UiPath LangChain Python SDK
A Python SDK that enables developers to build and deploy LangGraph agents to the UiPath Platform. This package provides programmatic interaction with UiPath Platform services and human-in-the-loop (HITL) semantics through Action Center integration.
This package is an extension to the UiPath Python SDK.
Requirements
- Python 3.10 or higher
- UiPath Automation Cloud account
Installation
using uv:
Configuration
Environment Variables
Create a .env file in your project root with the following variables:
Command Line Interface (CLI)
The SDK provides a command-line interface for creating, packaging, and deploying LangGraph Agents:
Initialize a Project
Creates a uipath.json configuration file for your project. If [GRAPH] is omitted, it will create an entrypoint for each graph specified in the langgraph.json file.
Authentication
This command opens a browser for authentication and creates/updates your .env file with the proper credentials.
Debug a Project
Executes the agent with the provided JSON input arguments.
Package a Project
Packages your project into a .nupkg file that can be deployed to UiPath.
Note: Your pyproject.toml must include:
- A description field (avoid characters: &, <, >, ", ', ;)
- Author information
Example:
description = "Your package description"
authors = [{name = "Your Name", email = "your.email@example.com"}]
Publish a Package
Publishes the most recently created package to your UiPath Orchestrator.
Project Structure
To properly use the CLI for packaging and publishing, your project should include:
- A pyproject.toml file with project metadata
- A langgraph.json file
- A uipath.json file (generated by uipath init)
- Any Python files needed for your automation
