Export SMS contacts + consent as CSV (TCPA proof)
Streams the full filtered contact set (same filters as the list, no paging) as CSV — the 4-year TCPA consent-proof export (phone, consent tier, opt-out, first/last contact, latest consent basis/source/timestamp). The same consent + optedOut filters apply, so consent=conversational,express&optedOut=false exports the outbound-ready opted-in list. Use this when… you need the whole set as a file for records/proof (no paging). To read contacts programmatically page-by-page as JSON, use listSMSContacts instead.
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.
Query Parameters
Filter by phone-number substring.
Filter by coarse consent tier. A comma-separated subset of none, conversational, express (compiled to a SQL IN); an unknown value is a 400. Omit for all tiers. The outbound-ready opted-in list is consent=conversational,express&optedOut=false.
"conversational,express"
Tri-state org-wide opt-out (suppression) filter. Omit for all contacts; true = only opted-out (suppressed) numbers; false = only reachable (NOT suppressed) numbers. Combine with consent for the outbound-ready list (consent=conversational,express&optedOut=false).
Response
