Which Appian object is used to model an external system integration with Appian?

• A. Web API
• B. Integration Object
• C. Connected System Object
• D. Initiate Call Smart Service

Answer: (B)

In Appian, modeling an external system integration is done with an Integration Object. It defines the operations you call, the structure of the request and response, and how data is mapped between Appian and the external service. It typically relies on a Connected System for the actual connection details like the endpoint and authentication. The other options serve different roles: a Web API is for exposing Appian functionality to external callers, not for modeling an external integration; a Connected System Object holds connection settings but doesn’t define the specific integration operations; and an Initiate Call Smart Service is not the mechanism used to model an integration. So, the Integration Object is the correct choice.
