Which scenario best illustrates when to use a shared private parameter in a self-serve workflow?

• A. You want the user to be able to choose the directory to write their data.
• B. You need the user to provide their own API key before running the workspace.
• C. You have multiple transformers with a Tolerance parameter, and you want them to use the same value and you don't want the end-user to set that value.
• D. You want the user to be able to choose the directory to write read data.

Answer: (C)

In a self-serve workflow, a shared private parameter is used to centralize a value that multiple components should use, while keeping that value hidden from the end user. This ensures consistency across all parts of the workflow and prevents users from changing it accidentally. The scenario with several transformers that all rely on a Tolerance value, and where you don’t want the end user to set that value, is exactly when a shared private parameter shines: you define the value once and have every transformer reference it, preserving uniform behavior. The other situations involve user-configurable inputs (like choosing directories) or user-provided secrets (like an API key), which are not suited to a private, shared parameter intended for centralized control.
