August 05, 2022

In this Article, we’ll walkthrough how to Create Microsoft Teams from Template Teams using Microsoft Graph API in Power Automate

Pre-requisites:

• Teams created in Microsoft Teams which acts a Template
• Access to Azure AD to register App
• Access to Power Automate maker portal

Implementation Steps:

1. Register an application in Azure AD and add Teams/Group Permissions
2. Build flow in Power Automate that do the following,
   • Get Template Teams based on Template Teams Name
   • Send Graph API Request to Create Teams by Cloning the Template Teams
   • Check Teams Provisioning Status and ensure Teams created

Step 1: Register an application in Azure AD and add Teams/Group Permission

1. Go to Azure AD
2. Select App Registration > New Registration > Fill out the form

   

3. Copy Client ID and Tenant ID for later use

   

4. Generate Secret: Certificates & Secrets > New Client Secret > Fill Description > Add

   

5. Copy Secret (It won’t be visible later. So, note down for later use)

   

6. Select target API to add Permission: API Permissions > Add a Permission > Microsoft Graph

   

7. Add Permission: Application Permissions > (scroll down to Groups)Select Group.ReadWrite.All > Add Permissions

   

8. Grant Consent: Click ‘Grant admin consent for <tenant ID>’ (Status should turn to green)

   

Step 2: Build flow in Power Automate

1. Go to Power Automate maker portal : Go to Microsoft365 portal > Select Power Automate

   

2. Click New flow > Instant cloud flow

   

   Note : In automation scenarios, we need to use ‘Automated cloud flow’ with relevant trigger

3. Enter Flow name, Select Manually trigger a flow > Click Create

   

4. Create Trigger Input Parameters: Add Input

   

5. Add 2 input properties: Select Text(Input Type) > fill name and leave blank value

   1. Teams Template Name
   2. New Teams Name

6. Click New Step > Initialize variable (select from list of actions) > fill details. (Repeat this step and add variables as described in screenshot)

   

7. Click New Step > select Http > fill details and rename it as ‘GET Template Teams ID’

        "method": "GET",
        "uri": "https://graph.microsoft.com/v1.0/groups?$filter=displayName eq '@{triggerBody()['text']}'&$select=id",
        "authentication": {
            "type": "ActiveDirectoryOAuth",
            "authority": "@variables('varAuthorityUrl')",
            "tenant": "@variables('varTenantId')",
            "audience": "@variables('varGraphApiAudience')",
            "clientId": "@variables('varClientID')",
            "secret": "@variables('varClientSecret')"
        }
   

   

8. Run and check : Click Test (option exist at top right corner) > Manually > Test > Fill Details > Click Run flow > Done

   • Teams Template Name : Explore-Graph-API (Name of your Template Teams. This must have created as part of pre-requisites )
   • New Teams Name : Project-001 (or as you wish)

9. Succeeded Test run looks as below

   

10. Click GET Template Teams ID and Copy response body (which is required for next step)

    

11. Continue to edit the flow : Click Edit (option exist at top right corner)
12. Click New Step > parse JSON (select from list of actions) > Fill details and Rename it as ‘Parse JSON response of GET Template Teams ID’

    

    • Content - Body of ‘GET Template Teams ID’
    • Schema - Click ‘Generate from Sample’ > Paste the value which copied from previous step > Done

13. Click New Step > Compose (select from list of actions) > Fill Input field by pasting below formula in Expression textbox > Rename it as ‘Compose Template Teams ID’

    body('Parse_JSON_response_of_GET_Template_Teams_ID')?['value'][0]['id']
    

    

14. Clone Teams: Click New Step > Http (select from list of action) > fill details and Rename it as ‘Create Teams’

    "method": "POST",
    "uri": "https://graph.microsoft.com/v1.0/teams/@{outputs('Compose_Template_Teams_ID')}/clone",
    "body": {
            "displayName": "@triggerBody()['text_1']",
             "description": "created by cloning @{triggerBody()['text']}",
             "mailNickname": "@triggerBody()['text_1']",
             "partsToClone": "apps,tabs,settings,channels,members"
         },
         "authentication": {
             "type": "ActiveDirectoryOAuth",
             "authority": "@variables('varAuthorityUrl')",
             "tenant": "@variables('varTenantId')",
             "audience": "@variables('varGraphApiAudience')",
             "clientId": "@variables('varClientID')",
             "secret": "@variables('varClientSecret')"
         }
    

    

    NOTE: Clone request returns Response code 202, means request accepted. Provisioning might take more time depends on size of Template Teams. So, write more logic to check the provisioning status

15. Click New Step > Compose (select from list of actions) > Fill Input field by pasting below formula in Expression textbox > Rename it as ‘Compose URL to get Teams provision status’

    concat('https://graph.microsoft.com/v1.0',outputs('Create_Teams')['headers']?['Location'])
    

16. Click New Step > Initialize Variable (select from list of actions) > Fill details as mentioned below and Rename it as ‘Initialize Teams Provisioning Status’

    • Name : varTeamsProvisioningStatus
    • Type : String
    • Value : inProgress

17. Click New Step > Do until (select from list of actions) > Fill details and Rename it as ‘Do until Teams Provisioning Status to Succeeded’

    Condition :- ‘varTeamsProvisioningStatus’ is equal to ‘succeeded’

18. Add action inside Do until block: Click Add an Action > select Http > fill details and Rename it as ‘Get Teams provisioning status’

         "method": "GET",
         "uri": "@{outputs('Compose_URL_to_get_Teams_provision_status')}",
         "authentication": {
             "type": "ActiveDirectoryOAuth",
             "authority": "@variables('varAuthorityUrl')",
             "tenant": "@variables('varTenantId')",
             "audience": "@variables('varGraphApiAudience')",
             "clientId": "@variables('varClientID')",
             "secret": "@variables('varClientSecret')"
         }
    

    

19. Add action inside Do until block:Click Add an Action > select ‘Set Variable’ and Rename it as ‘Set Teams Provisioning status’ > Fill details as below and Click OK

    Name: varTeamsProvisioningStatus
    Value: body('Get_Teams_provisioning_status')?['status']
    

    

20. Add action inside Do until block: Click Add an Action > select ‘Condition’ and Rename it as ‘Check Teams Provisioning Status’

    Condition : ‘varTeamsProvisioningStatus’ is equal to ‘inProgress’

    • If Yes : Delay for 1 Minute
    • If No : no action

21. After adding the actions inside Do until block, it looks like this

    

22. Run and check : Click Test (option exist at top right corner) > Manually > Save & Test > Fill Details > Click Run flow > Done

    • Teams Template Name : Explore-Graph-API
    • New Teams Name : Project-001

    

23. Check your Teams

    

Things to consider:

It is allowed to create more Teams with same name. During the automation, check the exitance of teams with the display name before creating new Teams
