API-First Strategy

BC.

An API-First strategy is an approach to software development where the API definition or contract is created before implementing any business logic or building any UI components. This approach allows multiple teams to work in parallel, with backend developers working on the API while front-end developers work on the user interface.

Option A is incorrect because an API-First strategy is not specific to SOAP/WSDL. While SOAP/WSDL can be used to define APIs, there are other specifications such as RESTful APIs that can also be used.

Option B is correct because the API definition is created first, allowing teams to work in parallel. This approach also helps to ensure that the API is well-designed and meets the needs of its users before any work is done on its implementation.

Option C is also correct because the API is developed before any UI or new business logic is created. This approach ensures that the API is the foundation of the system and that any new features or changes are built on top of the API, rather than being tightly coupled to the UI or business logic.

Option D is incorrect because the code to execute business logic does not need to exist before creating an API-First strategy. In fact, the API definition can be created before any code is written, allowing for a more flexible and iterative approach to software development.

In summary, an API-First strategy involves creating the API definition or contract first, before implementing any business logic or building any UI components. This approach allows multiple teams to work in parallel and helps to ensure that the API is well-designed and meets the needs of its users.
