MS Teams Task

The msteams plugin supports interaction with the Microsoft Teams messaging platform.

• Usage
• Version 2 (Recommended)
• Version 1

Usage

To be able to use the MSTeams task in a Concord flow, it must be added as a dependency:

configuration:
  dependencies:
  - mvn://com.walmartlabs.concord.plugins:msteams-task:2.9.0

This adds the task to the classpath and allows you to invoke the MSTeams task.

Version 2

• Why V2
• Prerequisite
• Common Parameters

Possible operations are:

• Create Conversation
• Reply To Conversation

Why V2

We recommend users to use or move to msteamsV2 for following reasons:

1. Unlike V1, adding concord-bot to a team, makes it available for all public channels in a team.
2. Supports replyToConversation action.
3. Future enhancements (if any), will be made on V2.

Prerequisite

Add concord-bot to your MS Team/channel. Follow below steps to add it from MS Teams UI.

1. Click on ellipsis (3 dots) next to the Team you want to add the Bot to, then click on Manage Team.
2. Click on Apps tab and then click on More Apps button.
3. In the new window opened, search for concord-bot.
4. Click on open dropdown and select Add to a team.
5. Type the team or channel name and click Set up a bot.

Private channels do not support bots. Make sure your channel is not marked as private. For more details check here.

Common Parameters

The MSTeams task uses a number of input parameters that are common for all operations:

• task - determines name of task. Should be msteamsV2 if you are using version 2;
• action - determines the operation to be performed with the current invocation of the MSTeams task.
• ignoreErrors - boolean value, if true any errors that occur during the execution are ignored and stored in the result variable. Defaults to false.

The tenantId, useProxy, proxyAddress, proxyPort,clientId, clientSecret, rootApi, and accessTokenApi variables configure the connection to the MS Teams server. They are best configured globally as [default process configuration] (../getting-started/configuration.html#default-process-variable) with an msteamsParams argument.

configuration:
  arguments:
    msteamsParams:
      tenantId: "myTenantID"
      useProxy: true
      proxyAddress: "proxy.example.com"
      proxyPort: 8080
      clientId: "botId"
      clientSecret: "botSecret"
      rootApi: "https://smba.trafficmanager.net/amer/v3/conversations"
      accessTokenApi: "https://login.microsoftonline.com/botframework.com/oauth2/v2.0/token"

• useProxy - boolean value, if true uses the proxyAddress and proxyPort set in default vars. Defaults to false.
• clientId - determines the id associated with bot.
• clientSecret - determines the secret associated with bot.

Note: your Concord environment may provide other defaults using the default variables.

Create Conversation

The createConversation action allows users to create a new conversation in a specific MSTeams channel. It uses input parameters listed below for the operation.

• channelId: string, required - the Id of the MS teams channel. It can be seen in the URL opened by clicking 3 dots -> Get link to channel link next to your channel.
• activity: map, required - initial message to send to the conversation when it is created. More details about activity object can be found here, but a simple example can look like as shown below.

flows:
  default:
  - task: msteamsV2
    in:
      action: createConversation
      activity:
        type: message
        text: "My First Message"
      channelId: "myChannelId"
      ignoreErrors: true

  - log: "Result status: ${result.ok}"
  - if: "${!result.ok}"
    then:
    - throw: "Error occurred while sending a message: ${result.error}"

  ...

The task returns a result object with following fields:

• ok - true if the operation is succeeded.
• data - string - response body, if the operation is succeeded.
• error - error message if the operation failed.
• coversationId - ID of the conversation that was posted, can be used, in the following msteams task to reply to a conversation.
• activityId - ID of the activity, if sent.

Reply To Conversation

The replyToConversation action allows users to reply to an existing conversation in a specific MSTeams channel. It uses input parameters listed below for the operation.

• coversationId: string, required - the Id of the conversation that was previously posted.
• activity: map, required - message used to reply to a conversation.

- task: msteamsV2
    in:
      action: replyToConversation
      conversationId: ${result.conversationId}
      activity:
        type: message
        text: "This replies to a previously posted conversation"
