The Swagger UI
Using the Swagger UI, you can visualize and test RESTful services defined by the Swagger specification. It specifies the format (URL, method, and representation) to describe the REST web services.
Viewing Multiple REST Services in Swagger UI
If there are multiple REST services using different HTTP Connectors, you can select a single HTTP Connector to receive responses for all the REST services. From the Swagger UI, select the connector from the options in the drop down list for Select HTTP Connector.
At runtime, the Swagger UI lists all the REST services that are using the selected HTTP Connector.
