Notion Advanced Troubleshooting

Overview

Deep debugging techniques for Notion API issues that resist standard fixes. Covers API response inspection with request IDs, permission chain tracing through page hierarchies, property type mismatch detection against database schemas, pagination edge cases with cursor validation, and block nesting limit violations (max depth of 3 levels via API). Uses Client from @notionhq/client and raw curl for comparison testing.

Prerequisites

• @notionhq/client v2.x installed (npm install @notionhq/client)
• Python: notion-client installed (pip install notion-client)
• curl available for raw API testing
• NOTION_TOKEN environment variable set (internal integration token starting with ntn_)
• Pages/databases shared with your integration via Notion UI

Instructions

Step 1: API Response Inspection with Request ID Tracking

Every Notion API response includes an x-request-id header. Capture it for debugging and support tickets.
