Sample text

An advantage of this approach is the homogeneous API portfolio and homogeneous security and access control from the perspective of the API consumer. As a result, the same security and access control applies to all APIs, whether the APIs are internal or external. There may be legal restrictions for re-exposing third party APIs. To find out whether it is allowed to reuse third party APIs, check their terms of service. Customization A successful API portfolio addresses and satisfies the needs of the API consumers.

Removing fields from the request or response (as opposed to making it optional). Changing a previously optional request field in the body or parameter into a mandatory field. Changing a previously required response field in the body or parameter into an optional field. Changing the URI of the API, such as host name, port or path. g. making an existing field a child of some other field. Adding a new mandatory field to the data structure. Reasons for breaking changes can be changed validation rules, new APIproducts, new database, new infrastructure, consumers using the API in new way.

2. Create an implementation to mediate between the interface and the backend system. The implementation enforces security, authorizes consumers, monitors usage, and shapes the traffic. Almost all APIs apply the facade pattern, especially when APIs are used to provide access to legacy systems. An exception may be APIs without any dependencies to legacy systems. They can be found in startups and young companies. In these cases, the API does not require the facade pattern, since the business logic is implemented as part of the API.
