Deactivate a brand/campaign registration

Terminates the campaign with the carrier registry so the recurring monthly campaign fee stops (carriers bill the first 3 months of a campaign regardless). Numbers covered by it can no longer SEND texts (receiving is unaffected) until they're registered under a new brand. Irreversible: a deactivated campaign cannot be restored; texting again later requires a new registration (new one-time and review fees). Idempotent.

Create a registration share link

Creates a single-use, expiring link (valid 7 days) that lets someone else (whoever has the legal business details) fill in the carrier registration form for one of your numbers, without a Zernio login. The registration is created under your account once the form is submitted.

Appeal a rejected campaign

Appeals a rejected 10DLC campaign with the carrier registry. Only a registration that reached campaign creation can be appealed; a brand-level rejection should be fixed and re-verified instead. On success the registration returns to `pending`. Content rejections (e.g. an opt-in flow without a verifiable form link, or unrealistic samples) should be FIXED in the same call: pass the corrected `messageFlow` / `sample1` / `sample2` and the campaign is updated before the appeal is filed, so the reviewer sees the new content. The current content is on `GET /v1/sms/registrations/{id}` (`campaignContent`).
