Unlike plain SMS, our API lets you send verified, interactive RCS messages with rich media and automatic SMS fallback in under five minutes. We built a clean REST/JSON interface so developers can prototype in the sandbox and move to production quickly. Would love to hear your thoughts on the workflow and docs 😊
