D365, Flow and Twilio – Part 2

In my previous post I walked through the process of setting up your Twilio account to provide two factor authentication for registering with a Microsoft D365 portal. In this part I will show you how to verify that the verification code is correct. This post assumes you have created a page that can be used to enter the verification code you requested in the previous post and the verification code is sent to the D365 Contact record.

The first step is to create a trigger to do the verification check when the D365 Contact record is updated. We only want the verification to be performed under specific circumstances; In this case we put a condition to check the field we are storing the verification code in has a value and the Mobile Phone Confirmed field is currently false. For the purposes of the demo I am using the Fax field to store the verification code but you can create your own custom field to hold the code.

Step-1

If the Contact record is being updated for some other reason then the verification is not performed and the Flow just exits. If we are doing a Mobile Phone verification then we need to generate a GET request to the Twilio. Using this API we need to provide a couple of header values. The first is normal Content-type (application/json) and the important one is the X-Authy-API-Key which is available in the General Settings of your Verify Project.

Step-2

The dynamic values we pass to the API are the Mobile Phone and Fax (Verification Code) from the Contact record. The GET request will return a response that we parse using the Parse JSON Action. To fill out the Schema box I put the request we created (above) into Postman to get the response. Selecting the Use sample payload to generate schema option I was able to paste in the response and generate the schema.

Step-3a

For the Content field we just use the Body of the response we receive from the HTTP GET request.

Step-3

The next step is to check what response we have received as a Flow Condition so we can determine whether to update the record.

Step-4

Again, using the response from Postman you can determine what key value pairs are returned from the GET request. The screenshot below shows an example of a failure (Status: 404 Not Found) but the structure of the response is still the same as a successful response.

Step-4a

If the Condition has success equal to true, then we can update the Contact record to confirm the mobile phone number has been confirmed. Click on the Show advanced options to find the relevant field.

Step-5

Step-5a

We have now completed the steps of using Microsoft Flow and Twilio to confirm the mobile phone number for a Contact within the D365 Portal.
