# Call failed event

`POST call.failed` (webhook)

Fired when a call setup or in-progress call fails (Meta rejected the
connect, Telnyx returned an error, etc.). Payload carries the
upstream error code and message.

## Payload

- WebhookPayloadCallFailed — Webhook payload for the `call.failed` event. Fired when a call setup or in-progress call fails.
  - `id` string, required
  - `event` 'call.failed', required
  - `call` object, required
    - `id` string
    - `metaCallId` string, nullable
    - `accountId` string
    - `phoneNumberId` string
    - `direction` 'inbound' | 'outbound'
    - `from` string
    - `to` string
    - `failedAt` string, date-time
    - `error` object
      - `code` integer
      - `message` string
  - `account` InboxWebhookAccount, required — The account context included in inbox webhook payloads.
    - `id` string, required — Social account ID
    - `accountId` string — Social account ID (same value as id). Canonical field so consumers can filter every webhook event on one field (e.g. route staging vs production by account). id is kept for backward compatibility.
    - `profileId` string — Zernio profile (workspace) ID this account belongs to. Use it to route or filter inbox webhooks by workspace. This is the profile ID only, not its name (resolve the name via the API with this ID). Optional; omitted on the shared WhatsApp sandbox account and when the account has no resolvable profile.
    - `platform` string, required
    - `username` string, required
    - `displayName` string
  - `timestamp` string, date-time, required — UTC time at which Zernio generated this event (set once when the event payload is built, before delivery is queued). Retries and redeliveries keep the original value, so it reflects the event, not the delivery attempt.
