Logic app with service bus example
A Logic App is a serverless workflow automation service provided by Microsoft Azure that allows you to create workflows and integrate various services and systems. You can easily integrate a Logic App with Azure Service Bus to perform actions based on messages in a Service Bus queue or topic. Here's an example of how to create a Logic App that interacts with Azure Service Bus:
**Scenario:** Let's create a Logic App that listens to a Service Bus queue and sends an email notification whenever a new message arrives in the queue.
**Prerequisites:**
- An Azure subscription.
- An Azure Service Bus namespace with a queue.
- An Office 365 or Outlook.com email account for sending notifications.
**Step 1: Create a Logic App**
1. Go to the [Azure Portal](https://portal.azure.com/).
2. Click on "Create a resource" and search for "Logic App." Click on "Logic App" in the results, and then click the "Create" button.
3. Configure the Logic App settings, such as the resource group, name, location, and tags.
4. Click "Review + Create" and then "Create" to deploy the Logic App.
**Step 2: Create a Trigger for Service Bus Queue**
1. After the Logic App is created, go to the Logic App Designer.
2. Search for "Service Bus" in the triggers section, and select "When a message is received in a queue (auto-complete)." This will be your trigger.
3. Sign in to your Azure account and configure the connection to your Service Bus namespace and specify the queue name.
4. Save the connection settings.
**Step 3: Define the Action**
1. After configuring the trigger, you can now define what action to take when a new message arrives in the queue.
2. Search for "Office 365 Outlook" in the actions section, and select an action like "Send an email (V2)" or "Send an email."
3. Sign in to your Office 365 or Outlook.com account and configure the email details, such as recipient, subject, and body. You can use dynamic content from the Service Bus trigger to populate email details.
4. Save the action settings.
**Step 4: Save and Enable the Logic App**
1. Save your Logic App workflow.
2. Enable the Logic App by clicking the "Run" button.
**Step 5: Testing**
Now, whenever a new message is added to the Service Bus queue you specified, your Logic App will trigger, and an email notification will be sent using the action you defined.
Remember to configure appropriate error handling and logging based on your requirements to ensure the reliability of your workflow.
This example demonstrates a simple integration between a Logic App and Azure Service Bus. You can extend this to include more complex workflows or integrate with other services as needed for your specific use case.
