API Development & Integration Flashcards

In Informatica Cloud, which HTTP status code should an API return when a requested resource cannot be found?

Answer: 404 Not Found

HTTP 404 Not Found is the standard response when the server cannot locate the requested resource.

What is the purpose of configuring 'Connection Timeout' and 'Read Timeout' in an IICS REST V2 connection?

Answer: To control how long the connector waits when establishing a connection and when waiting for a response

Connection Timeout and Read Timeout prevent a mapping from hanging indefinitely by capping how long it waits for TCP connection establishment and server response respectively.

In IICS Application Integration, what is a 'Guide' (formerly 'Human Task') primarily used for?

Answer: Pausing a process to collect input or approval from a human user before continuing

A Guide introduces a human interaction step in a process, pausing execution until a user reviews and submits a form response.

When an IICS published API needs to enforce that consumers include a unique key in every request header, which policy type provides this control?

Answer: API Key Authentication Policy

An API Key Authentication Policy requires consumers to pass a valid API key in the request header before the API will process the call.

In IICS, when a REST source returns nested JSON objects, which transformation is most useful for flattening the hierarchy into rows?

Answer: Normalizer Transformation

The Normalizer transformation flattens nested or repeating groups from hierarchical data (like JSON arrays) into individual rows.

Which IICS feature enables you to test an API endpoint directly within the Application Integration design canvas before publishing?

Answer: Test Run / Debug mode

The Test Run (Debug) mode in the Application Integration designer lets you execute a process and inspect variable values and step outputs without publishing.

When sending a large payload to an external REST API in IICS, which approach best addresses API payload size limits?

Answer: Splitting the data into batches and making multiple API calls within the mapping

Batching the data and iterating over multiple API calls is the standard pattern to handle APIs that enforce payload size limits.
