const result = await sdk.getLeadsForYesterday();

if (result.success) {
  console.log(`Found ${result.leads.length} leads`);
  console.log(`Downloaded to: ${result.downloadPath}`);
} else {
  console.error('Error:', result.error);
}

import { IndiaMartSDK } from 'indiamart-lms-sdk';

const sdk = new IndiaMartSDK(process.env.INDIAMART_CRM_KEY);

// Fetch leads for yesterday
const result = await sdk.getLeadsForYesterday();
if (result.success) {
  console.log(`Found ${result.leads.length} leads`);
  console.log(`Downloaded to: ${result.downloadPath}`);
}

Date Range Queries

// Fetch leads for a specific date range
const result = await sdk.getLeadsForDateRange('2024-01-01', '2024-01-07');
if (result.success) {
  console.log(`Found ${result.leads.length} leads`);
}

try {
  const result = await sdk.getLeadsForYesterday();
  if (!result.success) {
    console.error('API Error:', result.error);
    return;
  }
  // Process leads
} catch (error) {
  console.error('Unexpected error:', error.message);
}

// Check SDK health
const health = await sdk.getHealthStatus();
console.log('SDK Health:', health.status);

// Get performance statistics
const cacheStats = sdk.getCacheStats();
const apiStats = sdk.getAPIStats();

console.log('Cache Hit Rate:', `${cacheStats.hitRate}%`);
console.log('API Success Rate:', `${(apiStats.successfulCalls / apiStats.totalCalls * 100).toFixed(1)}%`);

Cache Management

// Monitor cache performance
const cacheStats = sdk.getCacheStats();
if (cacheStats.hitRate < 50) {
  console.warn('Low cache hit rate:', cacheStats.hitRate);
}

// Clear cache
await sdk.clearCache();

// Clear specific cache pattern
await sdk.clearCache('leads:.*');
