# Conference Floor Changed

`POST conferenceFloorChanged` (webhook)

This webhook uses Telnyx headers (telnyx-timestamp, telnyx-signature-ed25519) that are compatible with Standard Webhooks specification for SDK generation. Custom validation logic can map these to standard webhook-timestamp and webhook-signature equivalents. See https://github.com/standard-webhooks/standard-webhooks for details.

## Headers

- `telnyx-timestamp` integer, required — Unix timestamp for replay attack prevention
- `telnyx-signature-ed25519` string, required — Ed25519 signature of timestamp|payload for verification

## Payload

- ConferenceFloorChangedEvent
  - `event_type` 'conference.floor.changed' — The type of event being delivered.
  - `id` string, uuid — Identifies the type of resource.
  - `payload` object
    - `call_control_id` string — Call Control ID of the new speaker.
    - `call_leg_id` string — Call Leg ID of the new speaker.

## Acknowledgement `200`

The server must return an HTTP 200, otherwise we will reattempt delivery at the failover webhook URL.
