n8n-flow-manager 0.1.0

A robust SDK and CLI for n8n workflow automation with DevOps capabilities

n8n-flow-manager 🚀

n8n-flow-manager is a robust, production-ready Python SDK and CLI for the n8n automation platform. Unlike simple HTTP wrappers, this package is designed for DevOps workflows, providing type-safe models, async operations, workflow templating, and CI/CD integration capabilities.

✨ Features

Core Capabilities

• ⚡ Async-First Design: Built on httpx for high-performance async operations
• 🛡️ Type Safety: Complete Pydantic models for workflows, executions, and credentials
• 🔄 Smart Polling: Execute workflows and wait for completion with intelligent status checking
• 📝 Jinja2 Templating: Inject environment-specific variables into workflow definitions
• 🤖 Powerful CLI: Terminal commands for backup, deploy, sync, and manage workflows
• 🔐 Secure: API key authentication with proper error handling and retries
• 📦 Zero Config: Works with environment variables or explicit configuration

What Makes It Different?

Feature	n8n-flow-manager	Generic HTTP Clients
Type Validation	✅ Pydantic models	❌ Raw dicts
Async Support	✅ Native asyncio	⚠️ Sync only
Smart Execution	✅ run_and_wait()	❌ Manual polling
Templating	✅ Jinja2 built-in	❌ Not included
CLI Tools	✅ Full featured	❌ None
Error Handling	✅ Custom exceptions	⚠️ Generic errors

🚀 Installation

Requirements

• Python 3.9 or higher
• n8n instance (cloud or self-hosted)

Install from PyPI

# Install with pip
pip install n8n-flow-manager

# Install with poetry
poetry add n8n-flow-manager

# Install CLI globally with pipx
pipx install n8n-flow-manager

Install from Source

# Clone the repository
git clone https://github.com/mgobea/n8n-flow-manager.git
cd n8n-flow-manager

# Install with Poetry (recommended)
poetry install --with dev

Install CLI Globally (Use n8n-py anywhere)

# Create wrapper script
mkdir -p ~/.local/bin
cat > ~/.local/bin/n8n-py << 'EOF'
#!/bin/bash
cd /path/to/n8n-flow-manager
poetry run n8n-py "$@"
EOF
chmod +x ~/.local/bin/n8n-py

# Add to PATH (if not already)
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc

Configuration

Create a .env file in your project root:

N8N_API_KEY=your_api_key_here

Or export as environment variables:

export N8N_API_KEY="your_api_key_here"
export N8N_BASE_URL="https://n8n.example.com"

Getting Your API Key

1. Open your n8n instance
2. Go to Settings → API
3. Generate a new API key
4. Copy and save it securely

🛠️ Usage Guide

1. Python SDK Usage

Basic Client Usage

import asyncio
from n8n_manager import N8NClient

async def main():
    # Initialize client (reads from environment)
    async with N8NClient() as client:

        # List all active workflows
        workflows = await client.workflows.list(active=True)
        for wf in workflows:
            print(f"Workflow: {wf.name} (ID: {wf.id})")

        # Get specific workflow
        workflow = await client.workflows.get("workflow_id")
        print(f"Nodes: {len(workflow.nodes)}")

        # Execute workflow and wait for result
        execution = await client.executions.run_and_wait(
            workflow_id="workflow_id",
            timeout=60
        )
        print(f"Status: {execution.status}")
        print(f"Success: {execution.is_successful}")

asyncio.run(main())

Creating Workflows Programmatically

from n8n_manager import N8NClient
from n8n_manager.models.workflow import Workflow, Node

async def create_simple_workflow():
    async with N8NClient() as client:
        workflow = Workflow(
            name="Python-Created Workflow",
            active=False,
            nodes=[
                Node(
                    name="Start",
                    type="n8n-nodes-base.start",
                    position=[250, 300],
                    parameters={}
                ),
                Node(
                    name="Set Data",
                    type="n8n-nodes-base.set",
                    position=[450, 300],
                    parameters={
                        "values": {
                            "string": [
                                {"name": "message", "value": "Hello from Python!"}
                            ]
                        }
                    }
                )
            ],
            connections={
                "Start": {
                    "main": [[{"node": "Set Data", "type": "main", "index": 0}]]
                }
            }
        )

        created = await client.workflows.create(workflow)
        print(f"Created workflow: {created.id}")

Using Templates

from n8n_manager.utils.templating import load_workflow_from_file

# Load workflow with template variables
workflow = load_workflow_from_file(
    "templates/data_sync.json",
    variables={
        "environment": "production",
        "api_endpoint": "https://api.example.com",
        "timeout": 30
    }
)

async with N8NClient() as client:
    deployed = await client.workflows.create(workflow)
    print(f"Deployed: {deployed.name}")

2. CLI Usage

The CLI provides powerful commands for workflow management.

$ n8n-py health
✓ Connection healthy!
  API URL: https://n8n.example.com/
