Overview - Corsair

Use Notion through Corsair: one client, typed API calls, local DB sync, and incoming webhooks. What you get:

14 typed API operations
4 synced entities (blocks, databases, pages, users) for fast .search() / .list()
3 incoming webhook event types

Setup

Install

npm install corsair @corsair-dev/notion

yarn add corsair @corsair-dev/notion

pnpm install corsair @corsair-dev/notion

bun add corsair @corsair-dev/notion

Add the plugin

corsair.ts

import Database from 'better-sqlite3';
import { createCorsair } from 'corsair';
import { notion } from '@corsair-dev/notion';

export const corsair = createCorsair({
	plugins: [
		notion({
			authType: 'managed',
		}),
	],
	database: new Database('corsair.db'),
	kek: process.env.CORSAIR_KEK!,
	hub: {
		projectApiKey: process.env.CORSAIR_API_KEY!,
		signingSecret: process.env.CORSAIR_SIGNING_SECRET!,
	},
});

Multi-tenancy is the default — scope calls with corsair.withTenant(id). See Quick start for KEK + Hub keys, and Multi-tenancy for account isolation.

Choose authentication

Managed OAuth (Recommended)
API Key
OAuth 2.0

No setup required. Corsair hosts the OAuth app for Notion — your tenants connect through Hub when they sign in.Provider walkthrough: Get Credentials.

notion({
	authType: 'managed',
})

More: Managed OAuth

No setup required yet. When you make your first request as a tenant, Corsair prompts for the API key.Provider walkthrough: Get Credentials.

notion()

More: API Key

Open hub.corsair.dev, navigate to your project, and enter the client ID and client secret from your Notion OAuth app.Provider walkthrough: Get Credentials.

notion({
	authType: 'oauth_2',
})

More: OAuth 2.0

Connect a tenant

Mint a connect link and send the tenant to it. Hub hosts the page and delivers the result to your app — see Connect / OAuth.

const { connectUrl } = await corsair.manage.connect.createLink({
	plugin: 'notion',
	tenantId: 'acme',
});
// redirect the user's browser to connectUrl

Example API calls

Search pages

const tenant = corsair.withTenant('acme');
await tenant.notion.api.pages.searchPage({});

Create a new page

const tenant = corsair.withTenant('acme');
await tenant.notion.api.pages.createPage({
	parent: { type: 'database_id', database_id: 'd9824bdc-8445-4327-be8b-5b47500af6ce' },
});

See the full list on the API page.

Query synced data

Search synced pages without hitting Notion’s API.

const tenant = corsair.withTenant('acme');
const rows = await tenant.notion.db.pages.search({
	data: { archived: false },
	limit: 50,
});

Synced entities: blocks, databases, pages, users. See Database for filters and operators.

Webhooks

Fires when a page is created in a Notion database.

notion({
    webhookHooks: {
        databasePages: {
            pageCreated: {
                after: async (ctx, result) => {
                    const pageId = result.data?.entity?.id;
                    console.log('New Notion page created with ID:', pageId);
                }
            },
        },
    },
})

Mount your framework handler once (see Frameworks), then point the provider at that URL. Full event list: Webhooks. Concepts: Webhooks, Hooks.
