Kapso Platform lets your customers connect their own WhatsApp Business accounts without sharing credentials.

​
Use cases

Perfect when you need your customers to use their own WhatsApp:
  • CRM platforms - Let each client connect their WhatsApp for customer communication
  • Appointment booking - Clinics and salons send reminders from their own number
  • E-commerce tools - Stores send order updates using their WhatsApp Business
  • Marketing platforms - Agencies manage multiple client WhatsApp accounts
  • Support software - Each company provides support through their WhatsApp
The key: your customers maintain ownership of their WhatsApp while you handle the automation.

​
Quick example

// Your customer "Acme Corp" wants to use WhatsApp
const customer = await createCustomer({ name: 'Acme Corp' });
const setupLink = await generateSetupLink(customer.id);

// Share the setup link with your customer
console.log(`Setup link: ${setupLink.url}`);
// Example: https://app.kapso.ai/setup/abc123xyz

// After they connect, send messages from their WhatsApp
await sendWhatsAppMessage({
  customer_id: customer.id,
  phone_number: '+1234567890',
  content: 'Order confirmed!'
});
