Use Cases

Import Contacts from CSV

javascript

const importContactsFromCSV = async (csvData) => {
  const contacts = parseCSV(csvData); // Your CSV parser

  for (const contact of contacts) {
    try {
      await createContact({
        phone: contact.phone,
        email: contact.email,
        name: contact.name,
        tags: ['imported'],
        custom_fields: {
          import_date: new Date().toISOString(),
          source: 'csv_import'
        }
      });
    } catch (error) {
      console.error(`Failed to import ${contact.phone}:`, error);
    }
  }
};

Segment Contacts by Tags

javascript

const getContactsBySegment = async (segment) => {
  const response = await listContacts({ tags: segment });
  return response.data.contacts;
};

// Get VIP customers
const vipCustomers = await getContactsBySegment('vip');

// Get recent signups
const newUsers = await getContactsBySegment('new_user');

Sync Contacts with CRM

javascript

const syncWithCRM = async () => {
  // Get all contacts from YeboLink
  const yeboContacts = await listContacts({ limit: 100 });

  for (const contact of yeboContacts.data.contacts) {
    // Check if exists in CRM
    const crmContact = await crm.findByPhone(contact.phone);

    if (crmContact) {
      // Update YeboLink with CRM data
      await updateContact(contact.id, {
        custom_fields: {
          crm_id: crmContact.id,
          last_sync: new Date().toISOString()
        }
      });
    }
  }
};

Send to Tagged Contacts

javascript

const sendToSegment = async (tags, message) => {
  const contacts = await listContacts({ tags });

  const recipients = contacts.data.contacts.map(contact => ({
    to: contact.phone,
    name: contact.name,
    ...contact.custom_fields
  }));

  return await sendBulkSMS(message, recipients);
};

// Send promotion to VIP customers
await sendToSegment('vip', 'Hi {{name}}, exclusive VIP offer inside!');

Best Practices

1. Use Tags for Organization

Organize contacts with meaningful tags:

javascript

const tags = {
  lifecycle: ['lead', 'customer', 'churned'],
  value: ['vip', 'premium', 'standard'],
  engagement: ['active', 'inactive', 'bounced'],
  source: ['website', 'referral', 'event']
};

2. Store Important Data in Custom Fields

javascript

await createContact({
  phone: '+1234567890',
  name: 'John Doe',
  custom_fields: {
    customer_id: '12345',
    lifetime_value: 5000,
    last_purchase: '2025-11-01',
    preferred_channel: 'sms',
    timezone: 'America/New_York'
  }
});

3. Keep Contacts Up to Date

javascript

const updateContactAfterPurchase = async (contactId, orderData) => {
  const contact = await getContact(contactId);

  await updateContact(contactId, {
    tags: [...contact.data.contact.tags, 'customer'],
    custom_fields: {
      ...contact.data.contact.custom_fields,
      last_order: orderData.id,
      last_purchase: new Date().toISOString(),
      total_orders: (contact.data.contact.custom_fields.total_orders || 0) + 1
    }
  });
};

4. Handle Duplicates

javascript

const findOrCreateContact = async (phone, contactData) => {
  // Search for existing contact
  const existing = await listContacts({ search: phone });

  if (existing.data.contacts.length > 0) {
    // Update existing contact
    return await updateContact(existing.data.contacts[0].id, contactData);
  } else {
    // Create new contact
    return await createContact({ phone, ...contactData });
  }
};
