Workflow and Node

2. Workflow and Node Concepts

2.1. Workflow

A workflow is a process flow represented as a diagram. A workflow usually starts with a trigger event and goes through multiple processing steps to produce a final result.

2.2. Node

A node is a functional block in a workflow, representing one processing step. Each node can:

• Receive input from a previous node or from a trigger.
• Execute an action.
• Return output to the next node.

A typical workflow includes these common node groups:

• Trigger node: Starts a workflow (schedule-based, event-based, user-request-based, etc.).
• Action node: Process data, call APIs, create documents, send notifications, update systems, etc.
• Logic node: Conditional branching, loops, merge/split flows, error checks, etc.
• AI node: Extract information, summarize, classify, analyze content, suggest conclusions, etc.
• Output/Storage node: Store results, write logs, push data to other systems, etc.
