Event types & delivery

Webhooks currently notify you about changes to pages and databases — such as when a new page is created, a title is updated, or someone changes a database schema. The events themselves do not contain the full content that changed. Instead, the webhook acts as a signal that something changed, and it’s up to your integration to follow up with a call to the Notion API to retrieve the latest content.

For example, let’s say a user updates the title of a page. You’ll receive a page.content_updated webhook event with the ID of the page that changed. From there, your integration can use the retrieve a page endpoint to fetch the latest page content — including the new title.

Event types

Event properties

All webhook event types share the following shape of properties:

FieldTypeDescription
idUUIDThe unique ID of the webhook event
timestampStringISO 8601 formatted time at which the event occurred. This field can be used to order events on your side
workspace_idUUIDThe workspace ID where the event originated from
subscription_idUUIDThe ID of the webhook subscription
integration_idUUIDAssociated integration ID the subscription is set up with
typeStringType of the event, e.g. page.created
authorsArrayArray of JSON objects with the ID (id) and type (type) of the author who performed the action that caused this webhook. type can be "person", "bot", or "agent".

This helps you identify, for example, the API bot that created a page, or the Notion user that edited the schema of a database.

This will typically be an array of length 1, except for aggregated events when more than 1 user makes changes in a short time window.

More details on a bot or person can be retrieved by ID in the Users API after receiving a webhook.
accessible_byArrayArray of JSON objects with the ID (id) and type (type) of each user that owns a bot connection to the integration_id and has access to the webhook's entity.

This field is only populated for public integrations, to help identify relevant user connections.

The type of each entry is always "person".
attempt_numbernumberA number ranged from 1 - 8 that indicates the attempt number of the current event delivery
entityObjectID (id) and type (type) of the object that triggered the event. The type can be "page", "block", or "database".
dataObjectAdditional, event-specific data.

Supported webhook event types

Notion currently supports the following webhook event types. Each event represents a meaningful change to content in a workspace — such as the creation of a page, a schema update, or a new comment.

📘

More event types may be added in the future

If Notion supports additional event types or resources, your subscription won't update automatically to receive them.

To subscribe to more event types or change the existing types your endpoint is receiving, update your subscription in the integration page's Webhooks tab.

Below, you’ll find the list of available type values, a short description of what each event represents, and whether the event is aggregated. Aggregated events group multiple changes into a single notification to reduce noise and improve efficiency.

TypeDescriptionIs aggregated?
page.content_updatedTriggered when the content of a page changes — for example
adding or removing a block on the page.		Yes

page.properties_updatedTriggered when a page's property is updated.Yes
page.undeletedTriggered when a page is restored from the trash.Yes

adding or removing a child page.		Yes
database.createdTriggered when a new database is created.Yes
database.deletedTriggered when a database is moved to the trash.Yes
database.movedTriggered when a database is moved to another location.Yes
database.schema_updatedTriggered when a database's schema is updated — for example,
adding or removing a database property.		Yes
database.undeletedTriggered when a database is restored from the trash.Yes
comment.createdTriggered when a new comment or suggested edit is added to a page or blockNo
comment.deletedTriggered when a comment is deleted.No
comment.updatedTriggered when a comment is edited.No

🗒️

What does “aggregated” mean?

For high-frequency events like page.content_updated, Notion batches changes that occur within a short time window into a single webhook event. Events such as page.created, page.deleted, page.undeleted occur in quick succession, you may only recieve the most meaningful result event -- or none at all if the state returns to its original one.

Event aggregration helps reduce redundant calls and improves reliability. Aggregated events may have a slight delivery delay (typically under one minute).

Event delivery

Events should be delivered within 5 minutes of their occurrences. Most should be be delivered within a minute. Here are a few things to keep in mind when consuming webhook events.

Event aggregation

Certain events that occur frequently, like page.content_updated, are aggregated by their entity within a brief time window. As a result, there may be a slight delay between the first occurrence of an event and its delivery to your webhook URL.

Event ordering

Events may arrive in a different order than they occurred. If event ordering is critical for your workflows, use the event's timestamp field to reorder them. Also, webhook events may not show the most current state of the data. We strongly recommend fetching the latest data from the API.

Delivery retries

We aim for at-most-once event delivery. If your webhook endpoint fails to acknowledge receipt of an event, we will retry delivery up to 8 times using an exponential backoff schedule. The final retry attempt occurs approximately 24 hours after the initial event trigger.

Sample event payloads

Notion currently supports the following event types. We've added an example payload to describe the shape of each event.

Linked databases

For linked databases, the entity.type is "block" instead of "database".

If you retrieve this block in the API, it has a type of "child_database".
