Kapso

Agent-enablingFreemium

Kapso connects agents to WhatsApp through Meta-compatible APIs, webhooks, a TypeScript SDK, and a hosted project MCP endpoint. Builders can use it for support replies, onboarding flows, reminders, template messages, and shared-inbox handoff while keeping conversation history queryable through Kapso storage.

Overview

About Kapso

Kapso is a developer-focused layer on top of the WhatsApp Cloud API. Its current docs center on a Meta-compatible TypeScript SDK plus Kapso storage and query extensions for messages, conversations, contacts, flows, templates, and call logs.

Features

TypeScript SDK that mirrors Meta’s WhatsApp Cloud API surface
Send text, media, location, contacts, reactions, templates, and interactive flow messages
Conversation, message-history, contact, and call-log APIs when routed through the Kapso proxy
WhatsApp Flows authoring, publishing, previewing, and event handling helpers
Webhook normalization, signature verification, and extra Kapso response fields for stored history

So agents can…

Run two-way WhatsApp support or outreach workflows with a proper message history layer
Trigger templated onboarding, reminders, and transactional notifications inside WhatsApp
Hand off from message parsing to structured workflow execution using flows, contacts, and conversation metadata

Listing decision

Why Kapso is listed

Kapso is a programmable WhatsApp platform used by agents, backend systems, and human teams; its APIs and communication infrastructure enable agent workflows without making Kapso itself the autonomous actor.

Before you choose

Fit and limitations

Best for

Products and agent workflows that need two-way WhatsApp messaging, stored conversation history, templates, flows, webhooks, or a shared operational inbox.

Known limitations

Meta message charges are billed separately from Kapso plans. The included sandbox is for testing only and omits templates, WhatsApp synchronization, and multiple-recipient use.
