Quickstart: Handle Advanced Messaging events

  • Article

Azure Communication Services now enables you to send and receive WhatsApp messages using the Advanced Messaging SDK. Get started with setting up Event Grid events for receiving WhatsApp messages send/receive status reports. Completing this quickstart incurs a small cost of a few USD cents or less in your Azure account.

Prerequisites

About Event Grid

Event Grid is a cloud-based eventing service. In this article, you learn how to subscribe to communication service events, and trigger an event to view the result. Typically, you send events to an endpoint that processes the event data and takes actions. In this article, we send the events to a web app that collects and displays the messages.

Set up Event Grid Viewer

The Event Grid Viewer is a sample site that allows you to view incoming events from Event Grid.

  1. Go to this Link Azure Event Grid Viewer - Code Samples | Microsoft Learn. Deploy the Event Grid Viewer sample by clicking Deploy to Azure.

  2. After clicking the Deploy to Azure, fill in the required fields. Because the site name creates a DNS entry, it needs to be globally unique. We recommended that you include your alias in the name for this step. While this quickstart doesn't require any special setup for this step, here are suggestions for filling out the deployment details:

  • Subscription - Select the subscription that contains your Azure Communication Services resource. This specific subscription isn't required, but it will make it easier to clean up after you're done with the quickstart.

  • Resource Group - Select the resource group that contains your Azure Communication Services resource. This specific resource group isn't required, but it will make it easier to clean up after you're done with the quickstart.

  • Region - Select the resource group that contains your Azure Communication Services resource. This specific region isn't required, but is recommended.

  • 'Site Name' - Create a name that is globally unique. This site name is used to create a domain to connect to your Event Grid Viewer.

  • 'Hosting Plan Name' - Create any name to identify your hosting plan.

  • 'Sku' - The sku F1 can be used for development and testing purposes. If you encounter validation errors creating your Event Grid Viewer that say there's no more capacity for the F1 plan, try selecting a different region. For more information about skus, see App Service pricing
