Which context variable allows access to any property in scope plus the {{payload}} variable?

• A. Attributes {{attrs}}
• B. Page parameters {{params}}
• C. Session variables {{session}}
• D. Object {{objj}}

Answer: (B)

The correct response is based on the understanding of context variables in the Vlocity Platform and their respective functions. The context variable that allows access to any property in scope, including the {{payload}} variable, is indeed the page parameters.

Page parameters are designed to hold contextual information that can vary based on the interaction within the application. This means that, while the other context variables might give access to specific types of data, page parameters are particularly useful because they encompass broader access, including properties from the payload. This allows developers to build dynamic and responsive applications that can adjust based on user input and interactions.

The other context variables serve more specialized purposes. For instance, attributes are typically used to track specific data related to UI components. Session variables hold information relevant to a user’s session but do not necessarily bridge that information with the {{payload}} context in the same flexible manner as page parameters. The object variable is usually focused on a single record's data, which limits accessibility compared to page parameters that can encompass multiple values and contexts.
