Microsoft Teams Connector 1.0 Examples - Mule 4

Before You Begin

To run these examples, you must have:

  • A working instance of Microsoft Teams

  • Credentials to access the Microsoft Teams instance

  • Microsoft Teams Connector 1.0 or later

  • Two users in the Microsoft Teams instance: one team owner and one user

  • Anypoint Studio 7.x

Configure OAuth Authorization

Because this connector uses OAuth to secure connections, you must specify OAuth field values, such as client credentials, keys, and OAuth-related URLs. To do this:

  • Create a configuration file for the OAuth connection

  • Configure the OAuth-related global elements

  • Configure a global element for the properties file

Create a Configuration File for the OAuth Connection

Create a configuration file for the OAuth connection that includes properties for the Authorization Code and Client Credentials grant types:

  1. Create a file named mule-app.properties in the /src/main/resources/ folder.

  2. In the mule-app.properties file, create a set of properties for the Authorization Code grant type, similar to the ones that follow, replacing the bracketed text (including the brackets) with the correct values for your OAuth configuration:

    config.oauth.authorization.code.consumerKey=<consumerKey>
config.oauth.authorization.code.consumerSecret=<consumerSecret>
config.oauth.authorization.code.authorizationUrl=<authorizationUrl>
config.oauth.authorization.code.accessTokenUrl=<accessTokenUrl>

  3. In the mule-app.properties file, create a set of properties for the Client Credentials grant type, similar to the one that follows, replacing the bracketed text (including the brackets) with the correct values for your OAuth configuration:

    config.oauth.client.credentials.clientId=<clientId>
config.oauth.client.credentials.clientSecret=<clientSecret>
config.oauth.client.credentials.tokenUrl=<tokenUrl>

For more information about creating a properties file, see Configuring Property Placeholders.

Configure the OAuth Global Elements

Configure global elements for the OAuth_Authorization_Code_Config and OAuth_Client_Credentials_Config files:

  1. Create a new Mule project.

  2. In the Mule Palette view, click Search in Exchange and enter microsoft teams.

  3. Add Microsoft Teams Connector to the Selected modules section and click Finish.

  4. Click the Global Elements tab and click Create.

  2. In the Choose Global Type dialog, select Configuration properties and click OK.

  3. In the File field, enter mule.app.properties.

  4. Click OK.

Create a New Team

The following screenshot shows the Studio app flow for creating a new team:

Create a new team flow
Figure 1. Use a flow like this one to create a new team.

Creating a new team involves configuring an HTTP Listener component, a Transform Message component, a Create Team operation, and a second Transform Message component.

To create the flow:

  1. Create a new Mule project in Studio.

  2. In the Mule Palette view, search for HTTP and select the Listener operation.

  3. Drag the Listener operation onto the canvas.

  4. In the Listener configuration, click + next to the Connector configuration field to add a global element.

  5. Accept the defaults.

  6. In the HTTP properties window, set the Path field to /createTeam.

Add the First Transform Message Component

The first Transform Message component creates a template for the input used to create the team:

  1. In the Mule Palette view, search for transform message.

  2. Drag the Transform Message component onto the canvas, to the right of the Listener component.

  3. In the Transform Message configuration, overlay the brackets in the Output section with this XML:

    {
	"template@odata.bind": "https://graph.microsoft.com/v1.0/teamsTemplates('standard')",
	description: message.attributes.queryParams.description,
	displayName: message.attributes.queryParams.displayName,
	"members":[
      {
        "@odata.type":"#microsoft.graph.aadUserConversationMember",
        "user@odata.bind":"https://graph.microsoft.com/v1.0/users('" ++ message.attributes.queryParams.user as String ++ "')",
         "roles":[
            "owner"
         ]
      }
}

Add the Create Team Operation

The Create team operation creates a new team based on user input:

  1. Drag the Create team operation onto the canvas, to the right of the Transform Message component.

  2. In the Create team configuration, click the Connector configuration dropdown and select Microsoft-Teams-Client-Config.

  3. Select Microsoft_Teams_Client_Credentials_Config as the global element type and click OK.

  4. Configure the following fields in the Create team properties window:

    Field Value

    Display Name

    Create team

    Connector Configuration

    OAuth_Client_Credentials_Config

    Message

    payload

Add the Second Transform Message Component

This Transform Message component converts the output of the Create team operation to JSON format.

  1. In the Mule Palette view, search for transform message:

  2. Drag the Transform Message component onto the canvas, to the right of the Listener component.

  3. Click the Transform Message component and set the output to application/json:

    %dw 2.0
output application/json

Retrieve the Team Properties and Relationships

Create a second flow to retrieve the properties and relationships for the new team. Use the Get Team operation in this flow:

Retrieve the team Flow
Figure 2. Use a flow like this one to retrieve the new team’s properties and relationships.

Retrieve the Team Members

Create a third flow to retrieve information about the members of the new team. Use the List team members operation in this flow:

Retrieve the team members flow
Figure 3. Use a flow like this one to retrieve information about team members.

Retrieve the Team Channels

Create a fourth flow to retrieve information about the channels used by the team. Use the List channels operation in this flow:

Retrieve the team channels flow
Figure 4. Use a flow like this one to retrieve the channels used by the new team.

Onboard a New Hire to the Team

Create a fifth flow to onboard a new hire to the team. Use the following operations in this flow:

  • Add team member to add a new member to the team

  • Create channel to create a new channel

  • Add channel member to add the new member to the newly created channel

  • Create message to create the welcome message

Onboarding a new hire flow
Figure 5. Use a flow like this one to onboard a new user.

Delete a Team Channel

Create a sixth flow to delete a channel. Use the Delete channel operation in this flow.

Delete a channel
Figure 6. Use a flow like this one to delete a channel.

Remove a Team Member

Create a seventh flow to remove a member from a team. Use the Remove team member operation in this flow.

Remove a team member
Figure 7. Use a flow like this one to remove a team member.

Run the App

To run the app:

  1. Right-click the project in Package Explorer and select Run As > Mule Application.

  2. After the app deploys, open a web browser.

  3. Enter the following URL to start the OAuth dance: http://localhost:8081/authorize.

  4. In the login screen, enter the login information used to access Microsoft Teams and click Login.

  5. Click Allow.

  6. Initiate a flow by entering the associated URL, as shown in the following table. If the URL has query parameters, ensure that you include the parameter values:

    Flow URL Notes

    Create a new team

    http://localhost:8081/createTeam?displayName={teamDisplayName}&description={teamDescription}&user={teamOwnerUser}

    Retrieve the team properties and relationships

    http://localhost:8081/getTeam?team={createdTeamId}

    Retrieve the team channels

    http://localhost:8081/listChannels

    Returns only the default channel because this example does not create channels.

    Onboard a new hire to the team

    http://localhost:8081/newHireFlow?channelName={channelName}&team={createdTeamId}&userToOnboard={userToBeOnboarded}&channelOwner={channelOwner}

    For the userToOnboard query parameter, specify a user who is not the channel owner. The JSON response contains the following welcome message:

    "content": "Welcome to the team {channelName}"

    Delete a team channel

    http://localhost:8081/deleteChannel?team={teamId}&channel={channelId}

    Remove a team member

    http://localhost:8081/removeTeamMembers?team={teamId}&member={membershipId}
