Azure Logic Apps

Logic Apps provides a rich set of connectors that let you integrate Azure services, SaaS applications, and on‑premises systems without writing code. In this tutorial, you’ll learn how to add a connector, configure authentication, and pass data between services.

Step 1 – Add a Trigger

Every Logic App starts with a trigger. For example, to run the workflow when a new email arrives in Outlook:

{
  "type": "Microsoft.Trigger",
  "name": "When_a_new_email_arrives_(V3)",
  "inputs": {
    "host": {
      "connection": {
        "name": "@parameters('$connections')['office365']['connectionId']"
      }
    },
    "parameters": {
      "folderPath": "Inbox"
    }
  }
}

Step 2 – Add an Action (Connect to Azure Storage)

After the trigger fires, store the email content in a Blob storage container:

{
  "type": "Microsoft.Actions",
  "name": "Create_blob_(V2)",
  "inputs": {
    "host": {
      "connection": {
        "name": "@parameters('$connections')['azureblob']['connectionId']"
      }
    },
    "parameters": {
      "folderPath": "emails",
      "fileName": "@{triggerOutputs()?['subject']}.txt",
      "content": "@{triggerBody()?['BodyPreview']}"
    }
  }
}

Step 3 – Configure Connections

Navigate to the API connections blade in the Azure portal and create the required connections. For Outlook and Azure Blob, the flow is:

1. Click + Create in the Connections list.
2. Select the connector (e.g., Office 365 Outlook).
3. Sign in with your account and grant permissions.
4. Repeat for Azure Blob Storage.

Step 4 – Test the Logic App

Send an email to the monitored mailbox. In the Azure portal, go to Runs history to see the execution details. The email body should appear as a blob in the emails container.
