# Webhooks

The Sinch Voice platform delivers real-time call event notifications to a configured webhook URL via HTTP POST requests.
The receiving endpoint responds with [SVAML commands](/docs/voice/api-reference/svaml) that control the ongoing call flow.



## Call webhook

 - [POST call.webhook](https://developers.sinch.com/docs/voice-2.0/api-reference/voice/webhooks/callwebhook.md): Receives webhook notifications for call events from the Voice Platform.

Security Note: Webhook requests are authenticated using the Authorization header with a Bearer token. The RFC 9421 webhook signing headers (Content-Digest, Signature-Input, Signature) are not yet supported. Customers should validate webhook authenticity by verifying the Bearer token in the Authorization header.
