notion-py

Unofficial Python 3 client for Notion.so API v3.

Read more about Notion and Notion-py on Jamie's blog

Usage

Quickstart

Note: the latest version of notion-py requires Python 3.5 or greater.

pip install notion

from notion.client import NotionClient

# Obtain the `token_v2` value by inspecting your browser cookies on a logged-in (non-guest) session on Notion.so
client = NotionClient(token_v2="<token_v2>")

# Replace this URL with the URL of the page you want to edit
page = client.get_block("https://www.notion.so/myorg/Test-c0d20a71c0944985ae96e661ccc99821")

print("The old title is:", page.title)

# Note: You can use Markdown! We convert on-the-fly to Notion's internal formatted text data structure.
page.title = "The title has now changed, and has *live-updated* in the browser!"

Concepts and notes

Updating records

We keep a local cache of all data that passes through. When you reference an attribute on a Record, we first look to that cache to retrieve the value. If it doesn't find it, it retrieves it from the server. You can also manually refresh the data for a Record by calling the refresh method on it. By default (unless we instantiate NotionClient with monitor=False), we also subscribe to long-polling updates for any instantiated Record, so the local cache data for these Records should be automatically live-updated shortly after any data changes on the server. The long-polling happens in a background daemon thread.

Example: Traversing the block tree

for child in page.children:
    print(child.title)

print("Parent of {} is {}".format(page.id, page.parent.id))

Example: Adding a new node

from notion.block import TodoBlock

newchild = page.children.add_new(TodoBlock, title="Something to get done")
newchild.checked = True

Example: Deleting nodes

# soft-delete
page.remove()

# hard-delete
page.remove(permanently=True)

Example: Create an embedded content type (iframe, video, etc)

from notion.block import VideoBlock

video = page.children.add_new(VideoBlock, width=200)
# sets "property.source" to the URL, and "format.display_source" to the embedly-converted URL
video.set_source_url("https://www.youtube.com/watch?v=oHg5SJYRHA0")

Example: Create a new embedded collection view block

collection = client.get_collection(COLLECTION_ID) # get an existing collection
cvb = page.children.add_new(CollectionViewBlock, collection=collection)
view = cvb.views.add_new(view_type="table")

# Before the view can be browsed in Notion, 
# the filters and format options on the view should be set as desired.
# 
# for example:
#   view.set("query", ...)
#   view.set("format.board_groups", ...)
#   view.set("format.board_properties", ...)

Example: Moving blocks around

# move my block to after the video
my_block.move_to(video, "after")

# move my block to the end of otherblock's children
my_block.move_to(otherblock, "last-child")

# (you can also use "before" and "first-child")

Example: Subscribing to updates

(Note: Notion->Python automatic updating is currently broken and hence disabled by default; call my_block.refresh() to update, in the meantime, while monitoring is being fixed)

We can "watch" a Record so that we get a callback whenever it changes. Combined with the live-updating of records based on long-polling, this allows for a "reactive" design, where actions in our local application can be triggered in response to interactions with the Notion interface.


# define a callback (note: all arguments are optional, just include the ones you care about)
def my_callback(record, difference):
    print("The record's title is now:" record.title)
    print("Here's what was changed:")
    print(difference)

# move my block to after the video
my_block.add_callback(my_callback)

Example: Working with databases, aka "collections" (tables, boards, etc)

Here's how things fit together:

Note: For convenience, we automatically map the database "columns" (aka properties), based on the schema defined in the Collection, into getter/setter attributes on the CollectionRowBlock instances. The attribute name is a "slugified" version of the name of the column. So if you have a column named "Estimated value", you can read and write it via myrowblock.estimated_value. Some basic validation may be conducted, and it will be converted into the appropriate internal format. For columns of type "Person", we expect a User instance, or a list of them, and for a "Relation" we expect a singular/list of instances of a subclass of Block.

# Access a database using the URL of the database page or the inline block
cv = client.get_collection_view("https://www.notion.so/myorg/8511b9fc522249f79b90768b832599cc?v=8dee2a54f6b64cb296c83328adba78e1")

# List all the records with "Bob" in them
for row in cv.collection.get_rows(search="Bob"):
    print("We estimate the value of '{}' at {}".format(row.name, row.estimated_value))

# Add a new record
row = cv.collection.add_row()
row.name = "Just some data"
row.is_confirmed = True
row.estimated_value = 399
row.files = ["https://www.birdlife.org/sites/default/files/styles/1600/public/slide.jpg"]
row.person = client.current_user
row.tags = ["A", "C"]
row.where_to = "https://learningequality.org"

# Run a filtered/sorted query using a view's default parameters
result = cv.default_query().execute()
for row in result:
    print(row)

# Run an "aggregation" query
aggregations = [{
    "property": "estimated_value",
    "aggregator": "sum",
    "id": "total_value",
}]
result = cv.build_query(aggregate=aggregate_params).execute()
print("Total estimated value:", result.get_aggregate("total_value"))

# Run a "filtered" query (inspect network tab in browser for examples, on queryCollection calls)
filter_params = {
    "filters": [{
        "filter": {
            "value": {
                "type": "exact",
                "value": {"table": "notion_user", "id": client.current_user.id}
            },
            "operator": "person_contains"
        },
        "property": "assigned_to"
    }],
    "operator": "and"
}
result = cv.build_query(filter=filter_params).execute()
print("Things assigned to me:", result)

# Run a "sorted" query
sort_params = [{
    "direction": "descending",
    "property": "estimated_value",
}]
result = cv.build_query(sort=sort_params).execute()
print("Sorted results, showing most valuable first:", result)

Note: You can combine filter, aggregate, and sort. See more examples of queries by setting up complex views in Notion, and then inspecting the full query: cv.get("query2").

You can also see more examples in action in the smoke test runner. Run it using:

python run_smoke_test.py --page [YOUR_NOTION_PAGE_URL] --token [YOUR_NOTION_TOKEN_V2]

Example: Lock/Unlock A Page

from notion.client import NotionClient

# Obtain the `token_v2` value by inspecting your browser cookies on a logged-in session on Notion.so
client = NotionClient(token_v2="<token_v2>")

# Replace this URL with the URL of the page or database you want to edit
page = client.get_block("https://www.notion.so/myorg/Test-c0d20a71c0944985ae96e661ccc99821")

# The "locked" property is available on PageBlock and CollectionViewBlock objects
# Set it to True to lock the page/database
page.locked = True
# and False to unlock it again
page.locked = False

Example: Set the current user for multi-account user

from notion.client import NotionClient
client = NotionClient(token_v2="<token_v2>")

# The initial current_user of a multi-account user may be an unwanted user
print(client.current_user.email) # → not_the_desired@email.co.jp

# Set current_user to the desired user
client.set_user_by_email('desired@email.com')
print(client.current_user.email) # → desired@email.com

# You can also set the current_user by uid.
client.set_user_by_uid('<uid>')
print(client.current_user.email) # → desired@email.com

Quick plug: Learning Equality needs your support!

If you'd like to support notion-py development, please consider donating to my open-source nonprofit, Learning Equality, since when I'm not working on notion-py, it probably means I'm heads-down fundraising for our global education work (bringing resources like Khan Academy to communities with no Internet). COVID has further amplified needs, with over a billion kids stuck at home, and over half of them without the connectivity they need for distance learning. You can now also support our work via GitHub Sponsors!
