Chapter 3. Agile integration: Capability perspectives  47 Figure 3-5 Differentiating exposure from implementation in API-led integration The API management capability enables API providers to create or import an interface  specification, provide the necessary configuration for a security model, and document how to  use it. The API provider can then decide who should be able to see and subscribe to the API  and what service they can expect, for example, in terms of throughput rate. At the designer’s  request, the API management capability then simultaneously configures the API gateway,  makes the documentation available through a portal site, provides facilities for  self-subscription to the API, and collects data on the usage.
