What does Kapso do?

Kapso handles WhatsApp onboarding and messaging by combining a simple API, setup links, and webhook-driven automation. You can create customers, generate onboarding links, and send messages from code, while the platform also supports sandbox testing, API logs, message tracking, inbox management, workflows, broadcasts, and agents for day-to-day operations. It's built to let teams move from setup to live messaging quickly, without stitching together separate tools. At scale, Kapso is positioned for WhatsApp infrastructure across products and customer accounts: it says you can ship to 3 billion WhatsApp users and connect in 2 minutes. The platform page shows multi-tenant flows for onboarding thousands of customers, with Acme Corp and TechStart Inc as example accounts. It also includes serverless functions for custom JavaScript, plus integrations with 2,700+ apps and Meta-supported WhatsApp flows. The docs advertise a simple API for creating customers, generating setup links, and sending WhatsApp messages.

Why use Kapso?

  • It shortens WhatsApp setup to a few API calls and a setup link, reducing the integration work needed to get customers live.
  • Its multi-tenant flow lets you onboard thousands of customer accounts without rebuilding WhatsApp infrastructure for each one.
  • Sandbox mode, API logs, and message tracking make it easier to test, debug, and monitor delivery behavior before rollout.
  • Serverless functions let teams run custom JavaScript alongside WhatsApp events, so automation can stay close to the messaging layer.
  • The platform supports Meta-backed embedded signup and branded onboarding, which helps teams keep the customer experience inside their own product.

What are Kapso's use cases?

SaaS teams embed WhatsApp

SaaS product teams who need to embed WhatsApp messaging into their app use Kapso to launch customer messaging fast, using Embedded Signup and Full API Control to connect accounts without a heavy setup. They can then route events through WhatsApp webhooks and Message tracking to confirm delivery and keep onboarding flows moving.

Agencies manage client setups

Agencies who manage WhatsApp setups for multiple client accounts use Kapso to spin up and oversee each client environment, using Multi-tenant Ready and Setup Links to onboard accounts cleanly. Inbox and Usage Tracking help them monitor activity, reduce handoff friction, and keep client messaging organized.

Ops teams centralize messaging

Operations teams who need inboxes, broadcasts, and message tracking in one place use Kapso to handle day-to-day WhatsApp communication, using Inbox and Broadcasts to send updates and respond from a single workspace. Message tracking and Health Monitoring help them catch delivery issues early and keep campaigns reliable.

Automation builders connect agents

Automation builders who want workflows and agents connected to WhatsApp use Kapso to trigger actions from chat events, using Workflows and Agents to automate replies, routing, and follow-ups. WhatsApp webhooks and Integrations with tools like HubSpot or Claude help them turn conversations into repeatable processes.

How does Kapso work?

  1. Generate a setup link in Kapso to start the first WhatsApp connection, then share it with the customer or team member who will connect their number and account.
  2. Let the customer connect through Embedded Signup or Use your own SIM, then confirm the account inside the Inbox and verify the connection is ready.
  3. Configure WhatsApp webhooks and API logs so your app can receive events, inspect requests, and trace message activity while you test the flow in Sandbox mode.
  4. Build automations with Workflows or Agents, then send messages, broadcasts, and follow-ups through the API while Message tracking and Usage Tracking show what is happening.
  5. Monitor Health Monitoring and adjust Integrations as you scale, keeping each connected account organized and ready for ongoing WhatsApp operations.
