In the API Settings section for a specific API, the end point of the API on the API Gateway is displayed. This is the endpoint you will use in your application (see also your applications) to speak to the API with.
See also the API Index Help Page for a discussion on the different ways of accessing a secured API, using API Keys or the OAuth 2.0 Client Credentials Flow.
Click on the "Description" headline to display a description of the API. This section also contains a link to the "Swagger" documentation of the end points of the specific API. If you use this button (and not the "Try it" buttons described below), you will retrieve a read only documentation of the API, in Swagger UI. Swagger UI is also able to let you actually interact with the API, but that requires a subscription.
The "Applications" section contains all your registered applications (see also application help page), and their relation to the current API. In case you have existing subscriptions, you will be able to display the credentials for this API. In case you don't have a subscription for the API for a specific application, you may add a subscription by clicking the Subscribe button.
