About Maestro Flow

Hinweis:

Maestro Flow is in Preview.

Maestro Flow is a visual canvas for building and deploying automations that connect APIs, AI agents, human approvals, document processing, and enterprise services. You design a Maestro Flow by placing nodes on a canvas and connecting them, then debug and publish it directly from Studio Web.

Flow processes run on the UiPath Maestro runtime alongside RPA workflows, API workflows, and Maestro BPMN processes. If you have used Maestro BPMN before, Flow is a different modeler built on the same runtime — designed for developers who prefer a visual, node-based experience over BPMN notation.

Knotentypen

Nodes are organized into categories in the Add node panel:

Kategorie	Beschreibung
Mitarbeiter	UiPath agents and external AI agents
Agent-Prozess	Invoke a Maestro BPMN process
API-Workflow	Call an API workflow
Connector	Integration Service connector actions
Steuerung	Branching, looping, and flow control nodes
Flow	Invoke another Flow as a subflow
Human task	Human approvals and action apps
RPA workflow	Invoke an RPA workflow
Tool	Data transformation and scripting nodes
Document processing	Summarize or extract data from documents

Mitarbeiter

When you select Agent, the following options appear:

Knoten	Beschreibung
Autonomous Agent	A UiPath AI agent that completes tasks autonomously
External AI agents	Third-party AI agents — includes Databricks Agent, Google Vertex, Microsoft Azure AI Foundry, and Snowflake Cortex

Steuerung

When you select Control, the following options appear:

Knoten	Beschreibung
Mock	Placeholder node for prototyping — does nothing at runtime
Entscheidung	Branches to a true or false path based on a JavaScript expression
Schleife	Iterates over a collection, executing its body once per item
Zusammenführen	Joins parallel branches back into a single path
Umschalten (Switch)	Routes to one of several branches based on an ordered list of conditions
Verzögerung (Delay)	Pauses execution for a specified duration or until a target date
Subflow	Groups a set of nodes into a reusable, self-contained unit
Beenden	Marks the end of a workflow path
Terminate	Ends the flow immediately with a success or failure status

Human task

When you select Human task, the following options appear:

Knoten	Beschreibung
Quick Form	Fast inline approvals with inline debug support
Action App	A customized coded action app service

Tool

When you select Tool, the following options appear:

Knoten	Beschreibung
HTTP-Anfrage (HTTP Request)	Calls any REST API endpoint and returns the response
Skript	Runs custom JavaScript code
Batch-Transformation	Adds AI-generated columns to a CSV
Transformieren	Reshapes and converts data
Filter	Filters data by conditions
Karte	Renames and transforms fields
Group By	Groups data by a field with aggregation
Warteschlangenelement erstellen	Adds an item to an Orchestrator queue
Warteschlangenelement erstellen und warten	Adds a queue item and waits for it to complete

Document processing

When you select Document processing, the following options appear:

Knoten	Beschreibung
Zusammenfassen	Creates a complex summary of a document
Extrahieren	Extracts structured data using an IXP model deployed to a folder in your tenant
