 When you run your app on an App Service plan, you should enable the **Always on** setting so that your function app runs correctly. On an App Service plan, the Functions runtime goes idle after a few minutes of inactivity. The **Always on** setting is available only on an App Service plan. In other plans, the platform activates function apps automatically. If you choose not to enable **Always on**, you can reactivate an idled app in these ways:
 
-+ Send a request to an HTTP trigger endpoint.
-+ Send a request to an `/admin` API endpoint (requires the [master key](function-keys-how-to.md#understand-keys)).
++ Send a request to an HTTP trigger endpoint or any other endpoint on the app. Even a failed request should wake up your app. 
 + Acccess your app in the [Azure portal](https://portal.azure.com). 
 
 Even with **Always on** enabled, the execution timeout for individual functions is controlled by the `functionTimeout` setting in the [host.json](functions-host-json.md#functiontimeout) project file.
