Interaction with app

pinned-messages

Prerequisites

  • Microsoft Teams is installed and you have an account (not a guest account)
  • .NET 6.0 SDK. 
        # determine dotnet version
    dotnet --version
  • dev tunnel or ngrok latest version or equivalent tunneling solution
  • M365 developer account or access to a Teams account with the appropriate permissions to install an app.

Setup

1. Setup for App Registration

  1. Register a new application in the Azure Active Directory – App Registrations portal.
  2. Select New Registration and on the register an application page, set following values:
    • Set name to your app name.
    • Choose the supported account types (any account type will work)
    • Leave Redirect URI empty.
    • Choose Register.
  3. On the overview page, copy and save the Application (client) ID, Directory (tenant) ID. You’ll need those later when updating your Teams application manifest and in the appsettings.json.
  4. Under Manage, select Expose an API.
  5. Select the Set link to generate the Application ID URI in the form of api://{AppID}. Insert your fully qualified domain name (with a forward slash "/" appended to the end) between the double forward slashes and the GUID. The entire ID should have the form of: api://fully-qualified-domain-name/{AppID}
    • ex: api://%ngrokDomain%.ngrok-free.app/{{00000000-0000-0000-0000-000000000000}}.
  6. Select the Add a scope button. In the panel that opens, enter access_as_user as the Scope name.
  7. Set Who can consent? to Admins and users
  8. Fill in the fields for configuring the admin and user consent prompts with values that are appropriate for the access_as_user scope:
    • Admin consent title: Teams can access the user’s profile.
    • Admin consent description: Allows Teams to call the app’s web APIs as the current user.
    • User consent title: Teams can access the user profile and make requests on the user's behalf.
    • User consent description: Enable Teams to call this app’s APIs with the same rights as the user.
  9. Ensure that State is set to Enabled
  10. Select Add scope
    • The domain part of the Scope name displayed just below the text field should automatically match the Application ID URI set in the previous step, with /access_as_user appended to the end:
      • `api://[ngrokDomain].ngrok-free.app/[App-id]/access_as_user.
  11. In the Authorized client applications section, identify the applications that you want to authorize for your app’s web application. Each of the following IDs needs to be entered:
    • 1fec8e78-bce4-4aaf-ab1b-5451cc387264 (Teams mobile/desktop application)
    • 5e3ce6c0-2b1f-4285-8d4b-75ee78787346 (Teams web application)
  12. Navigate to API Permissions, and make sure to add the follow permissions:
  • Select Add a permission
  •  Select Microsoft Graph -> Delegated permissions.
    • Chat.Read
    • Chat.ReadWrite
    • ChatMessage.Send
  • Click on Add permissions. Please make sure to grant the admin consent for the required permissions.
  1. Navigate to Authentication If an app hasn't been granted IT admin consent, users will have to provide consent the first time they use an app.
  • Set a redirect URI:
    • Select Add a platform.
    • Select Single Page Application.
    • Enter the redirect URI for the app in the following format: https://{Base_Url_Domain}/auth-end. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your {Base_Url_Domain} will be1234.ngrok-free.app and if you are using dev tunnels then your domain will be 12345.devtunnels.ms.
  1. Navigate to the Certificates & secrets. In the Client secrets section, click on "+ New client secret". Add a description(Name of the secret) for the secret and select “Never” for Expires. Click "Add". Once the client secret is created, copy its value, it need to be placed in the appsettings.json.

2. Setup NGROK

  1. Run ngrok - point to port 3978

    ngrok http 3978 --host-header="localhost:3978"

    Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:

    devtunnel host -p 3978 --allow-anonymous
  • Once started you should see link https://41ed-abcd-e125.ngrok-free.app. Copy it, this is your baseUrl that will used as endpoint for Azure bot.

3. Setup for code

a. Clone the repository

git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

b. Launch Visual Studio

  • File -> Open -> Project/Solution
  • Navigate to folder where repository is cloned then samples/graph-pinned-messages/csharp/GraphPinnedMessage.sln

c. Update appsettings.json

Update configuration with the MicrosoftAppId, MicrosoftAppPassword, MicrosoftAppTenantId and ApplicationIdURIwith values generated in step 1 while doing App Registration.

d. Install node modules for client app.

Navigate to samples/graph-pinned-messages/csharp/GraphPinnedMessage/ClientApp folder, Open your local terminal and run the below command to install node modules. You can do the same in Visual studio code terminal by opening the project in Visual studio code

cd client
npm install

If you face any dependency error while installing node modules, try using below command

npm install --legacy-peer-deps
  1. After node modules are installed, inside visual studio run the solution by pressing F5.

4. Setup Manifest for Teams

  1. This step is specific to Teams.
    • Edit the manifest.json contained in the AppManifest folder to replace your Microsoft App Id (that was created when you registered your app earlier) everywhere you see the place holder string <<YOUR-MICROSOFT-APP-ID>> (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
    • Edit the manifest.json for configurationUrl inside configurableTabs . Replace {{BASE-URL-DOMAIN}} with your app's base Url domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your base url domain will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be 12345.devtunnels.ms.
    • Edit the manifest.json for validDomains with base Url domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your domain-name will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.
    • Zip up the contents of the AppManifest folder to create a manifest.zip (Make sure that zip file does not contains any subfolder otherwise you will get error while uploading your .zip package)
    • Upload the manifest.zip to Teams (In Teams Apps/Manage your apps click "Upload an app". Browse to and Open the .zip file. At the next dialog, click the Add button.)
    • Add the app to personal/team/groupChat scope (Supported scopes)

Running the sample

  1. Add the app in group scope. pinned-messages-install

  2. Install the configurable tab inside the group. pinned-messages-install

  3. Pin chat message pinned-messages

  4. Pinned Message will be shown in tab page. pinned-messages-details
