Understanding Webhooks

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.

What is a webhook in answering services?

A webhook is a digital signal that sends data automatically from one application to another when a specific event occurs.

This eliminates manual data entry and ensures immediate availability of call information in your workflows.

How do I verify webhooks are from Kai?

Each webhook includes an HMAC signature header. Use your webhook secret to verify the signature matches the payload.

What happens if my endpoint is down?

Kai automatically retries failed webhooks up to 5 times with exponential backoff. You can view retry history in the dashboard.
