API Development & Integration Flashcards

In IICS, what is the significance of the 'Base URL' field when configuring an API Group?

Answer: It defines the common URL prefix shared by all APIs published under that group

The Base URL is the common path prefix prepended to each individual API's relative URL within a group, forming the full endpoint address.

An IICS REST API integration must handle the scenario where the external API returns a 429 'Too Many Requests' response. What is the recommended handling approach?

Answer: Implement retry logic with exponential backoff to respect the API rate limit

Exponential backoff retry logic respects the external API's rate limits by progressively increasing wait time between retries after a 429 response.

In Informatica Cloud Application Integration, what does 'publishing' an API process make available?

Answer: It exposes the process as a live, callable REST or SOAP endpoint accessible to consumers

Publishing an API process in Application Integration activates its API trigger, making it reachable at its configured endpoint URL.

Which field in the IICS REST V2 target transformation determines how the HTTP method (POST, PUT, PATCH, DELETE) is applied per request?

Answer: Operation Type

The Operation Type field in the REST V2 target transformation specifies which HTTP verb (Insert=POST, Update=PUT/PATCH, Delete=DELETE) to use for each record.

When integrating with a SOAP web service in IICS, which transformation is used to invoke the web service operation?

Answer: Web Service Consumer Transformation

The Web Service Consumer Transformation in IICS mappings is designed to invoke SOAP web service operations using a configured WSDL-based connection.

In IICS, what is the function of the 'Response Schema' on a published API process?

Answer: It defines the structure and data types of the payload the API returns to the caller

The Response Schema declares the expected output structure so consumers know how to parse the data returned by the API.

When using Informatica Cloud's API Microgateway in an on-premises deployment, what is its primary function?

Answer: Acting as the entry point for API traffic, enforcing policies before forwarding requests to Application Integration

The Microgateway is a lightweight proxy that intercepts incoming API calls, applies security and traffic policies, and then routes approved requests to the Application Integration runtime.
