Deep link to Teams chat

  • Makale

You can create a deep link to a Teams chat, such as to start a new chat, go to a channel conversation, and access a file within a channel.

In this article, you’ll learn to create:

You can navigate to or create private chats between users with the Microsoft Teams JavaScript client library (TeamsJS) by specifying the set of participants. If a chat doesn’t exist with the specified participants, the user is navigated to an empty new chat.

When a user creates a new chat using a deep link, Teams creates the new chat in the draft state until the user sends the first message. You can also provide the name of the chat if it doesn’t already exist, along with text that should be inserted into the user's compose box. Consider this a shortcut for the user taking the manual action of navigating to or creating the chat and then compose the message.

As a use-case example, if you’re retrieving a Microsoft 365 user profile information from your bot as a card, this deep link can allow the app user to easily chat with that person.

You can configure deep links to start a new chat in one of the following two ways:

While use of the typed APIs is recommended, you can alternatively use the following format for a manually created deep link that you can use in a bot, connector, or message extension card:

https://teams.microsoft.com/l/chat/0/0?tenantId=<tenantId>&users=<user1>,<user2>,...&topicName=<chat name>&message=<precanned text>

To use this deep link with your bot, specify the deep link as the URL target in your card's button or tap action through the openUrl action type.

The query parameters are:

  • users: A comma-separated list of user IDs representing the participants of the chat. The user that performs the action is always included as a participant. The User ID parameter supports the Microsoft Entra UserPrincipalName, such as an email address only.
  • topicName: An optional parameter for chat's display name if a chat has three or more users. If this field isn't specified, the chat's display name is based on the names of the participants.
  • message: An optional field for the message text that you want to insert into the current app user's compose box while the chat is in the draft state.

Example: https://teams.microsoft.com/l/chat/0/0?users=joe@contoso.com,bob@contoso.com&topicName=Prep%20For%20Meeting%20Tomorrow&message=Hi%20folks%2C%20kicking%20off%20a%20chat%20about%20our%20meeting%20tomorrow

The following example demonstrates how to open a chat message to a group of participants with an initial message. You can target the deep link to an existing or a new chat. If a chat already exists, the deep link opens in that chat.

if(chat.isSupported()) {
    const chatPromise = chat.openGroupChat({ users: ["joe@contoso.com","bob@contoso.com"], topic: "Prep For Meeting Tomorrow", message: "Hi folks kicking off chat about our meeting tomorrow"});
    chatPromise.
      then((result) => {/*Successful operation*/}).
      catch((error) => {/*Unsuccessful operation*/});
}
else { /* handle case where capability isn't supported */ }

To navigate to a specific chat conversation in Teams, use the following deep link format:

https://teams.microsoft.com/l/chat/<chatId>/conversations

The query parameter is chatId, which represents chat ID of the conversation. The supported format for chatId is 19:xxx.

Example: https://teams.microsoft.com/l/chat/19:c6d70e392a384916c3262b15406d763e@thread.v2/conversations

You can use the following deep link format to go to a particular conversation within channel thread:

https://teams.microsoft.com/l/message/<channelId>/<parentMessageId>?tenantId=<tenantId>&groupId=<groupId>&parentMessageId=<parentMessageId>&teamName=<teamName>&channelName=<channelName>&createdTime=<createdTime>

The query parameters are:

  • channelId: Channel ID of the conversation. For example, 19:3997a8734ee5432bb9cdedb7c432ae7d@thread.tacv2.
  • tenantId: Tenant ID, such as 0d9b645f-597b-41f0-a2a3-ef103fbd91bb.
  • groupId: Group ID of the file. For example, 3606f714-ec2e-41b3-9ad1-6afb331bd35d.
  • parentMessageId: Parent message ID of the conversation.
  • teamName: Name of the team.
  • channelName: Name of the team's channel.

Note

You can see channelId and groupId in the URL from the channel.

Example: https://teams.microsoft.com/l/message/<channelId>/1648741500652?tenantId=<tenantId>&groupId=<groupId>&parentMessageId=1648741500652&teamName=<teamName>&channelName=<channelName>&createdTime=1648741500652

Use the following deep link format to navigate a user to a message in a personal or group chat in Teams:

https://teams.microsoft.com/l/message/{chatId}/{messageId}?tenantId=<tenantId>?context={"contextType":"chat"}

The query parameters are:

  • chatId: Chat ID of the conversation. The supported format for chatId is 19: xxx. For example, 19:253f5895-9a62-4362-8d38-43f0205c702c_f1b94dcf-0aa3-4989-bcdf-ef4a5ed00f86@unq.gbl.spaces.
    Apps can read a chat ID through app context in Teams, incoming payload to bot, or through Microsoft Graph APIs.

    Note

    For one-on-one chats with bot, the incoming payload to bot contains the conversation ID in a:xxx format.

  • messageId: Unique message ID of each message in a chat. When a bot posts a message in chat, the messageId is returned. You can also get the messageId through Microsoft Graph APIs. For example, 1563480968434.
  • context: Specify the contextType as chat.

Example: https://teams.microsoft.com/l/message/19:253f5895-9a62-4362-8d38-43f0205c702c_f1b94dcf-0aa3-4989-bcdf-ef4a5ed00f86@unq.gbl.spaces/1563480968434?context=%7B%22contextType%22:%22chat%22%7D

You can start a conversation with a bot using a prepopulated message through a deep link. Use the bot ID prefixed with 28: in place of an email address. The format of the deep link is:

https://teams.microsoft.com/l/chat/0/0?users=28:[bot guid]&message=This%20message%20was%20triggered%20by%20a%20link!

The query parameter is bot guid, which is the bot ID attribute in the app manifest.

Example: https://teams.microsoft.com/l/chat/0/0?users=28:47345678-2134-6534-9143-65146789012&message=This%20message%20was%20triggered%20by%20a%20link!

The deep link provided only loads the message into the chat text box of the bot, and doesn't send the message automatically. To send the message, you must either select the Send button or select Enter.

To navigate to a particular team, use the following deep link format:

https://teams.microsoft.com/l/team/<channelId>/conversations?groupId=<groupId>&tenantId=<tenantId>

The query parameters are:

  • channelId: Channel ID of the conversation (URL encoded). For example, 19%3ATWLPKo8lD4v8zDxyw4FnDYY-ovnBJG5CSjmrHUAoOz41%40thread.tacv2.
  • groupId: Group ID of the file. For example, 72602e12-78ac-474c-99d6-f619710353a9.
  • tenantId: Tenant ID, such as 72f988bf-86f1-41af-91ab-2d7cd011db47.

Note

You can get channelId and groupId in the URL from the team.

Example: https://teams.microsoft.com/l/team/19%3ATWLPKo8lD4v8zDxyw4FnDYY-ovnBJG5CSjmrHUAoOz41%40thread.tacv2/conversations?groupId=72602e12-78ac-474c-99d6-f619710353a9&tenantId=72f988bf-86f1-41af-91ab-2d7cd011db47

You can use the following deep link formats to navigate to particular channels:

  • Standard channel: https://teams.microsoft.com/l/channel/<channelId>/<channelName>?groupId=<groupId>&tenantId=<tenantId>

    Example: https://teams.microsoft.com/l/channel/19%3A9be3de4e70874c71a608dee9ba803ed3%40thread.tacv2/My%20example%20channel?groupId=72602e12-78ac-474c-99d6-f619710353a9&tenantId=72f988bf-86f1-41af-91ab-2d7cd011db47

Note

  • You can see threadId and groupId in the URL from the channel.
  • In the new Teams client, the deep link format using objectURL for a file in a channel isn't supported, use objectUrl in the deep link format.

The following example format illustrates the deep link to files:

https://teams.microsoft.com/l/file/5E0154FC-F2B4-4DA5-8CDA-F096E72C0A80?tenantId=0d9b645f-597b-41f0-a2a3-ef103fbd91bb&fileType=pptx&objectUrl=https%3A%2F%2Fmicrosoft.sharepoint.com%2Fteams%2FActionPlatform%2FShared%20Documents%2FFC7-%20Bot%20and%20Action%20Infra%2FKaizala%20Actions%20in%20Adaptive%20Cards%20-%20Deck.pptx&baseUrl=https%3A%2F%2Fmicrosoft.sharepoint.com%2Fteams%2FActionPlatform&serviceName=teams&threadId=19:f8fbfc4d89e24ef5b3b8692538cebeb7@thread.skype&groupId=ae063b79-5315-4ddb-ba70-27328ba6c31e
