Notion

Use this guide to choose current Notion tools and triggers, understand integration access, and troubleshoot connection or response-size issues.

Use current Notion tools and triggers

Retrieve pages with the current tool slug. NOTION_GET_PAGE is not the current valid slug. Use NOTION_RETRIEVE_PAGE, and verify available Notion tools from the marketplace/tool listing.

Fetch Notion data with the current tool slug. NOTION_FETCH_NOTION_DATA is not valid. Use NOTION_FETCH_DATA instead.

Choose the trigger that matches the Notion event. The current Notion catalog includes separate triggers for page creation, page content updates, page property updates, and data-source schema updates. Choose the trigger that matches the event rather than expecting a page-created trigger to fire for edits. Fetch the current trigger catalog before implementation and use the exact returned slug.

Configure Notion access and connected accounts

Grant page and database access through the Notion integration. Notion does not model access as normal OAuth scopes. Page/database access is granted per Notion integration/OAuth client ID through Notion “Capabilities” and workspace grants. If multiple Composio auth configs use the same underlying Notion integration, page authorization can overlap.

Treat auth config selection as connection lookup behavior. Existing connected accounts under a different auth config continue to refresh and work. Specifying an auth config affects which connection get/use functions look for; it does not rewrite refresh behavior for already-valid connected accounts.

Troubleshoot Notion connections and large responses

Check for a revoked integration when Notion returns 401 or refresh fails. A Notion refresh failure with “Invalid refresh token” is usually a token revocation issue. Common causes are the user disconnecting the integration in Notion settings or a workspace admin removing/blocking the integration.

Keep Notion responses focused. Large response payloads and overly complex structures can degrade agent behavior. Prefer narrower fetches/filters where available and track product improvements for simpler response structures.
