Frequently Asked Questions

Why does Notion unauthorized error 401 keep happening?
This error typically recurs when integrations are accidentally removed from pages, API tokens expire, or workspace permissions change. To prevent it, avoid removing integrations from the Connections settings and ensure all team members understand not to remove shared integrations from pages.
How do I find my Notion API token?
Go to https://www.notion.so/my-integrations, select your integration, and click 'Show' next to the Internal Integration Token field. Copy this token and paste it into your third-party application's API key or token field.
Can I use the same Notion integration for multiple pages?
Yes, a single Notion integration can access multiple pages, but it must be individually shared with each page or database you want it to access. Add the integration to each page through the Share menu.
What's the difference between Notion error 401 and 403?
Error 401 (unauthorized) means your API token is invalid or missing, while error 403 (forbidden) means your token is valid but lacks permission to access the specific resource. For 401, regenerate your token; for 403, check page sharing settings.
How do I create a new Notion integration if mine was deleted?
Visit https://www.notion.so/my-integrations, click 'Create new integration', provide a name and workspace, then copy the generated token. Remember to share this new integration with your Notion pages through the Share menu.
