Hello Sahil , Welcome to MS Q&A

I think you can use Azure Event Grid. By subscribing to Blob storage events, you can set up a system that sends notifications to your application whenever a blob is created or modified. Here’s how you can do it:

1. Create a Blob Storage Account: First, ensure you have a Blob storage account set up in Azure.
2. Subscribe to Events: Navigate to your storage account in the Azure portal, select "Events" from the left menu, and create an event subscription. You will need to specify the endpoint where the events should be sent, such as a web app or an Azure Function.
3. Trigger an Event: When a blob is uploaded to the storage account, Event Grid will send an event to the specified endpoint, allowing your application to react accordingly.

This setup allows you to handle events asynchronously without the need for polling, making your application more efficient.

• Use Azure Event Grid to route Blob storage events to web endpoint (Azure portal)

Hi Sahil Kumar ,
Welcome to Microsoft Q&A Forum. Thanks for posting you query here!
To get a callback or notification from Azure when a blob is uploaded to a storage account, you can use Azure Event Grid. Here are the steps to set it up:

1. Create an Azure Storage Account: If you don't already have one, create a storage account in the Azure portal.
2. Enable Event Grid on the Storage Account:
   • Go to your storage account in the Azure portal.
   • Under the "Events" section, select "Event Grid".
   • Click on "Create Event Subscription".
3. Create an Event Subscription:
   • In the "Create Event Subscription" pane, provide the necessary details:
   • Name: Give your event subscription a name.
   • Event Schema: Choose "Event Grid Schema".
   • Event Types: Select the event types you want to subscribe to (e.g., BlobCreated).
   • Endpoint Type: Choose "Web Hook".
   • Endpoint: Enter the URL of your API endpoint that will handle the callback.
4. Configure Your API Endpoint:
   • Ensure your API endpoint is set up to receive and process the events from Event Grid.
   • Your endpoint should be able to handle HTTP POST requests and process the event data sent by Event Grid.

Upload a blob to your storage account and verify that your API endpoint receives the event notification.
