List opted-out (do-not-text) contacts
List the org-wide opt-out (suppression) list — the numbers you must NOT text — with paging and phone-substring search. Use this when… you specifically want the opt-out subset (and to add/remove entries via addSMSSuppression / removeSMSSuppression). To see ALL contacts with their consent tier (opted-out or not), use listSMSContacts instead; suppressions are just the opted-out slice of that fuller consent dashboard.
Authorizations
Flowyte secret API key (Authorization: Bearer flowyte_sk_live_…). Scope-gated; is scoped to your organization — a key can never reach another tenant. The listed scopes in each operation's apiKey requirement are the scopes that key must hold. The tokenUrl is nominal: keys are minted in the dashboard.
