[!INCLUDE [functions-in-portal-editing-note](../../includes/functions-in-portal-editing-note.md)] ## Prerequisites - An Azure subscription. If you don't have one, create a [free account](https://azure.microsoft.com/pricing/purchase-options/azure-account?cid=msft_learn) before you begin. ## Create an Azure Function app [!INCLUDE [Create function app Azure portal](../../includes/functions-create-function-app-portal.md)] Next, you create a function in the new function app. <a name="create-function"></a> ## Create a Queue triggered function 1. In your function app, select **Overview**, and then select **+ Create** under **Functions**. 1. Under **Select a template**, scroll down and choose the **Azure Queue Storage trigger** template. 1. In **Template details**, configure the new trigger with the settings as specified in this table, then select **Create**: | Setting | Suggested value | Description | |---|---|---| | **Job type** | Append to app | You only see this setting for a Python v2 app. | | **Name** | Unique in your function app | Name of this queue triggered function. | | **Queue name** | myqueue-items | Name of the queue to connect to in your Storage account. | | **Storage account connection** | AzureWebJobsStorage | You can use the storage account connection already being used by your function app, or create a new one. | Azure creates the Queue Storage triggered function based on the provided values. Next, you connect to your Azure storage account and create the **myqueue-items** storage queue. ## Create the queue 1. Return to the **Overview** page for your function app, select your **Resource group**, then find and select the storage account in your resource group. 1. In the storage account page, select **Data storage** > **Queues** > **+ Queue**. 1. In the **Name** field, type `myqueue-items`, and then select **Create**. 1. Select the new **myqueue-items** queue, which you use to test the function by adding a message to the queue. ## Test the function 1. In a new browser window, return to your function app page and select **Log stream**, which displays real-time logging for your app. 1. In the **myqueue-items** queue, select **Add message**, type "Hello World!" in **Message text**, and select **OK**. 1. Go back to your function app logs and verify that the function ran to process the message from the queue. 1. Back in your storage queue, select **Refresh** and verify that the message has been processed and is no longer in the queue. ## Clean up resources [!INCLUDE [Next steps note](../../includes/functions-quickstart-cleanup.md)] ## Next steps You have created a function that runs when a message is added to a storage queue. For more information about Queue storage triggers, see [Azure Functions Storage queue bindings](functions-bindings-storage-queue.md). Now that you have a created your first function, let's add an output binding to the function that writes a message back to another queue. > [!div class="nextstepaction"] > [Add messages to an Azure Storage queue using Functions](functions-integrate-storage-queue-output-binding.md)
