Number ownership needs confirmation
A monitored number hosted with another provider changed carrier, or its periodic ownership re-verification is due. Confirm ownership before confirm_by with POST /enterprises/{enterprise_id}/reputation/numbers/{phone_number}/ownership_confirm.
Sent to the enterprise's ownership webhook URL (PATCH /enterprises/{enterprise_id}/reputation/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
Unix timestamp (seconds since epoch) of when the webhook was sent - compatible with webhook-timestamp
Ed25519 signature of the payload - compatible with webhook-signature

Changes
Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
