Handle GDPR access and erasure emails with Gmail, GPT-4o, Supabase and Airtable
Go to WorkflowDescription
š How it works
Handles GDPR Article 15 (access) and Article 17 (erasure) requests
end-to-end ā from inbound email to legally-compliant response ā with
zero manual intervention and a full audit trail.
š¬ Monitors Gmail inbox for incoming data subject requests
š¤ AI Agent classifies the request (access or erasure), extracts the
requester email and data subject email with structured JSON output
šļø Queries Supabase for all personal data records matching the subject
š Queries Airtable CRM for matching contact records
š Second AI Agent compiles all found data into a GDPR-compliant HTML report
āļø Access requests ā sends a full data report to the requester
šļø Erasure requests ā deletes records from both Supabase and Airtable,
then sends a deletion confirmation
š Logs every request to Google Sheets with timestamp for your audit trail
š ļø Set up steps
