Common mistakes & gotchas
- Parameters are declared at the flow/solution level, not created inline in the designer like variables — referencing an undefined parameter name throws at save time.
- In solution-aware cloud flows, parameters are the standard way to keep environment-specific values (base URLs, thresholds) out of hardcoded expressions so a flow moves cleanly between dev/test/prod.
