India's fastest RCS messaging API — send rich cards, carousels, OTP, and branded messages on Google's official RCS Business Messaging platform. Trusted by 500+ enterprises.

RCS (Rich Communication Services) is Google's official upgrade to SMS — delivering branded, interactive, app-like experiences directly in the native Android messages app. No app download needed.
Unlike plain SMS, RCS Business Messaging supports images, videos, carousels, quick-reply buttons, and read receipts — making every message a branded, rich experience.
Every RCS business message carries a Google-verified sender badge with your brand logo and name — customers see it's really you, not a spammer.
RCS reaches customers on their default Android Messages app across all major carriers. No WhatsApp, no app install — pure native messaging reach.
RCS messaging delivers 3× higher click-through rates, branded sender identity, and rich interactive formats — all without requiring customers to install any app.
