Lead Payload Deduplication and Schema Normalization

How it works

1. 1.Generate a representative lead batch with duplicate keys and nested objects.
2. 2.Flatten nested schemas, sanitize fields, and resolve duplicates by timestamp.
3. 3.Branch clean leads and rejected items via an If routing node.
4. 4.Tag clean leads as CLEAN_APPROVED and invalid entries as REJECTED_AUDIT.
5. 5.Compile the final unified clean lead array as the terminal workflow output.

Use cases

• Cleansing incoming bulk webhook lead submissions prior to CRM ingestion.
• Eliminating duplicate records in marketing lists to reduce operation quotas.
• Transforming heterogeneous nested payloads into standard flat records.

Requirements

• n8n environment version 2.42.6 or later.
• Zero external credentials required; operates entirely using native nodes.

Setup and testing in n8n

1. Import the workflow JSON into your n8n workspace.
2. Click 'Test workflow' to execute the pipeline.
3. Verify that Compile Final Pipeline Output yields clean normalized leads for LEAD-101 and LEAD-103.
4. Check the rejected branch in Audit Rejected Leads to inspect the rejection causes.
