Transmit SMS API
Classic v1 REST API — fully supported, not deprecated. SMS sending with single-request multi-recipient batches and custom tracked-link domains, plus everything v2 does not carry: contacts, lists and custom fields, bulk CSV import, dedicated virtual numbers, inbound keywords, email-to-SMS and all campaign reporting. 35 operations, OpenAPI 3.0.0, JSON or XML responses. Authenticated with HTTP Basic (API key + account secret).
