IICS Certification API Management in IICS 3

Question 1

What is 'request transformation' in IICS API Center?

Accepted Answer

Modifying or mapping the incoming API request payload before it reaches the backend process

Answer

Request transformation allows the API gateway to modify, map, or enrich the incoming request payload before passing it to the backend integration process.

Question 2

In IICS API Center, what does 'response caching' accomplish?

Accepted Answer

Storing API responses temporarily to serve repeat identical requests without hitting the backend, improving performance

Answer

Response caching stores API responses for a configured duration so that repeat requests can be served from cache without invoking the backend process again.

Question 3

What is the purpose of 'API subscription plans' in IICS API Center?

Accepted Answer

Defining different tiers of access with varying rate limits, quotas, and features for different consumer categories

Answer

Subscription plans let API providers offer different access tiers — for example, basic vs. premium — each with different rate limits and allowed features.

Question 4

In IICS, how does the API gateway handle an API request when the backend Application Integration process is unavailable?

Accepted Answer

The gateway returns an appropriate HTTP error (e.g., 503 Service Unavailable) and logs the failure

Answer

When the backend is unavailable, the API gateway returns an appropriate HTTP error response (such as 503) and records the failure for monitoring.

Question 5

What is 'API mocking' in the context of IICS API Center development?

Accepted Answer

Simulating an API's responses without a real backend, enabling consumers to develop against it before the implementation is ready

Answer

API mocking returns simulated responses based on the API definition, allowing consumer teams to start development before the backend integration is complete.
