This is a sample application which demonstrates how to pin messages in chat using Graph api.

This is an sample application which displays all the pinned messages in group chat. It also demonstrates how to pin new message in the chat.

Key features

1. Pin new message in chat.

2. The pinned message will be shown in tab.

3. You can select different message from the list of messages. The message will be pinned in chat.

Prerequisites

• Microsoft Teams is installed and you have an account (not a guest account)
• NodeJS
• ngrok or equivalent tunneling solution
• M365 developer account or access to a Teams account with the appropriate permissions to install an app.

Run app locally

Register your Teams Auth SSO with Azure AD

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.io/{{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.io/[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.

13. 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 web.
  • Enter the redirect URI for the app in the following format: https://{Base_Url}/auth-end. This will be the page where a successful implicit grant flow will redirect the user.
• Enable implicit grant by checking the following boxes:
  ✔ ID Token
  ✔ Access Token

14. 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 env file.

To try this sample

Note these instructions are for running the sample on your local machine, the tunnelling solution is required because the Teams service needs to call into the app.

1. Clone the repository

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

2. Navigate to project

In the folder where repository is cloned navigate to samples/graph-pinned-messages/nodejs

3. Update the .env

Update configuration with the MicrosoftAppId, MicrosoftAppPassword and MicrosoftAppTenantId.

4. Run ngrok - point to port 3978

ngrok http -host-header=rewrite 3978

3. Install node modules and run server

Inside node js 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

npm install

npm start

3. Install node modules and run client

Navigate to client 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

npm start

4. Manually update the manifest.json

• Edit the manifest.json contained in the Manifest folder to replace your Base url wherever you see the place holder string <<BASE-URL>>. Also replace any random guid with the place holder <<APP-ID>>.
