Personal connection
Each team member connects their own Notion account. On Belay stores a personal credential per user, so Claude accesses data scoped to that individual's permissions.
How to connect
Prerequisites: You'll need a Notion account with access to the Notion resources you want to connect.
Click "Connect with OAuth" below to authorize On Belay to access your Notion workspace. You'll be redirected to Notion to approve the connection and select which pages and databases to share — no credentials to copy or paste.
Ready to connect?
Sign in to On Belay and open the Integrations page to add Notion.
Permissions (scopes)
These are the data scopes On Belay can be granted for Notion. Your org admin controls which scopes are enabled per group.
| Scope | Description | Access |
|---|---|---|
pages:read | Read pages | Read only |
pages:write | Write pages | Read / Write |
databases:read | Read databases | Read only |
databases:write | Write databases | Read / Write |
users:read | Read users | Read only |
Troubleshooting
"redirect_uri_mismatch" error during OAuth
Your OAuth app's authorized redirect URIs don't include the On Belay callback URL. Add
https://app.onbelay.ai/api/oauth-callback/notion to the allowed redirect URIs in your OAuth app settings."invalid_scope" error
The API or scope isn't enabled in your cloud project. For Google integrations, make sure the relevant API (e.g. Google Ads API, Search Console API) is enabled in Google Cloud Console for your project.
Connected but Claude can't access data
Check that your group has been granted access to this integration in On Belay → Groups → [your group] → Integrations. Also verify the specific scopes your group is permitted to use match what your query requires.
