n8n Webhook Workflow: Privaro PII Tokenization + GPT-4o

Secure support triage with Privaro PII tokenization + GPT-4o (via n8n webhook)

This n8n workflow receives incoming support tickets through a webhook, automatically tokenizes and vaults sensitive PII with Privaro, routes the protected text to GPT-4o-mini for classification and reply drafting, then returns the detokenized answer—along with Privaro risk and audit metadata.

What this workflow does

• Receives ticket messages via a POST webhook endpoint (expects a JSON body with body.message).
• Generates a unique conversation ID to keep reversible tokenization linked to later detokenization.
• Uses Privaro Protect to detect and strip PII, replacing it with reversible tokens and recording detection details.
• Sends the protected ticket to GPT-4o-mini through Privaro’s relay using triage instructions, then detokenizes the model’s response.
• Returns results to the caller, including the assistant response plus a Privaro risk score and an audit log ID in the webhook response.

Use cases

• Automating first-line support while reducing exposure to PII in prompts.
• Implementing privacy-aware customer service triage for SaaS operators who must log and audit sensitive data handling.
• Routing support tickets to GPT-4o-mini with protection guarantees and traceable risk/audit outputs.

Technical details

• n8n nodes: Code, Webhook, n8n-nodes-privaroprivaro (Privaro Protect + Privaro Chat Completion via relay), Respond to Webhook.
• Setup requirements:
  • Create a Privaro API credential in n8n using your Privaro API key.
  • Set a matching Privaro Pipeline ID in both Privaro nodes (Protect and Chat Completion).
  • Deploy the workflow and configure your support system to POST payloads with body.message.
