[Exploration] Dynamics CRM Azure-aware plug-in + Azure Queue + Power Automate

Do you know the Azure-aware plugin? In short, we can create a simple plugin that invokes Azure Service Bus that enables us to do the Publisher-Subscriber model. In this blog post, we will try to make Azure Service Bus, Dynamics CRM Service Endpoint, and CRM Plugin for creating the queue. While for the processing part (subscriber), we will create Cloud Flow that will listen to the queue + insert a row on the google sheet.

Creating Azure Service Bus

You can go to your portal.azure.com > Service Bus > click the Create button. On that page, you can fill in the Subscription, create/select the Resource group, fill the Namespace, set the Location, and set the Pricing tier (I choose Basic for the demonstration purpose which is the cheapest tier). After that, you can hit the Review+create button and proceed to create the resource.

Create Service Bus

Then, you can go to Shared access policies blade > click Add button. The purpose of this is for making a new SAS Policy (try to avoid using the created one because the RootManageSharedAccessKey got Manage, Send, and the Listen claims). You can give the Policy name, and check for Send and Listen > click the Create button. 

Create Shared Access Policy

After it was created, you can copy the Primary Connection String for the future step.

Copy the Primary Connection String for future use

The last part is to set up the queue. You can go to the Entities > Queues blade > click the Queue button. Give the Name as queue1, and for the rest of the properties, I will not change it. Then you can click the Create button.

Create Queue

Creating New Service Endpoint In Dynamics CRM

Connect to your Plugin Registration Tool > Register > Register New Service Endpoint. Once the dialog comes out, you can paste the Primary Connection String from the previous step.

Register New Service Endpoint

In the next step, you need to fill in the Queue Name (queue1), change the Message Format to JSON. Then you can click the Save button.

Set Service Endpoint

After you save it, then what you need to do is to get the ServiceEndpointId. To do this, you can open any CRM form, then you can open developer tools (F12). Then you can run this command:

Xrm.WebApi.retrieveMultipleRecords('serviceendpoint', '?$select=name,description,serviceendpointid').then(result => console.log(result))

Once you run that command, you can find and select the Service Endpoint that you created before, copy the Id and save it for the next step.

Get ServiceEndpointId

Create Dynamics CRM Plugin

For this step, I’d like to use Microsoft Power Platform CLI. You always can execute the command “pac plugin create” on the folder that you wanted, and wait until the command finish. Once you open the .csproj, then you can update the Plugin1.cs as below:

using Microsoft.Xrm.Sdk;
using System;
namespace DemoPlugin
{
    public class Plugin1 : PluginBase
    {
        private readonly string _unsecureConfiguration;
        public Plugin1(string unsecureConfiguration, string secureConfiguration)
            : base(typeof(Plugin1))
        {
            _unsecureConfiguration = unsecureConfiguration;
        }
        protected override void ExecuteCdsPlugin(ILocalPluginContext localPluginContext)
        {
            if (localPluginContext == null)
            {
                throw new ArgumentNullException("localPluginContext");
            }
            var endpointRef =
                new EntityReference("serviceendpoint", new Guid(_unsecureConfiguration));
            localPluginContext.NotificationService.Execute(endpointRef, localPluginContext.PluginExecutionContext);
        }
    }
}

The code is pretty simple, we will receive the unsecureConfiguration which will be the serviceEndpointId. In ExecuteCdsPlugin, we only need to create the Azure queue using the command “localPluginContext.NotificationService.Execute(endpointRef, localPluginContext.PluginExecutionContext)“.

In the next step, you can build it and register the plugin using Plugin Registration Tool. Here is my setup:

Register new plugin step

The best way in my opinion to call this function is on the Asynchronous mode. Because actually what we want to do is to fire and forget about it. But you always can set the plugin step in the Synchronous mode.

From this step, you can try to invoke it (we already cover our setting to Publisher model). We can verify the result by updating an account (from Dynamics CRM Screen), then go to the portal.azure.com > go to queue1 > Service Bus Explorer (preview) blade > go to Receive tab > you will see there is 1 Active Message that you can receive > click the Receive button and you can inspect the result.

Verify the Publisher result

Power Automate as Subscriber Model

The last part is to listen to the queue that we already created. For the demonstration purpose, I will create a google sheet like the below:

Google Sheet Content

For the trigger, search Service Bus > choose When one or more messages arrive in queue (auto-complete). The purpose of this is to make sure the message is deleted from the queue instantly. For the connection string, you can paste the Primary Connection String from the previous step, name the connection string. Then you can set up the rest of the flow like below:

Flow Steps #1

Below is the response from the first step (you can use the below result as Generate from sample in the next step):

Below is the full demo when we run it from CRM + the result in the google sheet:

Demo time

In the google sheet, the Message is automatically encoded as base64String. So if you want to get the content, you will need to decode it.

Summary

I think this method is way more complex compared to using the Webhook that you can see from this blogpost. But as a Consultant/Developer, this is a good alternative to know.

Updated per 23 November 2021. Here are Bill Blancett‘s recommendations on how to choose Service Bus/Webhook:

  1. Hey Temmy! Bill here. Once again an excellent article that I will keep as a reference. Just to add a little more info to help guide decisions on whether to use webhooks or service endpoints for integrations, from Microsoft docs:

    https://docs.microsoft.com/en-us/learn/modules/integrate-common-data-service-azure-solutions/4-webhooks

    “ Service Bus or Webhook
    Consider using Azure Service Bus when:
    * High scale asynchronous processing/queueing is a requirement.
    * Multiple subscribers might be needed to consume a given Dataverse event.
    * You want to govern your integration architecture in a centralized location.
    Consider using webhooks when:
    * Synchronous processing against an external system is required as part of your process (Dataverse only supports asynchronous processing against Service Bus Endpoints).
    * The external operation that you are performing needs to occur immediately.
    * You want the entire transaction to fail unless the webhook payload is successfully processed by the external service.
    * A third-party Web API endpoint already exists that you want to use for integration purposes.
    * SAS authentication isn’t preferred and/or feasible (webhooks support authentication through authentication headers and query string parameter keys).”

    I’ve tended to use service endpoints for complex integrations with external in-house systems such erp’s etc. I’ve tended to use webhooks on much simpler one off integrations.
