In this article, you learn how to use Azure Functions to create a "hello world" HTTP trigger function in the Azure portal.

A function app lets you group functions as a logical unit for easier management, deployment, scaling, and sharing of resources. Use these steps to create your function app and related Azure resources, whether or not you're able to edit your code in the Azure portal. ::: zone pivot="programming-language-csharp" To be able to create a C# script app that you can edit in the portal, choose **8 (LTS), in-process model** for .NET **Version**. ::: zone-end [!INCLUDE [Create function app Azure portal](../../includes/functions-create-function-app-portal.md)] Next, create a function in the new function app. ::: zone pivot="programming-language-python,programming-language-javascript,programming-language-powershell,programming-language-csharp" ## <a name="create-function"></a>Create an HTTP trigger function 1. In your function app, select **Overview**, and then select **+ Create** under **Functions**. If you don't see the **+ Create** button, you must instead [create your functions locally](./functions-develop-local.md). 1. Under **Select a template**, scroll down and choose the **HTTP trigger** template. 1. In **Template details**, use `HttpExample` for **New Function**, select **Anonymous** from the **[Authorization level](functions-bindings-http-webhook-trigger.md#http-auth)** drop-down list, and then select **Create**. Azure creates the HTTP trigger function. Now, you can run the new function by sending an HTTP request. ::: zone-end ::: zone pivot="programming-language-java,programming-language-csharp,programming-language-typescript,programming-language-python" ## Create your functions locally If you aren't able to create your function code in the portal, you can instead create a local project and publish the function code to your new function app. 1. In your function app, select **Overview**, and then in **Create functions in your preferred environment** under **Functions**. 1. Choose your preferred local development environment and follow the steps in the linked article to create and publish your first Azure Functions project. >[!TIP] >When publishing your new project, make sure to use the function app and related resources you just created. ::: zone-end ## Test the function [!INCLUDE [functions-test-function-portal](../../includes/functions-test-function-portal.md)] ## Clean up resources [!INCLUDE [Clean-up resources](../../includes/functions-quickstart-cleanup.md)] ## Next steps [!INCLUDE [Next steps note](../../includes/functions-quickstart-next-steps.md)]
