They are separate features. Workflow Builder is for automated journeys (triggers, messages, collect input, conditions, API, agent transfer). WhatsApp Flows (wa_flow) is for building multi-screen forms (screens, components, Flow JSON for Meta). Use Workflow Builder for conversation flows and automation; use WhatsApp Flows when you need native Flow forms (e.g. checkout, registration) inside WhatsApp. Both are under the WhatsApp module with different entry points.
