What does Kapso do?

Kapso is a developer platform that lets you add official WhatsApp messaging to your product in minutes. It provides an API, SDK, and tools to send and receive messages, manage conversations, and automate workflows — all backed by Meta's official WhatsApp Business API. Whether you're building a customer support chatbot, a sales funnel, or a notification system, Kapso handles the complex Meta integration so you can focus on your app.

Getting started is fast. You can get a US phone number instantly without a SIM card, use your own number with one-time verification, or keep your existing WhatsApp Business app. Kapso offers a sandbox mode for testing, real-time webhooks for message delivery tracking, and detailed API logs for debugging. Beyond basic messaging, Kapso includes a visual workflow builder that connects to 2,700+ apps, AI agents for automated conversations, and serverless functions to process webhooks. You can also build mini-apps inside WhatsApp using WhatsApp Flows.

Kapso is designed for developers, product teams, and businesses that need reliable WhatsApp integration at scale. Use cases include automating customer support, sending order updates, capturing leads, broadcasting campaigns, and building conversational experiences. With 2,000 free messages per month and a simple API, Kapso lowers the barrier for any developer to reach WhatsApp's 3 billion users.
