Customer-owned accounts
Connect each tenant's own WhatsApp account and phone number to your product.
Automate WhatsApp for your customers
Kapso is a BSP that lets you connect your customers' WhatsApp accounts to your SaaS product. Skip months of Meta API integration and ship this week.
Ship WhatsApp inside your SaaS product
Connect each customer's WhatsApp account while their Meta Business Portfolio and WhatsApp Business Account remain theirs. Kapso provides the infrastructure around the connection so your product can own the customer experience.
Connection links
Create a hosted, expiring setup link for each customer. They complete Meta's official embedded signup.
Server-side integration
Use the Platform API from your backend and keep project API keys out of customer-facing browser code.
A clean four-step onboarding flow
Onboard a customer and send your first message in four steps.
Create a customer
Represent each tenant or client in your Kapso project with a stable external customer ID.
Generate a setup link
Choose the connection and billing policy, then send the customer a hosted onboarding URL.
Customer connects
They complete Meta's embedded signup, and you get a webhook when their number connects.
Send and automate
Use the WhatsApp API and webhooks to send messages, receive events, and sync connection status.
Everything you need to run customer WhatsApp
Build the integration on server-side APIs, then run customer conversations with webhooks, inbox tooling, workflows, and observability.
APIs and webhooks
Create customers and setup links from your backend, send messages, and receive inbound and delivery events.
Conversations and inbox
Keep customer conversations available for automation, support, and human handoff when it is needed.
Templates and workflows
Use templates, broadcasts, WhatsApp Flows, and serverless functions to build repeatable experiences.
Phone infrastructure
Support customer-owned numbers and, where available, speed up onboarding with a Kapso number.
Health and delivery
Track phone health, message delivery, usage, and webhook activity across every connected customer.
Kapso WhatsApp MCP
Give developers and agents a direct way to inspect and work with WhatsApp.
Choose how billing fits your product
Offer customer-managed Meta billing or, when eligible, let customers skip Meta billing setup with Kapso-managed billing. Keep pricing and the billing experience aligned with your product.
Operate every customer number from one place
Give your team one view of health, messages, usage, connection status, and billing state across customer accounts. Kapso's logs, webhooks, inbox, and workflows help you investigate delivery issues and keep production WhatsApp reliable.
