Business Rule Validation

This task works as a simple business rule that you build and apply several times while designing a mobile app in the vDesigner application. Business rules are applied to satisfy a condition. Business rules are used in multiple scenarios such as data validation, authentication, sending OTP and user credentials, and others. If the condition of the business rule satisfies as a result user-action, the mobile app either performs the next step or execution halts.

Whether the application will perform the next step or stop depends on the condition that you define in the business rule.
