The webMethods API-Portal solution consists of CentraSite, webMethods Mediator, and webMethods API-Portal. At a minimum, CentraSite is required to publish APIs to the API-Portal. Ensure you have a CentraSite instance installed before configuring API-Portal. webMethods Mediator is optional.

If you are using Enterprise Gateway to secure traffic between API consumer requests and the execution of services on Mediator, ensure that CentraSite, Integration Server, and Mediator are installed behind the firewall. In this scenario, the Enterprise Gateway Server is installed in the DMZ for external access. Alternatively, for internal users only, you can use Integration Server with Mediator deployed in a secure network behind the firewall.
