        'x-api-key': 'your_api_key_here',
      },
    },
  );

  const contacts = await response.json();

  // Group by platform
  const byChannel = contacts.reduce((acc, contact) => {
    const channel = contact.platform || 'unknown';
    if (!acc[channel]) acc[channel] = [];
    acc[channel].push(contact);
    return acc;
  }, {});

  console.log('Contacts by channel:', {
    whatsapp: byChannel.whatsapp?.length || 0,
    instagram: byChannel.instagram?.length || 0,
    webchat: byChannel.webchat?.length || 0,
  });

  return byChannel;
};

3. Find Unattended Contacts

  // Filter unattended
  const unattended = contacts.filter(
    (c) => c.chat_status === 'UNATTENDED' && !c.is_chat_read,
  );

  console.log(`${unattended.length} unattended contacts need attention`);

  return unattended;
};

4. Re-engagement Campaign Data

const getContactsForReengagement = async () => {
  // Get contacts from 30-60 days ago (active before but not recently)
  const recent30 = await fetch(
    'https://api.vambe.ai/api/public/contacts?days=30',
    {
      headers: { 'x-api-key': 'your_api_key_here' },
    },
  ).then((r) => r.json());

    'https://api.vambe.ai/api/public/contacts?days=60',
    {
      headers: { 'x-api-key': 'your_api_key_here' },
    },
  ).then((r) => r.json());

  // Contacts in 60 days but not in 30 days
  const recent30Ids = new Set(recent30.map((c) => c.id));
  const reengageTargets = recent60.filter((c) => !recent30Ids.has(c.id));

  console.log(`${reengageTargets.length} contacts for re-engagement campaign`);

  return reengageTargets;
};

5. Export to External CRM

const exportRecentContactsToCRM = async (days) => {
  const response = await fetch(
    `https://api.vambe.ai/api/public/contacts?days=${days}`,
    {
      headers: {
        'x-api-key': 'your_api_key_here',
      },
    },
  );

  const contacts = await response.json();

  // Export to external CRM

    await fetch('https://external-crm.com/api/contacts/sync', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        Authorization: 'Bearer crm_token',
      },
      body: JSON.stringify({
        external_id: contact.id,
        name: contact.name,
        phone: contact.phone,
        email: contact.email,
        platform: contact.platform,
        last_activity: contact.last_message_at,
        status: contact.chat_status,
      }),
    });
  }

  console.log(`Exported ${contacts.length} contacts to CRM`);
};

6. Activity Dashboard

const buildActivityDashboard = async () => {
  const periods = [
    { label: 'Today', days: 1 },
    { label: 'Last 7 days', days: 7 },
    { label: 'Last 30 days', days: 30 },
    { label: 'Last 90 days', days: 90 },
  ];

  const dashboard = {};

  for (const period of periods) {
    const response = await fetch(
      `https://api.vambe.ai/api/public/contacts?days=${period.days}`,
      {
        headers: {
          'x-api-key': 'your_api_key_here',
        },
      },
    );

    const contacts = await response.json();

    dashboard[period.label] = {
      total: contacts.length,
      unattended: contacts.filter((c) => c.chat_status === 'UNATTENDED').length,
      attended: contacts.filter((c) => c.chat_status === 'ATTENDED').length,
      byChannel: contacts.reduce((acc, c) => {
        acc[c.platform] = (acc[c.platform] || 0) + 1;
        return acc;
      }, {}),
    };
  }

  console.log('Activity Dashboard:', dashboard);
  return dashboard;
};

Days Parameter

The days parameter filters contacts where last_message_at is within the specified number of days from now:

Days Value	Description	Use Case
`1`	Last 24 hours	Today’s activity
`7`	Last week	Weekly engagement report
`30`	Last month	Monthly active contacts
`90`	Last quarter	Quarterly analysis
`180`	Last 6 months	Semi-annual review
`365`	Last year (maximum allowed)	Annual customer base analysis

Response Ordering

Contacts are returned ordered by last_message_at in descending order (most recent first).

Cross-Channel Support

This endpoint returns contacts from all channels:

Platform	Description
`whatsapp`	WhatsApp Business API
`web-whatsapp`	WhatsApp Web (QR)
`instagram`	Instagram Direct Messages
`webchat`	Web chat widget
`sms`	SMS messages
`messenger`	Facebook Messenger
`tiktok`	TikTok Direct Messages
`voice`	Voice calls
`playground`	Test/playground channel

Error Responses

Status Code	Description
400	Bad Request - Invalid days parameter (must be 1-365)
401	Unauthorized - Invalid or missing API key
500	Internal Server Error - Something went wrong

Important Notes

Days Range: Must be between 1 and 365 days
Null Values: Some fields like email or phone may be null
Performance: Response time increases with larger days values
All Channels: Unlike the deprecated WhatsApp-specific endpoint, this returns contacts from ALL channels
Contact Count: No pagination - returns all contacts matching the criteria

Performance Considerations

Cache Results: Consider caching responses for frequently used days values
Large Datasets: For days values > 90, expect larger response sizes
Rate Limiting: Be mindful of rate limits when making frequent requests

Comparison with Deprecated Endpoint

Feature	New Endpoint (This)	Deprecated Endpoint
Path	`/api/public/contacts`	`/api/public/whatsapp/contact/contacts`
Channels	All channels	WhatsApp only
Response	AI Contact objects	WhatsApp Contact objects
Ordering	By last_message_at DESC	Not specified
Future Support	✅ Active development	❌ Deprecated

GET /api/public/contact//info - Get detailed contact info
POST /api/public/customer/upsert/info - Create or update contact
POST /api/public/contact//update-metadata - Update contact metadata

Best Practices

1. Choose Appropriate Days Range

// Good: Specific use case
const getWeeklyActive = () => fetch('...?days=7');
const getMonthlyActive = () => fetch('...?days=30');

// Avoid: Unnecessarily large range
const getAll = () => fetch('...?days=365'); // Only if you need a full year

2. Handle Empty Results

const contacts = await fetch('...?days=7').then((r) => r.json());

if (contacts.length === 0) {
  console.log('No contacts in the last 7 days');
} else {
  console.log(`Found ${contacts.length} active contacts`);
}

3. Filter on Client Side

const contacts = await fetch('...?days=30').then((r) => r.json());

// Filter by platform
const whatsappContacts = contacts.filter((c) => c.platform === 'whatsapp');

// Filter by status
const unread = contacts.filter((c) => !c.is_chat_read);

// Filter by date range
const thisWeek = contacts.filter((c) => {
  const msgDate = new Date(c.last_message_at);
  const sevenDaysAgo = new Date(Date.now() - 7 * 24 * 60 * 60 * 1000);
  return msgDate > sevenDaysAgo;
});
