Power Automate: Sending Emails without User Context

This article helps us to understand the way to send emails without the user context. This could be applicable for applications, where consumers/users are non-licensed.  

This could be achieved with the help of few set of actions on Power Automate flow. Here Microsoft graph end points are used to send emails on power automate, based on application permissions. The app permission needs to be enabled on Azure AD app. 

Let us only look at the power automate configuration, instead of end-end business scenario. The following snapshot shows the actions.

Power Apps: Different type of Apps with Detailed Understanding

Power Apps provides options to create app based on the requirement and usage. There are three different type of apps available.
  • Canvas 
  • Model Driven  
  • Portal 

Power Apps with the above three type of apps, adds more value to the Microsoft power platform, along with Power Automate. With both of these services from power platform, some of the complex business scenarios could be achieved with no-code or less-code approach. You will get this fact at the end of this article.

Let us quickly understand these different types.

Canvas App

When power Apps was introduced few years ago, this was the only type available. This type provides options to customize the user experience. That means, you can build the app from scratch defining each and every aspect of it. That includes,
  • Design and UI elements –  
    • Helps creating screens and adding necessary controls with just drag and drop approach.  
    • Business logic can be  manipulated and achieved with functions/formulas with less-code or no-code scenarios. 
  • Data connectivity – 
    • There are default connectors available, providing flexibility to connect to multiple services without even writing code. This includes underlying common data service, and other SAAS services. 
    • On top of this, Power Automate provides greater flexibility in integrating the multiple services/systems data with no-code configurations. 
  • Users: 
    • This canvas type is available for Azure AD or external users. 
    • Only licensed users can only access the app. - The basic options available as of writing are for single app or multiple apps per user.

Model Driven PowerApp: 360 Degree View Dashboard to Monitor Data from External Systems (Azure AD and Azure Cosmos DB)

Problem: The business dealership information is being captured on multiple external systems. There is a need for business to capture 360° data view dashboard to keep track of information of dealers, sales data, and many other dealership information at one place. And this dashboard is for business users on the organization for monitoring.

Let us take an example of dealership architecture, where dealer identities/domain information are stored on external Azure AD, and basic details of dealership is stored on Azure Cosmos database.

Note: The dealership use case is an example for us to explore the possibilities. Similarly, this can be replaced with any other data model.

Design & Solution Considerations

The following elements/components are considered for building this solution.
  • Azure Cosmos Database, which holds dealership’s basic information 
  • Azure Active Directory, which holds the domain/identity information of dealership users [This is external/separate domain, holding only dealership users] 
  • Power Automate, to integrate and push the data to CRM system. 
  • Microsoft Common Data Service, which acts as intermediate storage and containing subsets of information from two other systems. [Azure Cosmos DB and Azure AD] 
  • Power Apps – model driven app, which has necessary dashboard for business users. 

The following shows high level design of 360 degree architecture, integrating data from multiple systems.
High level design for Dashboard providing 360 degree of dealership data
High level design for Dashboard providing 360 degree of dealership data

The following illustrates the design.
  • The necessary data model or entities are created on Microsoft CDS to capture the data from multiple system. For now in this usecase, let us focus on one entity, I.e., dealers.  
  • The flow configured on Power Automate runs as a scheduled job, to synchronize the data into CDS. Pulls minimal information from Azure AD and Azure Cosmos database, and synchronize the data subset into Microsoft CDS.  
  • Power Apps, which has views, forms and dashboards pulls and shows the information from entities, which is configured in the underlying CDS. 

Now let us get deeper into the solution, to see how these are configured.

Provision Private Channels on Microsoft Teams with Tabs

Let us understand how to auto-provision a private channel on Microsoft Teams, along with necessary tabs added on the private channel in an automated way.

Article: Private channel provisioning along with necessary tabs could automated with the help of Power Automate flow and Microsoft Graph API. Microsoft Graph API provides us the beta/major version of the graph endpoints to achieve the provisioning solution. Power Automate flow is configured with necessary HTTP requests for provisioning and automate the process.

The solution requires two major steps.
  • Creating Private Channel
  • Adding Tabs

Create Private Channel on Microsoft Teams 

At the time of writing this article, private channel creation endpoint is not available with major version (v1.0). Major version of graph endpoint, provides option to create a channel, but not private channels.
Content-type: application/json
{ "displayName": "Architecture Discussion", "description": "This channel is where we debate all future architecture plans" } 

The beta version of graph endpoint, provides option to create a private channel. The endpoint requires a payload to define the nature of channel and to add members with their roles. The following snapshot from Power Automate shows the way to create a private channel, with a member and their role.

Configure Azure AD end-user Authentication and Office 365 data access on Azure Health BOT Service via Graph API

Microsoft Health BOT Service is hosted on Azure, and is easily configurable solution that might meet multiple health-related BOT scenarios.

The scenario considered here in this article, helps us to understand how to enable end-user authentication on BOT Service to read Office 365 relevant data. For this POC, Azure AD authentication is considered. Azure AD authentication is best, only when the BOT service provider/organization manages their users entirely on Azure AD. If not the identity and authentication to be changed accordingly.

So in this article, let us understand how to enable end-user authentication on Azure Health BOT service using Azure AD, and read user profile information using Microsoft Graph API.

Enable Azure AD Authentication Flow using Azure AD App configuration

Create an application on Azure AD, and configure the following.
  • Set the required API permissions. In my case, only User.Read under Microsoft Graph delegated type.
  • Set oauth2AllowImplicitFlow to true, under Manifest section or platform configuration section.
  • Under platform configurations, configure the redirect URI ( for health BOT service authentication. 
  • Generate the secret key from certificates & secrets. (Dem81hW@h:Ia07Os/kQEzk-Cr48_SuLm)

Copy the client ID and client secret from this app, to be used in the next sections on Azure Health BOT service configurations.

Configure Azure AD Authentication on Health BOT service

From the health BOT service (<account-id>), navigate to integration -> authentication.

Authorization URL:<tenantname>
Access Token URL:<tenantname>

Add new authentication provider with the configurations below.

Azure Web App – Integrate Microsoft Teams Channel and show Conversation highlights with MS Graph API endpoints

This article helps you out integrating the Microsoft Teams channel data into custom web applications. Assume an use case, web application has channel mapping, where the app interface needs to show the highlights of latest conversations from respective team channels.

Currently the graph endpoint which exposes the channel messages is beta and available as protected endpoints.

Note: Microsoft Team restricts more sensitive data, and integrate the endpoints if there is a need. Please read out the following notes for the integration guidance.
  • This article little focuses on information about integrating protected APIs. As of today, Microsoft has restricted integrating some of their beta APIs. The protected endpoint list is shown here.
  • To enable the protected APIs for integration, you would need to reach out to Microsoft team for integrations. The request could be submitted through this form.
  • The request is generally reviewed, approved and enabled over a timeline mentioned in the article. 
  • The request form needs to be filled with tenant, Azure AD app (explained below) and other details. 
  • Once the request is approved, you will get a notification over email confirming the API enablement within specific timeline. 

Azure AD App Registration and Configuration

Before submitting the request, an Azure AD app needs to be registered on the tenant. The use case requires to get the channel conversations. So, the following snapshot shows the configured and granted permissions. Apart from this configuration, the other key parameters needs to be configured.
  • Enabling oAuth implicit flow. 
  • Enabling implicit tokens 
  • And providing redirect APIs.

Retrieve Office365 People data on MS Team Channels via Outgoing Webhook and Azure App Service

Here, let us see how office 365 people information can be integrated into Microsoft Teams, with the help of outgoing webhooks on Teams. The use case is to pull the people present at a location, on posting a message to a service from Microsoft Teams.  

This could be easily achieved with the help of outgoing webhook feature under teams. The webhook has to interact with a service to get data processed based on data posted. 

Why Outgoing Webhook?: The outgoing webhook is used here instead of incoming webhook, since the data needs to be retrieved only when it is required.

No BOT Framework, only Azure App Service: This article helps us to understand creating outgoing webhook services for Microsoft Teams, without creating BOT service/app. Here the intent of service is clear, so we are not leveraging the BOT framework, instead hosting a simple service with Azure web app. From azure web app, the people data is being pulled from Azure AD with the help of Microsoft Graph API.

Create an outgoing webhook for a Microsoft Team 

Locate a team under Microsoft Teams, and navigate to manage team. Under App, in the bottom right corner, you will find an outgoing webhook link. From the link, create a webhook.

Setting up Microsoft Teams Shifts Schedule Reminders

This article will help us to setup reminders for Shifts on Microsoft Teams using Power Automate. This will help to understand how shift reminders are triggered to shift owners a day before the shift schedules, as gentle reminders.

Before getting into implementation, we will see short introduction of Shifts app. Recently Microsoft has retired the Staffhub service, and Shift app is available as replacement and is available as an app on Microsoft Teams.

Microsoft Team's Shifts App

Shifts App, as quoted on Microsoft documentations: The Shifts app in Microsoft Teams keeps Firstline Workers connected and in sync. It's built mobile first for fast and effective time management and communication for teams.

Shifts app lets users on Microsoft Teams to create necessary shift schedules, and assign/share the schedules with teams. Once the schedule is created and shared on Teams, users will be able to view the schedules on their Teams login.
  • Currently, notifications are not working as expected. In my case, after sharing the schedule with a team, the notifications were not triggered to teams users. 
  • The shift schedule is not currently synced up with calendars. 
Hope the above drawbacks would be addressed in the near future by Microsoft product team.

This article helps us to understand a reminder notification requirement, which I came across recently. Let us look at how to trigger reminder notifications to respective schedule owners a day before the shift schedule.

Create a necessary shift schedules and share it with teams on Microsoft Teams interface.
