# Retell Webhook

`POST /retell_webhook`

Webhook for Retell voice-agent call events (signature-collection pilot).

The body is taken raw because the HMAC in the X-Retell-Signature header
covers the exact bytes sent, which can't be re-derived from a parsed payload.

## Headers

- `X-Retell-Signature` string, nullable

## Response `200`

Successful Response

- unknown

## Other responses

- `422` — Validation Error
