  const values = range.getValues();
  
  const API_KEY = 'your_cufinder_api_key';
  const API_URL = 'https://api.cufinder.io/v2/fwe';
  
  // Process each row with LinkedIn URL
  for (let i = 1; i < values.length; i++) {
    const linkedinUrl = values[i][0]; // Column A contains LinkedIn URLs
    
    if (linkedinUrl && linkedinUrl.includes('linkedin.com/in/')) {
      const email = discoverEmail(linkedinUrl, API_KEY, API_URL);
      sheet.getRange(i + 1, 2).setValue(email); // Column B for emails
      
      // Rate limiting
      Utilities.sleep(1000);
    }
  }
}

function discoverEmail(linkedinUrl, apiKey, apiUrl) {
  const payload = {
    'linkedin_url': linkedinUrl
  };
  
  const options = {
    'method': 'POST',
    'headers': {
      'Content-Type': 'application/x-www-form-urlencoded',
      'x-api-key': apiKey
    },
    'payload': Object.keys(payload).map(key => key + '=' + encodeURIComponent(payload[key])).join('&')
  };
  
  try {
    const response = UrlFetchApp.fetch(apiUrl, options);
    const data = JSON.parse(response.getContentText());
    
    if (data.status === 1 && data.data.work_email) {
      return data.data.work_email;
    }
    return 'Email not found';
  } catch (error) {
    return 'Error: ' + error.toString();
  }
}

This script provides foundation functionality that can be enhanced with error handling, progress tracking, and result validation. The person enrichment API offers additional profile data that can be integrated into comprehensive prospect research workflows.

Managing Data Quality and Validation

Effective Google Sheets integration includes robust data quality controls that ensure discovered emails meet deliverability standards and organizational requirements. Implement validation rules that check email format, domain authenticity, and confidence levels before accepting results.

function validateDiscoveredEmail(email, confidenceLevel) {
  // Basic format validation
  const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
  if (!emailRegex.test(email)) {
    return {valid: false, reason: 'Invalid email format'};
  }
  
  // Confidence threshold check
  if (confidenceLevel < 85) {
    return {valid: false, reason: 'Low confidence score'};
  }
  
  // Generic email detection
  const genericPatterns = ['info@', 'contact@', 'support@', 'sales@'];
  const isGeneric = genericPatterns.some(pattern => email.toLowerCase().includes(pattern));
  
  return {
    valid: true,
    isGeneric: isGeneric,
    quality: isGeneric ? 'generic' : 'personal'
  };
}

Quality validation prevents low-quality contacts from entering your outreach campaigns while maintaining high deliverability rates that protect sender reputation. The data enrichment APIs demonstrate comprehensive validation approaches that maintain data integrity at scale.

Implement duplicate detection logic that identifies and consolidates multiple entries for the same prospect, preventing redundant outreach and maintaining clean contact databases.

Handling Rate Limits and Performance Optimization

Google Sheets integrations must respect API rate limits while maintaining reasonable processing speeds for large datasets. Implement intelligent batching that processes prospects in groups, includes appropriate delays between requests, and provides progress feedback to users.

function processLinkedInUrlsBatch(urls, batchSize = 10, delayMs = 2000) {
  const results = [];
  
  for (let i = 0; i < urls.length; i += batchSize) {
    const batch = urls.slice(i, i + batchSize);
    
    // Process current batch
    const batchResults = batch.map(url => {
      return discoverEmail(url, API_KEY, API_URL);
    });
    
    results.push(...batchResults);
    
    // Update progress in spreadsheet
    const progress = Math.round((i + batch.length) / urls.length * 100);
    SpreadsheetApp.getActiveSheet().getRange('Z1').setValue(`Processing: ${progress}%`);
    
    // Rate limiting delay
    if (i + batchSize < urls.length) {
      Utilities.sleep(delayMs);
    }
  }
  
  return results;
}

Performance optimization ensures reliable processing of large prospect lists without overwhelming API services or exceeding Google Apps Script execution time limits. The company enrichment API showcases enterprise-grade infrastructure designed to handle demanding integration workloads efficiently.

Caching mechanisms reduce redundant API calls by storing recent results and checking for existing data before making new requests, improving both performance and cost efficiency.

function enrichProspectProfile(linkedinUrl) {
  const emailData = discoverEmail(linkedinUrl, API_KEY, EMAIL_API_URL);
  const profileData = enrichLinkedInProfile(linkedinUrl, API_KEY, PROFILE_API_URL);
  const companyData = getCompanyInfo(profileData.company_name, API_KEY, COMPANY_API_URL);
  
  return {
    email: emailData,
    profile: profileData,
    company: companyData,
    enrichment_date: new Date().toISOString()
  };
}

Multi-dimensional enrichment creates valuable prospect intelligence that enables personalized outreach based on comprehensive understanding of both individual contacts and their organizational context.

  let totalProcessed = 0;
  let emailsFound = 0;
  let errors = 0;
  
  for (let i = 1; i < data.length; i++) {
    if (data[i][0]) { // LinkedIn URL exists
      totalProcessed++;
      
      if (data[i][1] && !data[i][1].includes('Error')) { // Email found
        emailsFound++;
      } else if (data[i][1] && data[i][1].includes('Error')) {
        errors++;
      }
    }
  }
  
  const successRate = totalProcessed > 0 ? (emailsFound / totalProcessed * 100).toFixed(2) : 0;
  const errorRate = totalProcessed > 0 ? (errors / totalProcessed * 100).toFixed(2) : 0;
  
  // Update dashboard
  const dashboard = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Dashboard');
  dashboard.getRange('B2').setValue(totalProcessed);
  dashboard.getRange('B3').setValue(emailsFound);
  dashboard.getRange('B4').setValue(successRate + '%');
  dashboard.getRange('B5').setValue(errorRate + '%');
}

Analytics provide insights that optimize discovery workflows and identify opportunities for improvement in prospect targeting and data quality management. The company lookalikes finder API demonstrates how data-driven insights enhance targeting effectiveness across entire prospect databases.

Implementing Security and Compliance Controls

Google Sheets integrations handling personal contact information must implement appropriate security measures and compliance controls that protect sensitive data while maintaining operational efficiency. Store API credentials securely, implement access controls, and maintain audit trails of all processing activities.

function secureEmailDiscovery(linkedinUrl) {
  // Get API key from secure properties
  const apiKey = PropertiesService.getScriptProperties().getProperty('CUFINDER_API_KEY');
  
  if (!apiKey) {
    throw new Error('API key not configured');
  }
  
  // Log request for audit trail
  console.log(`Processing LinkedIn URL: ${linkedinUrl} at ${new Date().toISOString()}`);
  
  // Process with error handling
  try {
    const result = discoverEmail(linkedinUrl, apiKey, API_URL);
    
    // Log success
    console.log(`Email discovery completed for ${linkedinUrl}`);
    
    return result;
  } catch (error) {
    console.error(`Error processing ${linkedinUrl}: ${error.message}`);
    return `Error: ${error.message}`;
  }
}

Compliance with GDPR, CCPA, and industry-specific regulations requires careful data handling practices and clear documentation of processing activities. The domain to company name API demonstrates how professional data services maintain compliance standards automatically.
