Workflows - Docs2work

A workflow is a directed graph of nodes and edges. It defines what happens, in what order, with what data, and who or what is responsible at each step.

Node types

type	Purpose
`form`	Intake or review form step
`approval`	Human approve/reject
`validation`	Human validate/reject
`signature`	Human signs
`conditional`	Branch on context value
`split`	Parallel execution
`pause`	Wait step
`send_message`	Email and/or WhatsApp
`create_sheet_row`	Create sheet row
`update_sheet_row`	Update sheet row
`ai_classify`	Classify text
`ai_extract`	Extract structured fields
`ai_summarize`	Summarize text
`ai_intent`	Detect intent
`ai_transform`	Free-form AI output
`parse_document`	Parse PDF or image
`end`	Terminal node

The audit trail

Every node execution is logged in workflow_run_events with the actor type (human or agent), the actor identifier, the node ID, and the full input and output context. This is what lets you answer “what happened and why” weeks after a process ran.
