langchain-notion

This package provides a LangChain integration for interacting with Notion via the LangchainNotion toolkit and tools. It enables you to access, search, create, and update Notion pages programmatically using LangChain interfaces.

Installation

pip install -U langchain-notion

Configuration

Set your Notion API key as an environment variable before using the toolkit:

export NOTION_API_KEY="your-notion-api-key"

Usage: Notion Toolkit & Tools

The toolkit provides tools for interacting with Notion pages:

import os
from langchain_notion.toolkits import LangchainNotionToolkit
from langchain_notion.notion_wrapper import NotionWrapper

key = os.environ.get("NOTION_API_KEY")
api = NotionWrapper(api_key=key)
toolkit = LangchainNotionToolkit.from_notion_wrapper(api, include_write_tools=True)
tools = toolkit.get_tools()

# Example: Search for pages
tool = next(t for t in tools if t.name == "Search Pages")
print(tool.invoke({"tool_input": "test"}))

Project Structure & Maintenance
