Notion Overview#

Notion's API allows for the creation, reading, updating, and deleting of pages, databases, and their contents within Notion. Using Pipedream's platform, you can build workflows that connect Notion with various other services to automate tasks such as content management, task tracking, and data synchronization. With Pipedream's serverless execution, you can trigger these workflows on a schedule, or by external events from other services, without managing any infrastructure.

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
Notion	`notion`	`app`	This component uses the Notion app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
	`timer`	`$.interface.timer`
Database ID	`databaseId`	`string`	Select a value from the drop down menu.
Include New Pages	`includeNewPages`	`boolean`	Set to `true` to emit events when pages are created. Set to `false` to ignore new pages.
Property Types	`properties`	`string[]`	Select a value from the drop down menu.

Trigger Authentication#

Notion uses OAuth authentication. When you connect your Notion account, Pipedream will open a popup window where you can sign into Notion and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Notion API.

Pipedream requests the following authorization scopes when you connect your account:
