Login with Notion

To enable Notion Auth for your project, you need to set up a Notion Application and add the Application OAuth credentials to your Supabase Dashboard.

Overview

Setting up Notion logins for your application consists of 3 parts:

Create and configure a Notion Application Notion Developer Portal
Retrieve your OAuth client ID and OAuth client secret and add them to your Supabase Project
Add the login code to your Supabase JS Client App

notion.so

Once logged in, go to notion.so/my-integrations and create a new integration.
When creating your integration, ensure that you select "Public integration" under "Integration type" and "Read user information including email addresses" under "Capabilities".
You will need to add a redirect uri, see Add the redirect uri
Once you've filled in the necessary fields, click "Submit" to finish creating the integration.

notion.so

After selecting "Public integration", you should see an option to add "Redirect URIs".

notion.so

The next step requires a callback URL, which looks like this: https://<project-ref>.supabase.co/auth/v1/callback

Go to your Supabase Project Dashboard
Click on the Authentication icon in the left sidebar
Click on Providers under the Configuration section
Click on Notion from the accordion list to expand and you'll find your Callback URL, you can click Copy to copy it to the clipboard

Once you've created your notion integration, you should be able to retrieve the "OAuth client ID" and "OAuth client secret" from the "OAuth Domain and URIs" tab.

notion.so

Go to your Supabase Project Dashboard
In the left sidebar, click the Authentication icon (near the top)
Click on Providers under the Configuration section
Click on Notion from the accordion list to expand and turn Notion Enabled to ON
Enter your Notion Client ID and Notion Client Secret saved in the previous step
Click Save

When your user signs in, call signInWithOAuth() with notion as the provider:


_10async function signInWithNotion() {
_10  const { data, error } = await supabase.auth.signInWithOAuth({
_10    provider: 'notion',
_10  })
_10}

When your user signs out, call signOut() to remove them from the browser session and any objects from localStorage:


_10async function signOut() {
_10  const { error } = await supabase.auth.signOut()
_10}
