To get started with Kapso, you’ll need:
  • A WhatsApp number connected to Kapso. On the free plan we give you a pre-verified number at no cost, so you can start without buying one or waiting on SMS verification
  • A Kapso API key
Then you’ll be ready to build either way of using WhatsApp:
  • For your team: connect your own number, handle conversations in a shared inbox, send broadcasts, and automate your operations
  • For your customers: onboard them with their own numbers through setup links, and message from each of them
