Auto-Deduplication for Daily Webhook Pushes
Clay deduplicates data at insert time by comparing incoming rows against existing records in your destination table.
How It Works
- Compares new records against existing data using a deduplication key (email, domain, ID, etc.)
- Only inserts records that don't already exist in the table
- Example: If Day 1 has 50 results and Day 2 has 52 results with 50 duplicates, only the 2 new records are added
Requirements
- The destination table must be active
- The deduplication key must remain consistent across pushes
