RPA Node Types

RPA workflows are built from explicit node types with deterministic success checks.

Core control flow nodes

• start: defines workflow entry
• if: conditional branch on evaluated state
• loop: iterate rows or repeated actions
• wait: explicit synchronization on UI state

UI interaction nodes

• navigate: open target URL
• click: activate a UI element
• type: enter text into an input
• select: choose value from dropdown controls

Data and assertion nodes

• extract: capture field content for outputs
• assert: validate expected value/state before continuing
• screenshot: capture evidence for audit or debugging

Design guidelines

• Prefer explicit assertions before irreversible actions.
• Keep node intent single-purpose and testable.
• Include fallback paths for known stop conditions.
• Avoid hidden state mutations inside generic script blobs.

Production checks

Before releasing a workflow revision:

• Validate selectors in a clean environment.
• Run canary batch.
• Confirm terminal states and error taxonomy are stable.
