 - **Managed version** - by editing and customizing the portal, which is built into your API Management instance and is accessible through the URL `<your-api-management-instance-name>.developer.azure-api.net`. Refer to [this documentation article](api-management-howto-developer-portal-customize.md) to learn how to access and customize the managed portal.
