Connect Kai to any system you use.
Don't see your CRM or tool in our integrations? Use webhooks to send conversation data to any system with an API. A webhook is a digital signal that sends data automatically from one application to another when a specific event occurs. Kai sends real-time HTTP callbacks with full conversation details in JSON format. Setup typically takes 15 minutes, with developer documentation included.
Kai pushes call summaries the moment a conversation ends — no polling, no manual exports.
Point Kai at your endpoint, pick the events you care about, and test with sample payloads.
Works with custom CRMs, internal databases, analytics platforms, or any system with an API endpoint.
how it works
Understanding webhooks
Webhooks turn every important event in Kai into an instant signal your systems can act on — no polling required.
What is a webhook?
A webhook is a digital signal that sends data automatically from one application to another when a specific event occurs. Think of it as a notification system for software: instead of constantly checking for updates, your system receives instant alerts when something important happens.
Reverse API architecture
Webhooks act like a "reverse API" by pushing data to your system instead of waiting for your system to request it. Traditional APIs require you to constantly poll for new data, but webhooks proactively send updates the moment they happen, making your integrations faster and more efficient.
How KaiCalls uses webhooks
KaiCalls uses webhooks to push call summaries instantly after a call ends. The moment a conversation completes, Kai automatically sends the complete call details — including transcript, lead score, customer information, and next steps — directly to your system. No manual exports, no delays, no constant checking for updates.
