Klaviyo Data Handling

Klaviyo Data Handling

Overview

Handle profile data, PII, and privacy compliance with Klaviyo's Data Privacy API, GDPR right-to-deletion, CCPA requests, and safe logging patterns. This skill covers five workflows: GDPR profile deletion, Data Subject Access Requests (DSAR), PII redaction in logs, consent management, and compliance audit logging.

The GDPR deletion skeleton is inline below. The deeper step-by-step code — DSAR export, PII redaction, consent management, and audit logging — lives in references/implementation.md so this file stays scannable. Read the summary here, then drill into the reference for full copy-ready code.

Prerequisites

• klaviyo-api SDK installed
• API key with data-privacy:write scope (for deletion requests)
• Understanding of GDPR/CCPA requirements
• Audit logging infrastructure

Klaviyo Data Privacy API

Klaviyo provides a dedicated Data Privacy API for GDPR/CCPA profile deletion. When you delete a profile via this API, Klaviyo performs a full GDPR erasure — the profile is permanently removed and cannot be recovered.

Instructions

The workflow has five steps. Step 1 (deletion) is shown in full here because it is the highest-risk, most-requested operation. Steps 2–5 follow the same session pattern and are fully implemented in references/implementation.md.

Step 1: GDPR Profile Deletion (Right to Erasure)

Request deletion with exactly one identifier (email, phone, or profile ID). Providing more than one returns an error. Deletion is irreversible, so always audit-log the request.

import { ApiKeySession, DataPrivacyApi } from 'klaviyo-api';

const session = new ApiKeySession(process.env.KLAVIYO_PRIVATE_KEY!);
const dataPrivacyApi = new DataPrivacyApi(session);

async function requestProfileDeletion(email: string): Promise<void> {
  await dataPrivacyApi.requestProfileDeletion({
    data: {
      type: 'data-privacy-deletion-job',
      attributes: {
        profile: { data: { type: 'profile', attributes: { email } } },
      },
    },
  });

  await auditLog({
    action: 'GDPR_DELETION_REQUESTED',
    identifier: email,
    service: 'klaviyo',
    timestamp: new Date().toISOString(),
  });
}

await requestProfileDeletion('user-wants-deletion@example.com');

The multi-identifier form (email / phone / profile ID with validation) is in references/implementation.md § Step 1.

Step 2: Data Subject Access Request (DSAR)

Export every profile attribute, event, and list membership for a subject (GDPR Article 15) using ProfilesApi + EventsApi. Full exportProfileData() in references/implementation.md § Step 2.

Step 3: PII Detection and Redaction in Logs

Wrap every log of a Klaviyo response with redactPII() / redactObject() so emails, phone numbers, and API keys never land in plaintext logs. Full patterns in references/implementation.md § Step 3.

Step 4: Consent Management

Record marketing consent with a consentTimestamp on every subscribe call, and audit-log the source. Full recordConsent() in references/implementation.md § Step 4.

Step 5: Audit Logging

Persist every privacy action to a retained audit store (7-year retention per GDPR). Full auditLog() and schema in references/implementation.md § Step 5.

Output

Applying this skill produces:

• A requestProfileDeletion() call that submits an irreversible GDPR erasure job to Klaviyo and writes a GDPR_DELETION_REQUESTED audit entry.
• A DSAR export object containing the subject's profile attributes, event history, and list memberships (GDPR Article 15 response payload).
• Log output with PII replaced by [REDACTED:type] markers, e.g. Profile data: { email: 'joh***' }.
• Consent records carrying an ISO-8601 consentTimestamp plus a matching CONSENT_RECORDED audit entry.
• Audit entries retained for 7 years, each carrying action, identifier, service, and timestamp.

Error Handling

Examples

Delete a profile on a right-to-be-forgotten request:

await requestProfileDeletion('user-wants-deletion@example.com');
// → GDPR erasure job submitted; GDPR_DELETION_REQUESTED audit entry written

Export a subject's data for a DSAR (see references/implementation.md § Step 2):

const bundle = await exportProfileData('subject@example.com');
// → { profile: {...}, events: [...], lists: [...] }

Redact PII before logging an API response (see references/implementation.md § Step 3):

console.log('Profile data:', redactObject(profile.attributes));
// → Profile data: { email: 'joh***', firstName: 'Jan***' }

Full, copy-ready versions of every example live in references/implementation.md.
