About
SMS.es Business Messenger provides business RCS messaging through a REST API and web interface, with campaign management, webhooks, and automatic SMS fallback. Its Campaign API supports creating, cloning, listing, retrieving, updating, activating, pausing, and deleting campaigns. Messages can contain rich cards, carousels, suggested replies, action buttons, high-resolution images and video, location sharing, and branded sender identity. API access uses OAuth2 client credentials, with tokens valid for seven days. Configured webhooks report delivered, read, and user-reply events in real time. Connecting an RCS agent involves creating it in Google’s RCS console and supplying its Agent ID, region, and webhook URL. RCS requires explicit opt-in, which can be managed with web forms and keyword rules. Before launch, agents can message only test devices; public availability depends on carrier approval. Supported test devices are Android with Google Messages and iOS 18 or later. The Inicio tier bills €0.004 per message and includes up to 100K RCS messages per month; Empresa bills €0.0032 per message for 100K–1M monthly messages. The service is presented for promotional, transactional, OTP, and multi-use business messaging.
