AI Builder In PowerApps – Business Card Reader Example

So a few days ago (Early June 2019), Microsoft started to roll out previews of the AI Builder in PowerApps.

What is AI Builder?

According to the Documentation (and it’s worth bearing in mind, that because this is in preview mode, the documentation may change), AI Builder is:


“A new Power Platform capability that allows you to easily automate processes and predict outcomes to help improve business performance. AI Builder is a turnkey solution that brings the power of Microsoft Artificial Intelligence through a point and click experience. Using AI Builder, you can add intelligence to your apps even if you have no coding or data science skills.”

As it stands right now, this is in preview, and you have to enable it in your PowerApps settings.

For this quick article I thought I would go through a really simple example of scanning a business card, and then creating a new Lead record in Dynamics 365.

Just worth saying at this point, that while the following example is simple, it does show a really good use of AI and Microsoft’s Cognitive services. OCR or Optical Character Recognition, has been around for many years, but in the example below, the AI is doing more than just converting an image in to text….. it’s then analysing that text and making a decision as to what it is…. so looking at a word, and deciding it is a first name as opposed to a last name or company name. Putting that sort of power in our hands is awesome, and will get better and better!

To start with, create a new Canvas app in PowerApps, and use the Phone layout. If you have enabled the AI Builder Preview, then you should see the options in the insert menu

AI Builder

Choose the Business Card Reader option. This will place the Business Card Reader component on the Screen

The Business Card Reader currently can extract the following if a Business Card is detected:

  • CleanedImage: The image after processing where the business card appears cropped and enhanced from the original image.
  • CompanyName: The company name in the business card, if found.
  • Department: The organization department found in the business card, if found.
  • Email: The contact email found in the business card if any.
  • FirstName: The contact first name in the business card, if found.
  • FullAddress: The contact full address in the business card, if found.
  • FullName: The contact full name in the business card, if found.
  • JobTitle: The contact job title in the business card, if found.
  • LastName: The contact last name in the business card, if found.
  • OriginalImage: The original image before processing.
  • Phone1: The first phone or fax number detected in the business card, if found.
  • Phone2: The second phone or fax number detected in the business card, if found.
  • Phone3: The third phone or fax number detected in the business card, if found.
  • Website: The website detected in the business card, if found.

I decided just to keep things nice and Simple for this demo, so just included the following fields that I would use to create a new Lead in Dynamics 365:

  • Company Name
  • First Name
  • Last Name
  • Email Address

I also included a text field that I would map over to the Description field in Dynamics (I’ll show you later how I configure the Microsoft Flow to concatenate the Company Name – Last name for the Topic on the Lead record.

The fields I added were Text Input fields, so If I needed to change anything on the captured Data I could.

The formula for each field just references the Business Card Reader Component Name and the field, so for Company Name it was

BusinessCardReader1.CompanyName

After you have completed these steps, Save and Publish your app. If you’ve followed all the steps above, then you should be able to open the App, Take a photo of a business card and after processing, retrieve the data in to the fields.

So the next stage is to grab that data from our app, and use it to create a new lead.

For this we need to trigger a flow from a button on our screen. I added a Button and called it “Submit to D365”

Once the Button is on the screen, it needs to trigger a flow, which we’ll create next. In the Action Tab of PowerApps, choose Flows, then click Create a new flow. This will open up the Flow designer, which should already have the connector to your PowerApp (Thus inheriting that the button will trigger it)

So in the image above, you’ll see that I have added the “Create a New Record” Action in the flow, and chosen the Org Name and Entity – Lead for this example.

What you’ll also notice is that In the right hand side, there are currently no fields available, but instead have the “Ask In PowerApps” option. This is so that the flow can grab the relevant fields from the App. So If I Choose the Last Name field in the Create a Record Activity then Ask in PowerApps, it will return a holding field for reference:

You’ll also see in the image above that I have concatenated some fields for the Topic.

Once you’ve done this….. Save your Flow and go back to the App. 

In the App, highlight your Submit button, and use the following formula

PowerAppsbutton.Run(Createanewrecord_LastName,Createanewrecord_CompanyName,Createanewrecord_Email,Createanewrecord_FirstName)

So this is launching the flow and grabbing the data from the APP

NOTE: Worth noting here, that you’ll need to change the names of the fields on the app to match the names above and in the flow – so add the Createanewrecord_ prefix)

If all looks good, you should have no red crosses, and your formula looks like this

So after that, Save and Publish you App and give it a go!

365Knowledge YouTube Channel Update

It’s been a number of years since 365Knowledge posted any videos on YouTube, so I thought it was time we started again.

Interestingly, although I had neglected the channel, the 6 videos had a total watch of over 13,000 views which is small in comparison to most channels, but still quite a number.

So……………Watch this space!

Create Dynamics 365 Records From Azure Service Bus Queue – Via Logic App

I wanted to put together a solution where an external system could send a JSON payload through an Azure Service Bus Queue, and a new record created in Dynamics 365.

There are no doubt better, or at least different ways to approach a scenario like this, but I wanted to brush up on some skills, so thought it was a nice use case, and one I will be needing soon for integrating an external Oracle system.

So, basically this is the running order of steps:

  • Create Azure Service Bus Queue
  • Create Logic  App
  • Test (Using Postman to send JSON messages)

So, nothing too complex, but just thinking about this sort of scenario a few years ago (not that many to be fair), would have required a fair amount more development skills, but pretty well all of the above can be achieved in a codeless manner. As I have said before, “Don’t use a Sledgehammer to crack a walnut”. I have also tried to add some links to useful references within this blog.

So firstly, setup an Azure Service bus, and make sure you note the Primary Connection string, Queue name, and primary key.

If you’re planning on using something like Postman to test, the you’ll need to create a SAS Key

Open up a Cloud Shell and use the following to create a SAS Key.

You’ll need the Service Bus URI and the Queue Name, as well as the policy name and Key.

[Reflection.Assembly]::LoadWithPartialName("System.Web")| out-null
$URI="myNamespace.servicebus.windows.net/myEventHub"
$Access_Policy_Name="RootManageSharedAccessKey"
$Access_Policy_Key="myPrimaryKey"
#Token expires now+300
$Expires=([DateTimeOffset]::Now.ToUnixTimeSeconds())+300
$SignatureString=[System.Web.HttpUtility]::UrlEncode($URI)+ "`n" + [string]$Expires
$HMAC = New-Object System.Security.Cryptography.HMACSHA256
$HMAC.key = [Text.Encoding]::ASCII.GetBytes($Access_Policy_Key)
$Signature = $HMAC.ComputeHash([Text.Encoding]::ASCII.GetBytes($SignatureString))
$Signature = [Convert]::ToBase64String($Signature)
$SASToken = "SharedAccessSignature sr=" + [System.Web.HttpUtility]::UrlEncode($URI) + "&sig=" + [System.Web.HttpUtility]::UrlEncode($Signature) + "&se=" + $Expires + "&skn=" + $Access_Policy_Name
$SASToken

To test the Service Bus Queue I used Postman. You can add a number of useful Postman collections for Azure from Ludvig Falck on GitHub

There’s a few steps then in Postman to setup the parameters, Headers and Body (I just setup a really simple JSON payload as you can see).

Parameters

Add queueName as a Key and the queue name as the Value

Headers

For the Headers, you’ll need the SAS key you generated earlier.

Body

For the body, I just used a really simple payload

{
"email":"me@me.com"	,
"first":"John",
"last":"Smith"
}

Once this is completed, you should be able to hit “Send” and see the message being created in the Azure Service Bus Queue

Next step is to grab that message from Service Bus, and use it to create a Record in this case.

I decided to use Logic Apps as opposed to Flow, just to keep everything in Azure (although technically it’s all in Azure, but you get what I mean).

So this is the basic flow:

It’s pretty easy to follow. When a message is received in the Queue, grab it, Parse the JSON, use the data to create a record, then complete that message in the Queue.

One thing to bear in mind is that the JSON payload will need to be decoded to then be used in the creation of a Dynamics Record. In the “Content” field of the Parse JSON action, add this expression:

decodeBase64(triggerBody()?[‘ContentData’])

You’ll also need to add the JSON Schema. For the example Payload I used this:

{
    "properties": {
        "email": {
            "type": "string"
        },
        "first": {
            "type": "string"
        },
        "last": {
            "type": "string"
        }
    },
   
}

Once this is all done, Save the Logic app and Run it. If you’ve followed all the steps, sending a JSON payload from Postman should create a record in Dynamics.

Fun with Microsoft Flow, What3Words and Flic Button

There’s some really cool IOT stuff going on, and its getting easier to get involved and have a go.

I thought in this blog I would have a play with a couple of tools and see what we could do. Hopefully it’ll inspire you to have a go and improve!

For this article I am going to use:

  • Microsoft Flow
  • What3Words 
  • Flic

Before I go any further, lets just have a quick overview of these tools.

Microsoft Flow

Microsoft Flow is a tool that can integrate cloud-based apps and services so they interact with each other seamlessly. According to Microsoft, this cloud-based tool improves efficiency and productivity by enabling virtually anyone in an organization to automate many tedious and time-consuming business tasks and processes without developer intervention.

What3Words

what3words provides a precise and incredibly simple way to talk about location. We have divided the world into a grid of 3m x 3m squares and assigned each one a unique 3 word address.

Flic

Flic Buttons are a Smart Button that can be linked to a number of services. The button can be programmed to perform actions via an app or a hub, and can even trigger Microsoft Flows

I know with the Flic button a message with your coordinates can be sent, so I was interested to see if we could Parse that message through Microsoft Flow, run it through the What3Words API then action something with the results.

The resulting flow takes looks like this:

So lets run through it.

Theres a couple of things you need to do with the Flic button to set this up. 

In the Flic App on your phone or other device, you need to setup your connection to Microsoft Flow, and its really important that you choose to send location data:

Once this is done, log in to Microsoft Flow and create a new flow from Blank. You will then be able to add a Flic button as a trigger – the first time you do this, you’ll need to add your Flic account as a connection. You’ll then get to choose which button and which action

Next add an HTTP action. If your connection to Flic is successful, then you’ll have the output from the button press as options to feed in to your HTTP (in this case it is to access the What3Words API ( this is assuming you have already signed up to the What3Words API here and have an API key.

So here we have added the What3Words URI, and as you’ll see added the output from the Flic button as the coordinates. You’ll also need to add your API key as shown in the URI after &Key= and in the Value field.

Once this is completed, the returning JSON needs to be Parsed, so add the Parse JSON action. 

For the Schema, I used the “Use Sample Payload” option and the example on the What3Words Documentation here but just in case, here it is:

{
    "country": "GB",
    "square": {
        "southwest": {
            "lng": -0.195543,
            "lat": 51.520833
        },
        "northeast": {
            "lng": -0.195499,
            "lat": 51.52086
        }
    },
    "nearestPlace": "Bayswater, London",
    "coordinates": {
        "lng": -0.195521,
        "lat": 51.520847
    },
    "words": "filled.count.soap",
    "language": "en",
    "map": "https://w3w.co/filled.count.soap"
}                           

Finally, for this example I took the Parsed data, and added it to an email, but you could just as easily create a record in Dynamics 365 etc

And that should be it! If all works you’ll get lots of lovely ticks on your flow, and an email with your 3 word location, and a link to the map:

The possibilities are endless with these sort of tools. The whole process took less than an hour, and the only “Code” was the JSON payload that I copied and pasted!

Have a go.

Microsoft AZ-900 Certification

I’m pleased to say I have just passed the AZ-900 exam.

Although my main area of expertise is and always has been Dynamics 365 (CRM), I find myself getting more and more involved with the wider Microsoft Business Solutions Ecosystem, and that includes Azure. 

Whether its Logic Apps for workflow, or Service Bus for integration, I find most weeks I’m delving in to Azure.

For those thinking of taking the exam, I have to say I didn’t find it too difficult, and there are so many resources available to make sure you’re up to speed.

As a starting point, it’s always worth checking out the  details of what you’ll be examined on. for AZ-900, the details can be found here 

If you want some great training, and have a limited budget, I cannot recommend Microsoft Learn highly enough – Partly because it’s free, but mostly because it’s awesome! and getting better almost daily.

You Say Flow, I Say Logic Apps

I’ve been using Flow for quite a while, but recently started utilising Azure Logic Apps for some pieces of work. On one of the forums I frequent, someone asked the question “What’s the difference between Flow and Logic Apps”.

Well the quick and simple answer is that in a lot of ways, they’re the same thing……

However, that’s not the real answer or the complete picture. There are a few differences that might help you decide which to use in specific circumstances.

There’s a really good overview of the similarities and differences here, but it’s summed up nicely by this:


Microsoft Flow and Logic Apps are both designer-first integration services that can create workflows. Both services integrate with various SaaS and enterprise applications.
Microsoft Flow is built on top of Logic Apps. They share the same workflow designer and the same connectors.
Microsoft Flow empowers any office worker to perform simple integrations (for example, an approval process on a SharePoint Document Library) without going through developers or IT. Logic Apps can also enable advanced integrations (for example, B2B processes) where enterprise-level Azure DevOps and security practices are required. It’s typical for a business workflow to grow in complexity over time. Accordingly, you can start with a flow at first, and then convert it to a logic app as needed.

There’s loads of resources available to help get started, and decide which way to go. Here’s a couple of quick summaries

As I have mentioned before, Microsoft Learn has some great resources, and there is a really good Flow Learning Path to get you started. Nothing as yet on Learn for Logic Apps, but I’m sure there will be soon.

For me, when I looked at an integration with an external API, to be used across the whole enterprise, I decided to base it on Logic Apps. Whereas when I wanted a small solution to move attachments from Dynamics 365 to OneDrive (on my own companies Dynamics 365 instance) Flow was fine.

As we move to a more Serverless architecture, SaaS and PaaS solutions like Flow and Logic Apps are giving the power of integration and communication back in to the hands of the Power User, and not just the remit of the coder. The turn around and potential for Tech Debt is reduced (in my opinion), and is a very exciting step forward.
