About Maestro Flow

Nota:

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.

Tipos de nodos

Nodes are organized into categories in the Add node panel:

Categoría	Descripción
Agente	UiPath agents and external AI agents
Proceso de agente	Invoke a Maestro BPMN process
Flujo de trabajo de API	Call an API workflow
Conector	Integration Service connector actions
Control	Branching, looping, and flow control nodes
Flujo	Invoke another Flow as a subflow
Human task	Human approvals and action apps
RPA workflow	Invoke an RPA workflow
Herramienta	Data transformation and scripting nodes
Document processing	Summarize or extract data from documents

Agente

When you select Agent, the following options appear:

Nodo	Descripción
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

Control

When you select Control, the following options appear:

Nodo	Descripción
Mock	Placeholder node for prototyping — does nothing at runtime
Decisión	Branches to a true or false path based on a JavaScript expression
Bucle	Iterates over a collection, executing its body once per item
Fusionar	Joins parallel branches back into a single path
Interruptor	Routes to one of several branches based on an ordered list of conditions
Retraso	Pauses execution for a specified duration or until a target date
Subflow	Groups a set of nodes into a reusable, self-contained unit
Finalizar	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:

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

Herramienta

When you select Tool, the following options appear:

Nodo	Descripción
Solicitud HTTP	Calls any REST API endpoint and returns the response
Script	Runs custom JavaScript code
Transformación por lotes	Adds AI-generated columns to a CSV
Transformar	Reshapes and converts data
Filtro	Filters data by conditions
Mapa	Renames and transforms fields
Group By	Groups data by a field with aggregation
Crear elemento de la cola	Adds an item to an Orchestrator queue
Crear y esperar el artículo en cola	Adds a queue item and waits for it to complete

Document processing

When you select Document processing, the following options appear:

Nodo	Descripción
Resumir	Creates a complex summary of a document
Extraer	Extracts structured data using an IXP model deployed to a folder in your tenant
