 When you enable this option, App Service adds a webhook to your repository in Azure Container Registry or Docker Hub. Your repository posts to this webhook whenever your selected image is updated with `docker push`. The webhook causes your App Service app to restart and run `docker pull` to get the updated image.

+> To ensure the proper functioning of the webhook, it's essential to enable the **Basic Auth Publishing Credentials** option within your Web App. Failure to do so may result in a 401 unauthorized error for the webhook.
+>To verify whether **Basic Auth Publishing Credentials** is enabled, follow these steps:
+> 
+> - Navigate to your Web App's **Configuration > General Settings**.
+> - Look for the **Platform Setting** section, where you will find the **Basic Auth Publishing Credentials** option.

 **For other private registries**, your can post to the webhook manually or as a step in a CI/CD pipeline. In **Webhook URL**, **click** the **Copy** button to get the webhook URL.
