When is a list of dictionary typically created in Appian?

A list of dictionaries in Appian is typically created when data is returned from an integration. Integrations often involve connecting Appian applications to external systems through APIs or web services. When the external system returns data in a structured format, such as JSON or XML, Appian converts this data into a list of dictionaries for easier manipulation and use within the application.

This conversion allows developers to work with the data in a more manageable way, where each dictionary represents a record or object, containing key-value pairs that correspond to the properties of the returned data. This structure is essential for processing and displaying the information within Appian interfaces, ensuring that users can interact with the data seamlessly.

In the context of other options, while lists of dictionaries can be generated from database queries or created manually, the scenario specifically highlights integration returns as a common use case for their creation, making it a pivotal aspect of data handling in Appian applications.
