notion-sdk-py is a simple and easy to use client library for the official Notion API.

It is meant to be a Python version of the reference JavaScript SDK, so usage should be pretty similar between both. 😊

📢 Announcement (10-12-2022) — Release 2.0.0 is out! It mostly adds new helpers, support for the comments API, more tests, and Python 3.11.

Beware, Notion-Version has been upgraded to 2022-06-28 and it brings breaking changes.

Installation

pip install notion-client

Usage

Before getting started, create an integration and find the token. → Learn more about authorization.

Import and initialize a client using an integration token or an OAuth access token.

import os
from notion_client import Client

notion = Client(auth=os.environ["NOTION_TOKEN"])

In an asyncio environment, use the asynchronous client instead:

from notion_client import AsyncClient

notion = AsyncClient(auth=os.environ["NOTION_TOKEN"])

Make a request to any Notion API endpoint.

See the complete list of endpoints in the API reference.

from pprint import pprint

list_users_response = notion.users.list()
pprint(list_users_response)

or with the asynchronous client:

list_users_response = await notion.users.list()
pprint(list_users_response)

This would output something like:

{'results': [{'avatar_url': 'https://secure.notion-static.com/e6a352a8-8381-44d0-a1dc-9ed80e62b53d.jpg',
              'id': 'd40e767c-d7af-4b18-a86d-55c61f1e39a4',
              'name': 'Avocado Lovelace',
              'object': 'user',
              'person': {'email': '[email protected]'},
              'type': 'person'},
             ...]}

All API endpoints are available in both the synchronous and asynchronous clients.

Endpoint parameters are grouped into a single object. You don't need to remember which parameters go in the path, query, or body.

my_page = notion.databases.query(
    **{
        "database_id": "897e5a76-ae52-4b48-9fdf-e71f5945d1af",
        "filter": {
            "property": "Landmark",
            "rich_text": {
                "contains": "Bridge",
            },
        },
    }
)

Handling errors

If the API returns an unsuccessful response, an APIResponseError will be raised.

The error contains properties from the response, and the most helpful is code. You can compare code to the values in the APIErrorCode object to avoid misspelling error codes.

import logging
from notion_client import APIErrorCode, APIResponseError

try:
    my_page = notion.databases.query(
        **{
            "database_id": "897e5a76-ae52-4b48-9fdf-e71f5945d1af",
            "filter": {
                "property": "Landmark",
                "rich_text": {
                    "contains": "Bridge",
                },
            },
        }
    )
except APIResponseError as error:
    if error.code == APIErrorCode.ObjectNotFound:
        ...  # For example: handle by asking the user to select a different database
    else:
        # Other error handling code
        logging.error(error)

Logging

The client emits useful information to a logger. By default, it only emits warnings and errors.

If you're debugging an application, and would like the client to log request & response bodies, set the log_level option to logging.DEBUG.

notion = Client(
    auth=os.environ["NOTION_TOKEN"],
    log_level=logging.DEBUG,
)

You may also set a custom logger to emit logs to a destination other than stdout. Have a look at Python's logging cookbook if you want to create your own logger.

Client options

Client and AsyncClient both support the following options on initialization. These options are all keys in the single constructor parameter.

Option	Default value	Type	Description
auth	None	string	Bearer token for authentication. If left undefined, the auth parameter should be set on each request.
log_level	logging.WARNING	int	Verbosity of logs the instance will produce. By default, logs are written to stdout.
timeout_ms	60_000	int	Number of milliseconds to wait before emitting a RequestTimeoutError
base_url	"https://api.notion.com"	string	The root URL for sending API requests. This can be changed to test with a mock server.
logger	Log to console	logging.Logger	A custom logger.

Full API responses

The following functions can distinguish between full and partial API responses.

Function	Purpose
is_full_page	Determine whether an object is a full Page object
is_full_block	Determine whether an object is a full Block object
is_full_database	Determine whether an object is a full Database object
is_full_user	Determine whether an object is a full User object
is_full_comment	Determine whether an object is a full Comment object

from notion_client.helpers import is_full_page

full_or_partial_pages = await notion.databases.query(
    database_id="897e5a76-ae52-4b48-9fdf-e71f5945d1af"
)

for page in full_or_partial_pages["results"]:
    if not is_full_page(page):
        continue
    print(f"Created at: {page['created_time']}")

Utility functions

These functions can be helpful for dealing with any of the paginated APIs.

iterate_paginated_api(function, **kwargs) and its async version async_iterate_paginated_api(function, **kwargs) turn any paginated API into a generator.

The function parameter must accept a start_cursor argument. Example: notion.blocks.children.list.

from notion_client.helpers import iterate_paginated_api

for block in iterate_paginated_api(
    notion.databases.query, database_id="897e5a76-ae52-4b48-9fdf-e71f5945d1af"
):
    # Do something with block.
    ...

If you don't need a generator, collect_paginated_api(function, **kwargs) and its async version async_collect_paginated_api(function, **kwargs) have the same behavior than the previous functions, but return a list of all results from the paginated API.

from notion_client.helpers import collect_paginated_api

all_results = collect_paginated_api(
    notion.databases.query, database_id="897e5a76-ae52-4b48-9fdf-e71f5945d1af"
)

Testing

Run the tests with the pytest command: the tests are using pytest-vcr's cassettes for simulating requests to the Notion API.

To create new tests or run them without cassettes, you need to set up the environment variables NOTION_TOKEN and NOTION_TEST_PAGE_ID (a page where your integration has all the capabilities enabled).

The code will use the page at NOTION_TEST_PAGE_ID to generate a temporary environment with the Notion objects to be tested, which will be deleted at the end of the session.

Requirements

This package supports the following minimum versions:

• Python >= 3.7
• httpx >= 0.15.0

Earlier versions may still work, but we encourage people building new applications to upgrade to the current stable.
