Upload and test the custom apps in Teams environment v4

  • Article

Important

We've introduced the Teams Toolkit v5 extension within Visual Studio Code. This version comes to you with many new app development features. We recommend that you use Teams Toolkit v5 for building your Teams app.

Teams Toolkit v4 extension will soon be deprecated.

After adding API connection, you can test API connection in the Teams Toolkit local environment and deploy your application to the cloud. In CI/CD pipeline, after set-up with different platform, you need to create Azure service principal to provision and deploy resources.

In this section, you'll learn:

Test API connection in local environment

The following steps help to test the API connection in the Teams Toolkit local environment:

  1. Run npm install

    Run npm install under bot or api folder to install added packages.

  2. Add API credentials to the local application settings

    Teams Toolkit doesn't ask for credentials, but it leaves placeholders in the local application settings file. Replace the placeholders with the appropriate credentials to access the API. The local application settings file is the .env.teamsfx.local file in the bot or api folder.

  3. Use the API client to make API requests

    Import the API client from the source code that needs access to the API:

    import { yourApiClient } from '{relative path to the generated file}'

  4. Generate http(s) requests to target API (with Axios)

    The generated API client is an Axios API client. Use the Axios client to make requests to the API.

    Note

    Axios is a popular nodejs package that helps you with http(s) requests. For more information on how to make http(s) requests, see Axios example documentation to learn how to make http(s).

Deploy your application to Azure

To deploy your application to Azure, you need to add the authentication to the application settings for the appropriate environment. For example, your API might have different credentials for dev and prod. Based on environment needs, configure Teams Toolkit.

Teams Toolkit configures your local environment. The bootstrapped sample code contains comments that tell you what app settings you need to configure. For more information on application settings, see Add app settings

Provision and deploy CI/CD resources

To provision and deploy resources targeting Azure inside CI/CD, you must create an Azure service principal for use.

Perform the following steps to create Azure service principals:

  1. Register a Microsoft Entra application in single tenant.
  2. Assign a role to your Microsoft Entra application to access your Azure subscription. The Contributor role is recommended.
  3. Create a new Microsoft Entra application secret.

Tip

Save your tenant id, application id (AZURE_SERVICE_PRINCIPAL_NAME), and the secret (AZURE_SERVICE_PRINCIPAL_PASSWORD) for future use.

For more information, see Azure service principals guidelines. The following are the three ways to create service principals:
