Publishing Managed Gateway and Connected Mode APIs
For Managed Flex Gateway or Flex Gateway running in Connected Mode, use API Manager to publish both API instances with a single upstream service and API instances with multiple upstream services.
For more information, see Adding a Flex Gateway API Instance.
Additionally, you can publish a simple API with Getting Started with Managed Flex Gateway on CloudHub 2.0 or Getting Started with Self-Managed Flex Gateway in Connected Mode.
