Graph Bot Alexa Skill

Table of contents


This sample project demonstrates how to use Amazon Alexa to send email using the Microsoft Graph JavaScript SDK to work with data returned by Microsoft Graph. This sample creates a custom Alexa skill which will allow you to use your voice to interact with Microsoft Graph.

The sample uses the Azure AD v2.0 endpoint, which enables developers to write a single code flow that handles authentication for both users' work or school (Azure Active Directory) or personal (Microsoft) accounts, including Office 365,, and OneDrive accounts.

Using an Amazon Echo device or the Echo Simulator you can send an email with your voice using the command "Alexa, ask Graph Connect to send mail".


This sample requires the following:

Build and package the code for your skill

In this sample, the bot is written in Node.js. To prepare the code package for deployment, use the following steps to download dependencies and create a .zip file.

Building the Bot

  1. Download or clone the Microsoft Graph Alexa Connect Node Sample.

  2. Install the dependencies by running the following command:

    npm install
  3. Optionally, you can open the sample solution in Visual Studio Code to understand the how the bot works. Visual Studio Code can be used on either Windows or a Mac. Run the following command from the terminal or command window. Note the period at the end.

    code .
  4. Prepare the node package for deployment by zipping the source files. On the Mac using the terminal, run the following command from the folder containing the index.js. On Windows use the File Explorer content menu to send to a compressed folder.

Note: The zip file will only contain the index.js and emailHelper.js at the root and the node_modules folder, which contains all the npm packages.

zip -r index.js emailHelper.js node_modules/

In the Deploy the Skill section you will learn how to deploy this node zip package to a hosting provider, like AWS Lambda.

Code Highlights

  • The main skill code is located in the index.js file. This contains the main entry point which is called from the Echo device. In addition to passing the intent and the slot values, the OAuth 2 bearer token will also be passed to your code on every intent. Later in the Create the Alexa custom skill section you will link the skill with Active Directory. Once the account is linked and authenticated, the bearer token will be passed on every call; you only need to provide it to the Microsoft Graph JavaScript library to make calls on the Graph.

  • The sample uses the JavaScript SDK library to make it easy to call the Microsoft Graph. The library is distributed as an npm package.

  • The emailHelper.js file helps format the message to pass to the sendMail Graph API call.

To learn more about creating Alexa Skills vist the Amazon Developer portal.

##Deploy the code package for your skill## Now that you have the code for the skill packaged you need to deploy it to a host server. In this sample you will use Amazon Lambda to host the node code.

Note: If you are new to Lambda functions you can follow these more detailed steps for Creating an AWS Lambda Function for a Custom Skill.

  1. Login to the AWS Management Console for Lambda.
  2. Click Create a Lambda Function to create a new function.
  3. On the Select a Blueprint step, Click Blank Function to skip using a Blueprint.
  4. Create a Trigger by clicking on the dotted square. Choose Alexa Skills Kit from the dropdown menu.

  2. Under Redirect URIs, enter the first redirect URL, In a later step from the Alexa skill portal, you will retrieve the other two redirect URLs from the Redirect URLs field. The URLs will be in a format similar to these: _ and .

Note: Currently, there is a temporary limitation with Azure AD where you also need to add the root domain, in this case, if your redirect URLs use a subdomains. Read more details about Azure AD v2 endpoints and redirect URL retrictions.

Note: The redirect URLs are located on your Alexa skill page's Configuration section under Account Linking. The Alexa Skill provides 2 URLs. You will need to add both URLs, one is for North American devices and one is for European devices. Once you create your skill later, remember to return and replace the temporary redirect URL with the actual ones.

  1. Select Next to go to the Configuration section.


The Configuration section is where you will define 2 important parts of your skill, the EndPoint and the Linked Account.


The EndPoint is a URL reference to the code for your skill. In this sample you will use Amazon's Lambda to host the code, but this can also be hosted on any HTTPS reachable endpoint.

  1. Set the Service Endpoint Type to AWS Lambda ARN (Amazon Resource Name). You can also choose HTTPS if you would like to host your skill code on Microsoft Azure. For this sample you will use AWS. An Azure step-by-step readme will follow in the near future.
  2. Set the AWS Lambda ARN to North America.
  3. Set the ARN to your Lambda function. Enter the ARN from your Lambda function that you created earlier.

The Lambda function is up and running

Account Linking

Authentication for Alexa skills are handled using account linking. When your skill is enabled the user will execute the OAuth 2.0 authentication flow in the browser. The security tokens will be managed by Amazon. When your skill is invoked, the authentication token will be passed to your skill code.

  1. Select Yes to: Do you allow users to create an account or link to an existing account with you?

Note: At this point you will need to jump out to the Register an application section of this readme. You will basically need to do these two sections in parallel. Open a new browser window to make it easy to switch back and forth.

  1. Set Authorization URL to

    Note: This authorization url will allow only work or school accounts. There is currently an issue in AD where all MSA accounts are not supportted. If you want to allow both work or school accounts and MSA accounts use this endpoint:

  2. Client Id will be the value of your Application Id from the Microsoft Application Registration Portal, as described in the Register an application section.

  3. Enter URLs for each domain in your authentication flow. For example here are the ones to login in using my corporate credentials or my Microsoft Account (MSA),like hotmail, credentials. I have also included the URLs for the Chinese and German Azure datacenters. If you are using a custom domain you will need to add those as well. Enter the following domain URLs for the whitelist.

  4. For Scope, add the following scopes.

    • offline_access - This tells Azure AD to return a refresh token. This is required for all skills regardless of what other scopes are required.
    • - read-only access to the user profile.
    • - read-only access to read mail.
    • mail.send - permission to send mail.
  5. Copy a Redirect URL into your Azure AD skill registion that you completed earlier.

  6. Set Authorization Grant Type to Auth Code Grant.

  7. Set Access Token URI to

    Note: This authorization url will allow only work or school accounts. There is currently an issue in AD where all MSA accounts are not supportted. If you want to allow both work or school accounts and MSA accounts use this endpoint:

  8. The Client Secret will be the secret generated in the Register an app in Azure AD section.

  9. Set the Client Authentication Scheme to Credentials in the request body.

Alexa Skill Configuration Page

  1. Enter a Privacy Policy URL. For example you can use as a placeholder for the sample.
  2. Click Next to go to the Test section.

Note: Your skill is ready to test, jump ahead to the Test section of this readme.

Link your Account

Once you enable account linking on your skill you will need to enable the skill and link the account. This can be done on either the Alexa app for iOS, Android, or the web.

  1. Open the web Alexa App
  2. Click on Skills on the left menu to open the Alexa Skills store.
  3. Click on Your Skills on the top right to list just the skills you have enabled.
  4. Browse the list of your skills and click on the Graph Connect skill.

Test the sample

You can test your custom skill from within the Alexa skill developer console. This will enable you to see the actual request and response to your service.

Note: Before you can test you will need to link your account section of this readme. If you have not already created the zip package to deploy your code, do this step now.

  1. Select the Test tab.
  2. Set the Enter Utterance field to "send mail".
  3. Select Ask Graph Connect Skill to make the request.

Alexa Skill Test Page

Run the sample in the Echo simulator

After you have verified that everything is working in the Amazon developer console, you can test it on an actual Amazon Echo device or using the Echo simulator.

If you are using an actual Echo device that is registered using the same account as your developer account then it is already available. Say "Alexa, ask Graph Connect to send mail."

If you are using the simulator use the following steps:

  1. Open
  2. Select Login with Amazon and login with the same account you are using to develop the sample.
  3. Wait for the simulator to indicate it's ready.
  4. Click and hold the microphone icon and say "ask Graph Connect to send mail".

Note: The simulator only works with a limited number of browsers like Chrome.
