Check a single number against the carrier deactivation (churn) feed
Returns whether the given E.164 number was deactivated by the subscriber’s carrier (and should be scrubbed from the recipient list). Supply last_seen (the date you last validated the number) to ignore deactivations that predate the current subscriber relationship. Read-only — does not perform a send.
Gated behind organizations.settings.deactivation_scrub_enabled. When OFF, responses are HTTP 403 DEACTIVATION_SCRUB_NOT_ENABLED. When ON, feed_synced reports whether a carrier deactivation snapshot is loaded; until one is configured every verdict is no_data.

Headers
Sandbox opt-in for Clerk-session-authenticated requests. Set to true to route the call through the test-mode pipeline: no real provider delivery, no credits deducted, response meta.test_mode: true. Ignored for live API keys (dv_live_sk_*) — server-to-server clients must use a test-prefixed key (dv_test_sk_*) to exercise sandbox. Test-prefixed keys unconditionally enable sandbox regardless of this header.
true, false Query Parameters
E.164 number to scrub (e.g. +14155551234).
ISO calendar date (YYYY-MM-DD) you last validated the number. Deactivations before this date are ignored.
Response
Successful response.
