A production-grade automation pipeline syncing Airtable records into native n8n Data Tables using polling triggers and idempotent upserts, overcoming nested field schemas, array coercion, and race condition traps.
- Watches Airtable Last Modified Time on all editable fields to capture creates and updates in a single trigger
- Code node flattens nested fields, stringifies multi-select arrays, and coerces empty numbers with safe fallbacks
- Idempotent upsert matching strictly on stable airtable_record_id to eliminate duplicates
- Includes step-by-step verification checklist and error handling
Built with: n8n, Airtable, n8n Data Tables, JavaScript (Code Node), Upsert Architecture, Data Pipelines
