Fixed – 401 Unauthorized error while calling Dynamics 365 Web API


We were recently getting the below error while trying to call Dynamics 365 Web API through Postman.

“401 Unauthorized”

It turned out that we were using the incorrect Token.

To generate the correct token,

For OAuth 2.0 token endpoint (v1) Version 1

  • We need to specify resource with Dynamics 365 URL.


For OAuth 2.0 token endpoint (v2) Version 2

  • We need to specify scope with
    Dynamics 365 URL followed by .default instead of a resource.

The correct token results in the successful call to the Web API

How to – Check user’s access to a record – upcoming feature in Dynamics 365


Was going through the Model-Driven Apps documentation and found the below article

https://docs.microsoft.com/en-us/powerapps/user/access-checker

It talks about a Check access button on the command bar of a record which will list down all the rights/access/privileges on that particular record.

And also how the user has got those accesses, through security roles directly assigned or through the team the user belongs.

We can also check the access of the other users as well through user lookup.

How to – Embed Canvas App in an Iframe inside Dynamics 365


Canvas App can be easily embedded in a web site using the Iframe.

Say e.g. we have the following Canvas App to be embedded inside Dashboard in Dynamics 365

Save the app and navigate to Details

We can copy the Web link or App ID.

The URL Format –

https://apps.powerapps.com/play/[appId]

The other parameter that can be used are

source, tenantid, screencolor and any additional parameters

e.g.

https://apps.powerapps.com/play/[appId]?source=iframe&screenColor=rgba(120,110,55,1)&param1=value&param2=value 2

  • Here we have embedded it inside an Iframe component within the Dashboard

Publish the change and navigate to the Dashboard, we can see our Canvas App.

If the application is using Azure Active Directory-based authentication, the user will not be asked to sign-in again, else the user will be asked to Sign-in and will be able to access the app if it is shared with them.

Here we have embedded it inside an ASP.NET page, and we are asked to Sign-in.

After successful sign-in

Traffic information in the map component – 2020 Release Wave 2


The interactive Map component (preview) can now be enabled to show traffic information like traffic congestion, incidents, traffic flow using red, yellow, and green colors.

Before we can use the Map component (preview), we need to first enable it for the environment.

Navigate to the admin portal –

https://admin.powerplatform.microsoft.com/

Within features, enable the Geospatial services and save the setting.

Else we would be getting the below error while trying to add the map component to the canvas app screen.

Here we have added the map component.

And updated the default location.

Scrolling down within the properties pane, we can see the properties specific to traffic information.

  • Show traffic incidents – On / Off.
  • Traffic flow types – None, Relative, Relative Delay only.

Below is how it renders for different values for traffic flow types.

Traffic flow type = none

No data is shown

 Traffic flow type = relative

Relative data to the free-flow of the road

 Traffic flow type = relative-delay

Areas that are slower than average expected delay
