A webhook is an HTTP callback that delivers real-time notifications when events occur. Voice AI platforms use webhooks to notify external systems about call events, enabling integrations and automated workflows.
How do webhooks work?
You configure an endpoint URL to receive notifications. When specified events occur (call started, call ended, action completed), the platform sends an HTTP POST request to your endpoint with event data. Your system processes the notification and can take appropriate action.
Why do webhooks matter?
Webhooks enable real-time integration without polling. External systems can react immediately to call events: updating CRM records when calls end, triggering workflows when certain intents are detected, or alerting staff when escalations occur. They are the connective tissue between voice AI and business systems.
Webhook in practice
A company configures webhooks to notify their CRM when AI calls complete. Each call end triggers a webhook containing the summary, outcome, and any captured information. The CRM automatically creates or updates the contact record, logs the interaction, and assigns follow-up tasks. No manual data entry required.
