# 10DLC status callback

assignment orders, and number assignments in real time.

Configure `status_callback_url` when
[creating a brand](/docs/apis/rest/campaign-registry/brands/create-brand),
[creating a campaign](/docs/apis/rest/campaign-registry/campaigns/create-campaign), or
[creating a number assignment order](/docs/apis/rest/campaign-registry/phone-number-assignments/create-order).

Status callbacks are advisory, best-effort notifications — delivery can be delayed or fail silently, so don't gate time-critical actions on receiving one. See [Status callback reliability](/docs/platform/webhooks#status-callback-reliability).
