Workflow name
Automate consent dispute handling with GPT-4o, Google Sheets, Gmail & Slack

πŸ“˜ Description

This workflow automates the full lifecycle of a data-consent complaint: receiving the complaint, validating the payload, normalizing the data into a clean ticket format, storing it in a compliance sheet, generating a formal acknowledgement email for the user, and sending an internal Slack alert for the compliance team. Everything moves from intake β†’ classification β†’ communication β†’ escalation with zero manual handling. AI-generated messages follow DPDP-compliant tone and structure.

βš™οΈ What This Workflow Does (Step-by-Step)

▢️ Receive Consent Complaint (Webhook) Accepts a POST request containing complaint details: name, email, issue type, description, and metadata.

πŸ” Check Required Fields (IF) Validates that the complaint includes a non-empty description. Valid β†’ processed Invalid β†’ logged to a separate sheet.

🧹 Clean & Normalize Complaint Data (Code) Constructs a unified ticket object with: auto-generated ticketId normalized fields (action, email, issueType, description) priority scoring timestamp source metadata Sets default status to Open.

πŸ“„ Log Invalid Complaint Records (Google Sheets) Stores incomplete submissions for later review.

πŸ“₯ Store Complaint Ticket in Consent Dispute Sheet (Google Sheets) Appends the cleaned ticket into the Consent Dispute sheet including all metadata for traceability.

🧠 Generate Acknowledgement Email (AI) Creates a DPDP-compliant support email: mentions user name references ticket ID summarizes issue sets response window (48–72 hours) avoids legal or internal disclosures uses formal, respectful tone

βš™οΈ Configure GPT-4o – Email Generator Supplies the AI model for email generation.

πŸ“ Extract Email Subject + Body (Code) Splits the AI-generated email into structured fields: subject and message.

πŸ“§ Send Acknowledgement Email to User (Gmail) Delivers the formatted acknowledgement directly to the user who filed the complaint.

βš™οΈ Configure GPT-4o – Slack Summary Model Supplies the AI model for internal Slack summary generation.

πŸ”” Generate Slack Incident Summary (AI) Produces an internal, action-focused Slack message containing:

  • ticket ID
  • user details
  • issue type
  • description
  • timestamp
  • priority recommended next step No greetings, no email formatting.

πŸ“‘ Slack – Notify Compliance Team Sends the incident summary to the assigned Slack user or channel for quick action by compliance.
