Azure Service Bus Component

Interact with message queues and publish-subscribe topics (in a namespace)

Component key: azureServiceBus


Azure Service Bus is a fully managed enterprise message broker with message queues and publish-subscribe topics (in a namespace).


Connection String

Connection String

The Connection String authentication method is required for any integrations using the following actions:

  1. Send Messages from Queue
  2. Receive Messages from Queue

Additionally, in an integration, ensure when using these actions, the connection is configured to the Connection String authentication type.

Creating a new namespace automatically generates an initial Shared Access Signature (SAS) policy with primary and secondary keys, and primary and secondary connection strings that each grant full control over all aspects of the namespace. See Service Bus authentication and authorization for information about how to create rules with more constrained rights for regular senders and receivers.

A client can use the connection string to connect to the Service Bus namespace. To copy the primary connection string for your namespace, follow these steps:

  1. On the Service Bus Namespace page, select Shared access policies on the left menu.
  2. On the Shared access policies page, select RootManageSharedAccessKey.

In the Policy: RootManageSharedAccessKey window, select the copy button next to Primary Connection String, to copy the connection string to your clipboard for later use. Paste this value into the connection configuration of your Prismatic integration.

OAuth 2.0

Azure Service Bus uses OAuth 2.0 Authentication to authenticate the security principal (a user, a group, or service principal) running the application. Create and Register your Microsoft application with an Azure AD tenant. For more information refer to

The first step in using Azure AD to authorize Service Bus entities is registering your client application with an Azure AD tenant from the Azure portal

Menu > All Services > Azure Active Directory

  • Select Add > App registration
  • Name the App and set the Supported Account types to 'Accounts in any organizational directory (Any Azure AD directory - Multitenant)'.
  • In Redirect URI set the first field to “Web”. In the second field enter and select Register.

Create a client Secret

  • Navigate to your app registration in the Azure portal if you aren't already on the page.
  • Select Certificates & secrets on the left menu.
  • Under Client secrets, select New client secret to create a new secret.

Set the Permissions to the Service Bus API

  • If your application is a console application, you must register a native application and add API permissions for Microsoft.ServiceBus to the required permissions set. Native applications also need a redirect-uri in Azure AD, which serves as an identifier; the URI doesn't need to be a network destination. Use for this example, because the sample code already uses that URI.

Assign Azure roles using the Azure portal

Now, configure the OAuth 2.0 connection in Prismatic. Add an Azure Service Bus OAuth 2.0 Connection config variable:

  • Use the Application (client) ID value for the Client ID field.
  • Use the Client Secret for the same named field.
  • If you didn't select Multitenant when creating the Azure application, you will need to replace the Authorize URL and Token URL with ones specific to your tenant.

Save your integration and you should be able to authenticate a user through Azure Service Bus with OAuth 2.0.



Receive and validate webhook requests from Azure Service Bus for webhooks you configure. | key: subscriptionMessageWebhook

To trigger webhook calls within Service Bus, you need to make use of Azure Event Grid and Logic Apps. Follow these steps to build the webhook integration:

  1. Register Microsoft.EventGrid resource provider to the subscription:

    • Navigate to Azure account subscriptions.
    • Open the subscription settings.
    • Go to Resource Providers.
    • Register Microsoft.EventGrid resource.
  2. Create a Service Bus namespace: Create a Service Bus Namespace

  3. Receive messages by using Logic Apps: Receive Messages by Using Logic Apps

  4. Add a step to receive messages from Service Bus via Event Grid: Add a Step to Receive Messages from Service Bus via Event Grid

  5. Add a foreach loop: Add a Foreach Loop

  6. Add an HTTP action to post to Prismatic integration trigger:

  • Within the For Each loop, select "Add an action."
  • In the "Search connectors and actions" text box, enter "HTTP."
  • Select the HTTP action.
  • Select POST for Method.
  • Add the Prismatic Integration flow URL to the URI Input.
  • For the Body, add this expression: base64ToString(items('For_each')?['ContentData']).
  1. Add another action in the foreach loop to complete the message: Add Another Action in the Foreach Loop to Complete the Message

To test the webhook, send a message to the Topic Subscription using Service Bus Explorer. This should trigger the integration with Prismatic.
