeting, it triggers the error response 403. If the tenant admin disables or blocks the app during live site migration, it triggers the error response 403.
200 The participant information is successfully retrieved.
401 The app responds with an invalid token.
404 The meeting has either expired or participants aren't available.

Send an in-meeting notification

All users in a meeting receive the notifications sent through in-meeting notification payload. In-meeting notification payload triggers an in-meeting notification and enables you to provide meeting signals that are delivered using the existing conversation notification API for user-bot chat. You can send an in-meeting notification based on user action. The payload is available through Bot Services.

You can also send targeted in-meeting notification to a specific participant in a meeting. For more information, see Targeted in-meeting notification.

Poznámka

  • When an in-meeting notification is invoked, the content is presented as a chat message.
  • You must invoke the submitTask() function to dismiss automatically after a user takes an action in the web view. This is a requirement for app submission. For more information, see Teams SDK task module.
  • If you want your app to support anonymous users, initial invoke request payload must rely on from.id request metadata in from object, not from.aadObjectId request metadata. from.id is the user ID and from.aadObjectId is the Microsoft Entra ID of the user. For more information, see using task modules in tabs and create and send the task module.

Query parameter

The following table includes the query parameter:

Value Type Required Description
conversationId String Yes The conversation identifier is available as part of Bot Invoke.

Examples

Bot ID is declared in the manifest and the bot receives a result object.

Poznámka

  • The completionBotId parameter of the externalResourceUrl is optional in the requested payload example.
  • The externalResourceUrl width and height parameters must be in pixels. For more information, see design guidelines.
  • The URL is the page, which loads as <iframe> in the in-meeting notification. The domain must be in the apps' validDomains array in your app manifest.
// Specifies the type of text data in a message attachment.
Activity activity = MessageFactory.Text("This is a meeting signal test");

// Configures the current activity to generate a notification within Teams.
activity.TeamsNotifyUser(true, "https://teams.microsoft.com/l/bubble/APP_ID?url=<url>&height=<height>&width=<width>&title=<title>&completionBotId=BOT_APP_ID");

// Sends a message activity to the sender of the incoming activity. 
await turnContext.SendActivityAsync(activity).ConfigureAwait(false);
Property name Description
type Type of activity.
text The text content of the message.
summary The summary text of the message.
channelData.notification.alertInMeeting Boolean indicating if a notification is to be shown to the user while in a meeting.
channelData.notification.externalResourceUrl The value of the notification's external resource URL.
replyToId The ID of the parent or root message of the thread.
APP_ID App ID declared in manifest.
completionBotId Bot app ID.

Response codes

The following table includes the response codes:

Response code Description
201 The activity with signal is successfully sent.
401 The app responds with an invalid token.
403 The app is unable to send the signal. 403 response code can occur because of various reasons, such as the tenant admin disables and blocks the app during live site migration. In this case, the payload contains a detailed error message.
404 The meeting chat doesn't exist.

Targeted meeting notification and app icon badging API

The targetedMeetingNotification API allows apps to send targeted in-meeting notifications and shows app icon badging to specific participants in a meeting. Apps send targeted in-meeting notifications and app icon badging based on user action. The API is available through bot API.

Prerequisite

You must configure your app manifest with RSC permissions under the webApplicationInfo property to send targeted in-meeting notifications and shows app icon badging to specific participants in a meeting. Use the following examples to configure your manifest:


For app manifest version 1.12 and later
"webApplicationInfo": {
    "id": "<<MICROSOFT-APP-ID>>",
    "resource": "https://RscBasedStoreApp"  },
  "authorization": {
    "permissions": {
      "resourceSpecific": [
            {
                "name": "OnlineMeetingNotification.Send.Chat",
                "type": "Application"
            }
        ]    
    }
}


For app manifest version 1.11 and earlier
"webApplicationInfo": {
    "id": "<<MICROSOFT-APP-ID>>",
    "resource": "https://RscBasedStoreApp",
    "applicationPermissions": [
      "OnlineMeetingNotification.Send.Chat"
    ]
}

Poznámka

  • The API payload only permits a dialog with a URL.
  • The user ID formats aadObjectid and UPN aren't supported.

Get supported user ID format for targeted in-meeting notification and app icon badging:

Get meeting details API

The meeting details API enables your app to get a meeting's static metadata. The metadata provides data points that don't change dynamically. The API is available through Bot Services. Both private scheduled or recurring meetings and channel scheduled or recurring meetings support API with different RSC permissions respectively.

The meeting details API must have a bot registration and bot ID. It requires Bot SDK to get TurnContext. To use the meeting details API, you must obtain different RSC permission based on the scope of any meeting, such as private meeting or channel meeting.

Poznámka

The meeting details API is supported for scheduled private meetings, scheduled channel meeting, instant meetings (Meet now), one-on-one calls, and group calls in Teams desktop and mobile clients.

Prerequisite

To use the meeting details API, you must obtain different RSC permission based on the scope of any meeting, such as private meeting or channel meeting.


For app manifest version 1.12 and later

Use the following example to configure your app manifest's webApplicationInfo and authorization properties for any private meeting:

"webApplicationInfo": {
    "id": "<bot id>",
    "resource": "https://RscPermission",
},
"authorization": {
    "permissions": {
        "resourceSpecific": [
            {
                "name": "OnlineMeeting.ReadBasic.Chat",
                "type": "Application"
            }
        ]
    }
}

Use the following example to configure your app manifest's webApplicationInfo and authorization properties for any channel meeting:

"webApplicationInfo": {
    "id": "<bot id>",
    "resource": "https://RscPermission",
},
"authorization": {
    "permissions": {
        "resourceSpecific": [
            {
                "name": "ChannelMeeting.ReadBasic.Group",
                "type": "Application"
            }
        ]
    }
}


For app manifest version 1.11 and earlier

Use the following example to configure your app manifest's webApplicationInfo property for any private meeting:

"webApplicationInfo": {
    "id": "<bot id>",
    "resource": "https://RscPermission",
    "applicationPermissions": [
      "OnlineMeeting.ReadBasic.Chat"
    ]
}

Use the following example to configure your app manifest's webApplicationInfo property for any channel meeting:

"webApplicationInfo": {
    "id": "<bot id>",
    "resource": "https://RscPermission",
    "applicationPermissions": [
      "ChannelMeeting.ReadBasic.Group"
    ]
}

Poznámka

  • If the ChannelMeeting.ReadBasic.Group permission is added to the manifest, the bot receives the meeting start or end events automatically from the channel meetings created in all the teams where the bot is added.
  • For a one-on-one call organizer is the initiator of the chat and for group calls organizer is the call initiator. For public channel meetings organizer is the person who created the channel post.

Query parameter

The following table lists the query parameter:

Value Type Required Description
meetingId String Yes The meeting identifier is available through Bot Invoke and the TeamsJS library.

Example

// Gets the information for the given meeting id.

endDate: Specifies the date to stop applying the pattern. The last occurrence of the meeting might not occur on this date if it doesn't fit the pattern.

Send real-time captions API

The send real-time captions API exposes a POST endpoint for Teams communication access real-time translation (CART) captions, human-typed closed captions. Text content sent to this endpoint appears to end users in a Teams meeting when they have captions enabled.

CART URL

You can get the CART URL for the POST endpoint from the Meeting options page in a Teams meeting. For more information, see CART captions in a Microsoft Teams meeting. You don't need to modify the CART URL to use CART captions.

Query Parameter

The CART URL includes the following query parameters:

Value Type Required Description
meetingId String Yes The meeting identifier is available through Bot Invoke and the TeamsJS library.
For example, meetingid=%7b%22tId%22%3a%2272f234bf-86f1-41af-91ab-2d7cd0321b47%22%2c%22oId%22%3a%22e071f268-4241-47f8-8cf3-fc6b84437f23%22%2c%22thId%22%3a%2219%3ameeting_NzJiMjNkMGQtYzk3NS00ZDI1LWJjN2QtMDgyODVhZmI3NzJj%40thread.v2%22%2c%22mId%22%3a%220%22%7d

Receive real-time Teams meeting events

You can receive real-time meeting events such as meeting start and end or participant join and leave events.

Receive meeting start and end events

Poznámka

Meeting start and end events are supported for scheduled and channel meetings.

The user can receive real-time meeting events. As soon as any app is associated with a meeting, the actual meeting start and end time are shared with the bot. The actual start and end time of a meeting are different from scheduled start and end time. The meeting details API provides the scheduled start and end time. The event provides the actual start and end time.

If the ChannelMeeting.ReadBasic.Group and OnlineMeeting.ReadBasic.Chat permissions are added in the manifest, the bot automatically starts receiving the meeting start or end events for the scheduled and channel meeting types.

Prerequisite

Your app manifest must have the webApplicationInfo property to receive the meeting start and end events. Use the following examples to configure your manifest:


For app manifest version 1.12 and later
"webApplicationInfo": {
    "id": "<bot id>",
    "resource": "https://RscPermission",
    },
"authorization": {
    "permissions": {
        "resourceSpecific": [
            {
                "name": "OnlineMeeting.ReadBasic.Chat",
                "type": "Application"
            }
            {
                "name": "ChannelMeeting.ReadBasic.Group",
                "type": "Application"
            }
        ]    
    }
}


For app manifest version 1.11 and earlier
"webApplicationInfo": {
    "id": "<bot id>",
    "resource": "https://RscPermission",
    "applicationPermissions": [
      "OnlineMeeting.ReadBasic.Chat",
      "ChannelMeeting.ReadBasic.Group"
    ]
}

Example of getting meeting start or end events

The bot receives the meeting start and meeting end events through the OnTeamsMeetingStartAsync and OnTeamsMeetingEndAsync handlers. The information related to the meeting event is part of the MeetingStartEventDetails object, which includes the metadata fields such as, meetingType, title, id, joinUrl, startTime, and EndTime.

Poznámka

  • Get meeting ID from turnContext.ChannelData.
  • Do not use conversation ID as meeting ID.
  • Do not use meeting ID from meeting events payload turncontext.activity.value.

The following examples show how to capture the meeting start and end events:

Meeting Start Event

// Invoked when a Teams Meeting Start event activity is received from the connector.
protected override async Task OnTeamsMeetingStartAsync(MeetingStartEventDetails meeting, ITurnContext<IEventActivity> turnContext, CancellationToken cancellationToken)
{
    // Sends a message activity to the sender of the incoming activity. 
    await turnContext.SendActivityAsync(JsonConvert.SerializeObject(meeting));
}

Meeting End Event

// Invoked when a Teams Meeting End event activity is received from the connector.
protected override async Task OnTeamsMeetingEndAsync(MeetingEndEventDetails meeting, ITurnContext<IEventActivity> turnContext, CancellationToken cancellationToken)
{
    // Sends a message activity to the sender of the incoming activity.
    await turnContext.SendActivityAsync(JsonConvert.SerializeObject(meeting));
}

Receive meeting participant events

Your bot can receive real-time meeting events such as participant join and leave events. A bot can receive the participant events only if subscribed to these events in Developer Portal.

Poznámka

  • Participant events are supported only for scheduled meetings.
  • For a bot to receive participant events, ensure that you add the bot to the meeting before a participant joins or leaves the meeting.

To subscribe to participant events, follow these steps:

  1. In Developer Portal open your bot app or import an existing app.

  2. In the Meeting event subscriptions section, select the events:

    • Participant join
    • Participant leave
  3. Select Save

    Screenshot shows how developer portal display for participant events.

  4. Ensure that the OnlineMeetingParticipant.Read.Chat RSC permission is configured in your app manifest.

    If your app doesn't have the RSC permission, add it through the Configure > Permissions section of your app in Developer Portal. For more information, see RSC permissions.

The following examples show how to capture the participant join and leave events:

//Invoked on participant join a meeting
protected override async Task OnTeamsMeetingParticipantsJoinAsync(MeetingParticipantsEventDetails meeting, ITurnContext<IEventActivity> turnContext, CancellationToken cancellationToken)
{
  await turnContext.SendActivityAsync("Member has joined the meeting.");
  return;
}

Following are the examples of the participant join and leave event payloads:

The following is an example of the participant join event payload:
