About Maestro Flow

注:

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.

ノードの種類

Nodes are organized into categories in the Add node panel:

カテゴリ (Category)	説明
オペレーター	UiPath agents and external AI agents
エージェンティック プロセス	Invoke a Maestro BPMN process
API ワークフロー	Call an API workflow
コネクタ	Integration Service connector actions
制御	Branching, looping, and flow control nodes
フロー	Invoke another Flow as a subflow
Human task	Human approvals and action apps
RPA workflow	Invoke an RPA workflow
ツール	Data transformation and scripting nodes
Document processing	Summarize or extract data from documents

オペレーター

When you select Agent, the following options appear:

ノード	説明
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

制御

When you select Control, the following options appear:

ノード	説明
Mock	Placeholder node for prototyping — does nothing at runtime
判断	Branches to a true or false path based on a JavaScript expression
ループ	Iterates over a collection, executing its body once per item
結合	Joins parallel branches back into a single path
条件分岐 (switch)	Routes to one of several branches based on an ordered list of conditions
待機	Pauses execution for a specified duration or until a target date
Subflow	Groups a set of nodes into a reusable, self-contained unit
末尾	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:

ノード	説明
Quick Form	Fast inline approvals with inline debug support
Action App	A customized coded action app service

ツール

When you select Tool, the following options appear:

ノード	説明
HTTP 要求	Calls any REST API endpoint and returns the response
スクリプト	Runs custom JavaScript code
バッチ変換	Adds AI-generated columns to a CSV
変換	Reshapes and converts data
フィルター	Filters data by conditions
Map	Renames and transforms fields
Group By	Groups data by a field with aggregation
キュー アイテムを作成	Adds an item to an Orchestrator queue
キュー アイテムを作成して待機	Adds a queue item and waits for it to complete

Document processing

When you select Document processing, the following options appear:

ノード	説明
要約	Creates a complex summary of a document
抽出	Extracts structured data using an IXP model deployed to a folder in your tenant
