# SMS Webhooks Introduction (v1)

> Receive SMS webhook events from Hypersender: message sent, delivered, failed, received, and scheduled events, plus phone heartbeats. (v1 API)

## Hypersender SMS Webhooks

The Hypersender SMS API offers a webhook-based integration that delivers real-time, event-driven notifications. This allows developers to monitor their connected phones (sms app) or respond to specific events.

* **Monitor Message Status**: Provides real-time updates on the status of sent messages, such as when the message is queued to be sent or has been successfully delivered.

* **Receive Incoming Messages**: Get notified when a new message is received on the connected phone.

* **Monitor Connected Phone**: Receive periodic heartbeats from your connected phone to ensure the connection is active and act when the phone is offline.
