Reply to a change request

Replies to a reviewer change request on a registration in changes_requested state: a note, hosted document URLs (from POST /v1/sms/opt-in-proof), or both, sent together. The registration returns to requested (back in review), and you do not need to resubmit the whole registration. To change the submitted brand/campaign fields themselves, resubmit via POST /v1/sms/registrations with resubmitRequestId instead.

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`).

Upload opt-in form proof for an appeal

Hosts a screenshot (or PDF) of your SMS opt-in form and returns its public URL. Carrier reviewers reject campaigns whose consent can't be verified and ask for a "link/screenshot of the opt-in form". The registry has no attachment field, so include the returned URL inside the `messageFlow` you submit with the appeal (`POST /v1/sms/registrations/{id}/appeal`).
