# Create a webhook

`POST /v1/webhooks`

Creates a new webhook endpoint. When events occur (e.g. feedback_record.created),
the Hub POSTs a signed payload to the webhook URL. If signing_key is omitted,
a key is auto-generated (Standard Webhooks format, whsec_...).
tenant_id is required; webhooks only receive events from that exact tenant.
See WebhookDeliveryPayload for the payload structure sent to your URL.

## Request body

- CreateWebhookInputBody
  - `url` string, uri, required — URL to receive webhook POSTs. Must be an HTTP or HTTPS URL. NULL bytes not allowed.
  - `signing_key` string — Optional. If omitted, a key is auto-generated (whsec_...). Used to sign payloads (Standard Webhooks). When provided, max 255 characters; NULL bytes not allowed.
  - `enabled` boolean — Whether the webhook is active (default true)
  - `tenant_id` string, required — Tenant/organization identifier. Required for webhook isolation; NULL bytes not allowed.
  - `event_types` WebhookEventType[] — Event types this webhook subscribes to. Each value must be one of WebhookEventType. If empty, the webhook receives all event types.
