ClickUp Data Handling

Overview

Handle sensitive data from ClickUp API v2 responses. ClickUp task data often contains PII (assignee emails, names) and business-sensitive information (task descriptions, comments, custom field values).

ClickUp Data Classification

Data Source	PII Risk	Handling
/user response	High (email, username)	Redact in logs
/team members	High (emails, names)	Minimize; cache only IDs
Task assignees	Medium (user IDs, names)	Aggregate when possible
Task descriptions	Variable (may contain PII)	Scan before storing
Custom field values	High (email, phone fields)	Encrypt at rest
Comments	Variable (user content)	Scan before logging
Webhook payloads	Medium (user objects in history)	Redact before queuing

PII Detection in ClickUp Data

interface PiiFindings {
  field: string;
  type: string;
  value: string;
}

const PII_PATTERNS = [
  { type: 'email', regex: /[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/g },
  { type: 'phone', regex: /\b\d{3}[-.]?\d{3}[-.]?\d{4}\b/g },
  { type: 'ssn', regex: /\b\d{3}-\d{2}-\d{4}\b/g },
];

function scanClickUpTaskForPii(task: any): PiiFindings[] {
  const findings: PiiFindings[] = [];

  // Check description
  for (const pattern of PII_PATTERNS) {
    const matches = (task.description ?? '').matchAll(pattern.regex);
    for (const m of matches) {
      findings.push({ field: 'description', type: pattern.type, value: m[0] });
    }
  }

  // Check custom fields
  for (const cf of task.custom_fields ?? []) {
    if (cf.type === 'email' && cf.value) {
      findings.push({ field: `custom_field:${cf.name}`, type: 'email', value: cf.value });
    }
    if (cf.type === 'phone' && cf.value) {
      findings.push({ field: `custom_field:${cf.name}`, type: 'phone', value: cf.value });
    }
  }

  // Check assignees
  for (const assignee of task.assignees ?? []) {
    if (assignee.email) {
      findings.push({ field: 'assignee', type: 'email', value: assignee.email });
    }
  }

  return findings;
}

Redaction for Logging

function redactClickUpResponse(data: any): any {
  const redacted = JSON.parse(JSON.stringify(data));

  // Redact user objects
  const redactUser = (user: any) => {
    if (user?.email) user.email = '[REDACTED]';
    if (user?.username) user.username = user.username.substring(0, 2) + '***';
  };

  // Task-level redaction
  if (redacted.assignees) redacted.assignees.forEach(redactUser);
  if (redacted.creator) redactUser(redacted.creator);

  // Webhook payload redaction
  if (redacted.history_items) {
    for (const item of redacted.history_items) {
      if (item.user) redactUser(item.user);
    }
  }

  // Custom fields with PII types
  if (redacted.custom_fields) {
    for (const cf of redacted.custom_fields) {
      if (['email', 'phone'].includes(cf.type) && cf.value) {
        cf.value = '[REDACTED]';
      }
    }
  }

  return redacted;
}

// Use when logging API responses
console.log('[clickup] task fetched:', JSON.stringify(redactClickUpResponse(task)));

Data Export for GDPR/CCPA

async function exportUserClickUpData(userId: number, teamId: string) {
  // 1. Get user profile
  const user = await clickupRequest('/user');

  // 2. Get tasks assigned to user across workspace
  const tasks = await clickupRequest(
    `/team/${teamId}/task?assignees[]=${userId}&include_closed=true`
  );

  // 3. Get time entries by user
  const timeEntries = await clickupRequest(
    `/team/${teamId}/time_entries?assignee=${userId}`
  );

  return {
    exportedAt: new Date().toISOString(),
    source: 'ClickUp API v2',
    userData: {
      id: user.user.id,
      username: user.user.username,
      email: user.user.email,
    },
    tasks: tasks.tasks.map((t: any) => ({
      id: t.id,
      name: t.name,
      status: t.status.status,
      url: t.url,
    })),
    timeEntries: timeEntries.data?.map((e: any) => ({
      id: e.id,
      duration: e.duration,
      description: e.description,
      task_id: e.task?.id,
    })) ?? [],
  };
}

Data Retention

// Track ClickUp API data locally with retention policies
interface RetentionPolicy {
  dataType: string;
  retentionDays: number;
  reason: string;
}

const RETENTION_POLICIES: RetentionPolicy[] = [
  { dataType: 'api_request_logs', retentionDays: 30, reason: 'Debugging' },
  { dataType: 'webhook_events', retentionDays: 90, reason: 'Audit trail' },
  { dataType: 'cached_tasks', retentionDays: 1, reason: 'Performance' },
  { dataType: 'time_entries', retentionDays: 365, reason: 'Billing' },
  { dataType: 'audit_logs', retentionDays: 2555, reason: 'Compliance (7 years)' },
];

async function enforceRetention(db: any) {
  for (const policy of RETENTION_POLICIES) {
    const cutoff = new Date();
    cutoff.setDate(cutoff.getDate() - policy.retentionDays);
    await db.collection(policy.dataType).deleteMany({
      createdAt: { $lt: cutoff },
    });
  }
}

Error Handling

Issue	Cause	Solution
PII in logs	Missing redaction	Wrap all logging with redactClickUpResponse
GDPR export incomplete	Pagination not handled	Use async generator for full export
Retention job fails	DB connection	Add retry logic to cron job
Custom field PII missed	New field types	Re-scan fields via /list/{id}/field

Prerequisites

• Approved data inventory, purpose, classification, and named data owner
• Documented authorized destinations, access controls, retention, and deletion path
• Redaction tests for task/comment/custom-field and webhook data

Instructions

Minimize collection, classify fields before storage, enforce destination and retention controls, and verify deletion/export behavior across every synced system. Treat task text, comments, assignees, custom fields, and attachments as potentially sensitive; use redacted diagnostics and obtain legal/privacy review when the use case or jurisdiction requires it.

Output

Maintain a data-handling record with source, purpose, classification, allowed uses/destinations, access owner, retention/deletion results, request status, and audit reference. Do not place personal task data, tokens, or raw API responses in the record.

Examples

Before syncing a new custom field, classify it, add it to the redaction and retention tests, and verify it is excluded from general logs. For a deletion request, enumerate ClickUp and downstream copies, remove or suppress them via the approved route, and record redacted completion evidence.
