- Approved deletes.
Here are the Klaviyo Flows actions we reach for in n8n every week, with the gotchas we learned the hard way.
Create
Idempotency key required. Store the Klaviyo Flows ID for reference.
Update
Merge, never overwrite. Track prior state in Postgres for audit.
Search
Prefer indexed lookups; avoid unfiltered scans that hit rate limits.
Delete
Soft-delete when possible. Hard-delete only via a dedicated approval workflow.
