Notion

OAuth 2.0 provider for Notion.

Also see the OAuth 2.0 guide.

Initialization

import { Notion } from "arctic";

const notion = new Notion(clientId, clientSecret, redirectURI);

Create authorization URL

import { generateState } from "arctic";

const state = generateState();
const url = notion.createAuthorizationURL(state);

Validate authorization code

validateAuthorizationCode() will either return an OAuth2Tokens, or throw one of OAuth2RequestError, ArcticFetchError, or a standard Error (parse errors). Notion will only return an access token (no expiration).

import { OAuth2RequestError, ArcticFetchError } from "arctic";

try {
	const tokens = await notion.validateAuthorizationCode(code);
	const accessToken = tokens.accessToken();
} catch (e) {
	if (e instanceof OAuth2RequestError) {
		// Invalid authorization code, credentials, or redirect URI
		const code = e.code;
		// ...
	}
	if (e instanceof ArcticFetchError) {
		// Failed to call `fetch()`
		const cause = e.cause;
		// ...
	}
	// Parse error
}

Get user profile

Use the /users/me endpoint.

const response = await fetch("https://api.notion.com/v1/users/me", {
	headers: {
		Authorization: `Bearer ${accessToken}`
	}
});
const user = await response.json();
