# sms.registration.action_required

An SMS registration is waiting on its owner; `reason` says why.

### Reasons

- `changes_requested`: answer `message` via `POST /v1/sms/registrations/{id}/respond`.
- `otp_required`: submit the texted code via `POST /v1/sms/registrations/{id}/verify-otp`; no `message`.
- `carrier_info_required`: expires after 7 days.

### When it fires

Fires once per new request and once per OTP or carrier request, not on follow-up messages. A carrier rejection alone does not fire it.




**Payload for `sms.registration.action_required`:**

- **test** `boolean`: Always true when present: only a sample sent by POST /v1/webhooks/test with an event carries it. Real deliveries never do.
- **id** `string`: Stable webhook event ID: the dedupe key, also sent as the X-Zernio-Event-Id header and identical on every retry and redelivery. It identifies the event only, never an account or other resource.
- **profiles**: `WebhookProfiles` - See schema definition
- **event** `string`: No description - one of: sms.registration.action_required
- **timestamp** `string` (date-time): 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.
- **registration** `object`: 
  - **id** `string`: No description
  - **type** `string`: No description - one of: standard_10dlc, sole_prop_10dlc, toll_free
  - **displayName** `string,null`: No description
  - **status** `string`: Registration status when the event fired (changes_requested, pending or rejected).
  - **profileId** `string`: No description
- **reason** `string`: No description - one of: changes_requested, otp_required, carrier_info_required
- **message** `string`: What to do, in words: our request or the carrier's note. Absent for otp_required.
