Concepto Móvil RCS API vs RCS-Box

Concepto Móvil RCS API lets businesses send interactive RCS messages and manage campaigns through the Broadcaster RCS web portal. Messages can contain images, video, GIFs, carousels, and interactive cards; buttons can open URLs, place calls, show locations, or provide predefined replies. Businesses can use a name and logo verified by Google. The product lists delivery, read, click, and interaction metrics, along with real-time webhooks for delivery, read, and interaction events. If a recipient’s device does not support RCS, the API provides automatic SMS fallback. The API uses HTTPS REST, access tokens, and JSON encoded as UTF-8. Customers must request registration of their public IP address to receive authentication credentials. Broadcaster RCS includes a visual editor, templates, exclusion lists, campaign scheduling, and reports, and is designed for campaign management without programming. The API can integrate with existing applications such as CRMs, ERPs, and payment gateways. Pricing is on request; the listed trial lasts 14 days with no commitment. Concepto Móvil is based in Mexico City and lists ISO 27001 as its information security management certification.

RCS-Box is a multi-tenant API for Google RCS Business Messaging, with EU hosting and a German contract partner. It supports text with suggestions, rich cards, carousels, XL messages, and automatic video and image unfurling. Webhooks can deliver incoming messages and opt-in or opt-out events; forwarded webhooks carry an HMAC-SHA256 signature calculated with the tenant API key. Each tenant has a dedicated key and brand-level isolation, plus a configurable country allowlist that defaults to Germany with the +49 prefix. The API manages STOP and START blacklist status per agent. Plans can use standard or newsletter mode, with newsletter billing based on active recipients per month. XL messages are available in all plans from Skizze and count as one conversation. The Free plan costs nothing and includes 100 sessions per calendar month. Skizze costs €49 a month, Atelier €249 a month, and Manufaktur €999 a month. The API is presented for development teams and technology leaders in startups, scale-ups, and enterprise technology units.
