Notion Integration Security Baseline

Overview

Establish a security baseline for Notion credentials, capabilities, content access, webhooks, writes, logs, and tenant isolation.. This workflow produces an auditable decision or artifact before any live action.

Prerequisites

• Current first-party Notion documentation and the selected integration's tested API-version contract.
• A named workspace owner, content or data owner, and operation owner.
• Synthetic or approved non-production fixtures with secrets and workspace content removed.

Current Contract

Security spans bearer-token custody, OAuth state and workspace binding, minimum capabilities, explicit content sharing, webhook signature verification, version-safe parsing, idempotent writes, telemetry redaction, and incident revocation. Recheck the dated evidence map before relying on mutable fields, endpoints, versions, limits, or delivery behavior.

Authentication

Store credentials only in the approved secret system, encrypt public-connection tokens at rest, separate environments and tenants, and test rotation and revocation.
