What object is automatically created when you use the Call Web Service Smart Service?

When the Call Web Service Smart Service is utilized, a Characteristic Data Type (CDT) is automatically created to represent the structure of the data being exchanged with the external web service. This is essential because the CDT defines the schema of the data, which allows Appian to map and transform data between the web service and your application seamlessly.

A CDT is a powerful feature in Appian, as it provides a structured way to define custom data models that correspond to the data formats expected by the web service you are integrating. By generating this CDT automatically, Appian enhances the developer's efficiency, allowing them to focus on other critical aspects of the integration without needing to manually define the data structure.

Considering the other options, while a process model and smart service instance are integral parts of the Appian workflow and execute calls to web services, they are not automatically created as a direct result of executing the Call Web Service Smart Service. Similarly, a web service connector is a tool used to facilitate communication with external services but does not itself represent the data structure being exchanged. Thus, the creation of the CDT stands out as the primary result of invoking the Call Web Service Smart Service.
