# Webhooks

> Receive real-time HTTP notifications when events occur in your application

Webhooks let your application receive real-time HTTP `POST` notifications whenever something happens in Chirp — an inbound message, a status update, a template approval, a phone-number quality change, a call ending, and many more.

## Per-application configuration

Each [application](/concepts/applications) has its own webhook configuration:

* Different webhook URLs per application
* Independent event subscriptions per application
* Isolated delivery and retry logic

## Available events

Chirp emits webhooks across every channel and resource type. The full catalog with payload schemas, trigger conditions, and delivery cadence lives in [Webhook Event Reference](/api_reference/webhooks/events).

At a glance:

* **SMS messages** — inbound, sent, delivered, failed
* **WhatsApp messages** — received, sent, delivered, read, failed (incl. enriched failure details)
* **WhatsApp templates** — created, updated, deleted, connected
* **WhatsApp contacts** — created, updated, deleted, preferences updated, CTWA conversion events
* **WhatsApp groups** — created, deleted, suspended, participants added/removed/left, join requests, settings updated
* **WhatsApp account & WABA** — connected, disconnected, alerts, policy reviews, capability changes
* **WhatsApp phone numbers** — name updated, quality changed, security events, deregistered
* **Partner & payment** — partner solutions, payment configurations
* **Calling** — initiated, ringing, answered, completed, failed, no\_answer, participant join/leave, recording completed, voicemail received

## Webhook configuration

When creating a webhook, you specify:

**URL** — the publicly accessible HTTPS endpoint where payloads are delivered.

**Events** — the array of event types you want to subscribe to. Subscribe only to what you need; new events are opt-in.

**Headers** *(optional)* — custom HTTP headers added to each request, useful for authenticating the request as coming from Chirp or routing to specific handlers.
