Third-Party Integrations

Notion Integration

Notion OAuth only supports HTTPS, so local deployments must use internal integration.

Configure environment variables

Set in .env:

NOTION_INTEGRATION_TYPE=internal
NOTION_INTERNAL_SECRET=your_internal_secret_here

For public integration (HTTPS only):

NOTION_INTEGRATION_TYPE=public
NOTION_CLIENT_SECRET=oauth_client_secret
NOTION_CLIENT_ID=oauth_client_id

Get credentials from Notion Integrations.
