Services are shown as unknown in the API Catalogue if they are missing technical service descriptions from the Security Server WebUI. Without a service description, API Catalogue cannot recognise whether the service is a REST or SOAP service.
Usually, an unknown service is a REST service that has been added to the Data Exchange Layer using the REST API Base Path. API Catalogue cannot recognise these types of services as REST services. The technical description for a REST service has to be in OpenAPI 3 format for it to show automatically in the API Catalogue.
We recommend adding REST services to the Data Exchange Layer by using OpenAPI 3 Description path in the Security Server WebUI. This way the API Catalogue can recognise the service and show the technical interface description automatically. Even if you cannot add the technical description in OpenAPI 3 format, we still recommend adding a description, for example as an attachment.
Sometimes, SOAP service’s WSDL-description can disappear. In this case, the service also shows as unknown in the API Catalogue.
