RCS Business Messaging Platform

SpringEdge's RCS Business Messaging API lets you send branded, interactive messages through Google's Rich Communication Services protocol. Messages appear in your customers' native messaging app — Google Messages, Samsung Messages, or their default SMS app — with your verified business name, logo, and rich media content. No app downloads required. When a recipient's device does not support RCS, SpringEdge automatically falls back to SMS, ensuring every message is delivered.

What Is RCS Messaging?

RCS (Rich Communication Services) is a messaging protocol developed by the GSMA and adopted by Google as the successor to SMS and MMS. Unlike SMS, which is limited to 160 characters of plain text, RCS supports high-resolution images, video, audio, file attachments, interactive carousels, suggested reply chips, and call-to-action buttons — all delivered through the phone's native messaging app.

For businesses, RCS Business Messaging (RBM) adds a verified sender profile with your brand name, logo, and business description displayed prominently in the conversation thread. This verified identity eliminates the anonymous sender ID problem that plagues traditional SMS, increasing customer trust and engagement rates. Recipients can see exactly who is messaging them before they even open the message.

RCS is supported by major Indian carriers including Jio, Airtel, and Vodafone Idea, and works natively on Android devices running Google Messages. With over 1 billion monthly active RCS users globally and growing, RCS is rapidly becoming the standard for business-to-customer messaging. SpringEdge provides a unified RESTful API that handles RCS delivery, fallback to SMS, delivery tracking, and read receipts through a single integration.

Why Businesses Choose RCS Messaging

RCS combines the universal reach of SMS with the rich features of messaging apps —
without requiring customers to install anything.

Branded Sender Profile

Google-verified business name, logo, and description visible to recipients before they open the message. Build trust from the first touchpoint.

Rich Media & Carousels

Send high-resolution images, product carousels, video previews, and file attachments directly within the conversation thread.

Interactive Actions

Suggested replies, URL buttons, dial buttons, and calendar actions let customers respond or take action with a single tap.

RCS vs SMS: Feature Comparison

RCS brings app-like messaging capabilities to the native messaging app, while SMS remains the universal fallback for maximum reach.

Feature SMS RCS
Character Limit 160 characters (GSM-7) Up to 8,000 characters
Media Support Text only (MMS is separate) Images, video, audio, files, carousels
Sender Identity 6-character alphanumeric header Verified brand name, logo, description
Interactive Elements None Suggested replies, action buttons, quick actions
Read Receipts Not available Delivered, read, and typing indicators
Rich Cards & Carousels Not available Product carousels with images and CTAs
Fallback Mechanism N/A (SMS is the fallback) Automatic SMS fallback if RCS unavailable
Encryption Not encrypted Transport-layer encryption
Analytics Delivery reports only Delivery, read, click, and engagement tracking
App Required None (native) None (native messaging app)

Automatic SMS Fallback: When a recipient's device does not support RCS or is unreachable via RCS, SpringEdge automatically delivers the message as a standard SMS. This ensures 100% message reachability across all devices and networks. Learn more about our SMS messaging services.

RCS Rich Media Messaging

RICH MEDIA

Rich Media That Drives Engagement

RCS transforms business messaging from static text into visual, interactive experiences. Send high-resolution product images, video demonstrations, PDF brochures, and audio clips directly within the conversation thread. Create scrollable product carousels that let customers browse your catalog without leaving the message.

Businesses using RCS report significantly higher engagement rates compared to SMS — richer content naturally drives more clicks, replies, and conversions. Every media element is fully trackable with delivery confirmations and engagement analytics.

INTERACTIVE ACTIONS

Suggested Actions and Smart Replies

Reduce friction in every customer interaction with tap-to-respond action buttons. Add URL buttons that open a webpage, dial buttons that initiate a phone call, share-location buttons, and add-to-calendar actions — all embedded directly in your RCS message. Customers take action with a single tap instead of typing a response.

Suggested reply chips provide pre-defined response options that customers can tap to instantly reply. Use them for appointment confirmations ("Confirm" / "Reschedule"), order actions ("Track" / "Return"), survey responses, and customer support flows — increasing response rates while reducing handling time.

RCS Verified Business Profile

BRANDED MESSAGING

Verified Sender Identity and Brand Trust

Every RCS message from your business displays your Google-verified sender profile — including your brand name, logo, description, and primary colour. Recipients see exactly who is messaging them, even before opening the conversation. This verification badge builds instant trust and eliminates the spam concerns associated with unknown sender IDs in traditional SMS.

Verified sender profiles also protect your customers from phishing and impersonation attacks. Google's verification process confirms your business identity, ensuring that only authorized messages carry your brand. The result: higher open rates, stronger customer confidence, and a professional messaging experience that reflects your brand standards.

RCS Messaging Use Cases

RCS API Integration

SpringEdge provides a RESTful API for sending RCS messages programmatically. Send text messages, rich cards with images and action buttons, scrollable product carousels, and standalone media files — all through a single API endpoint. The API returns JSON responses and supports webhook callbacks for delivery receipts, read receipts, and user interaction events (button clicks, suggested reply selections).

With a sub-5ms API response time and 99.99% uptime, SpringEdge's RCS API is built for high-throughput production workloads. The platform handles message queuing, carrier routing, fallback to SMS, and retry logic automatically. For businesses already using SpringEdge for SMS or WhatsApp, adding RCS requires minimal additional integration since the API follows the same conventions.

For complete API documentation, code samples in 8+ programming languages (cURL, PHP, Python, Java, Node.js, Go, Ruby, C#), and sandbox testing, visit the Developers API page.

cURL Example — Send an RCS Rich Card

curl -X POST https://web.springedge.com/api/rcs/send \
  -H "Content-Type: application/json" \
  -d '{
    "apikey": "YOUR_API_KEY",
    "to": "919XXXXXXXXX",
    "type": "rich_card",
    "card": {
      "title": "Order Shipped!",
      "description": "Your order #SE12345 has been dispatched.",
      "media_url": "https://example.com/tracking-image.jpg",
      "suggestions": [
        {"type": "url", "text": "Track Order", "url": "https://example.com/track/SE12345"},
        {"type": "reply", "text": "Contact Support"}
      ]
    },
    "fallback_text": "Your order #SE12345 has been shipped. Track: https://example.com/track/SE12345"
  }'

Replace YOUR_API_KEY with your API key. The fallback_text field is delivered as SMS when the recipient does not support RCS.

Frequently Asked Questions about RCS Messaging

  • What is RCS messaging and how does it work?

    RCS (Rich Communication Services) is a messaging protocol developed by the GSMA as the successor to SMS. It works through the phone's native messaging app (such as Google Messages) and supports rich media, interactive buttons, suggested replies, read receipts, and verified sender profiles. Businesses use RCS Business Messaging to send branded, app-like messages without requiring customers to install any additional app. SpringEdge provides the API infrastructure to send RCS messages at scale with automatic SMS fallback.

  • SMS is limited to 160 characters of plain text with no media, no read receipts, and no interactive elements. RCS supports up to 8,000 characters, high-resolution images, video, product carousels, suggested replies, action buttons, read receipts, and a verified sender profile with your brand logo. Both are delivered through the native messaging app, but RCS provides a significantly richer experience. See the comparison table above for a detailed feature-by-feature breakdown.

  • No. RCS messages are delivered through the phone's default messaging app — typically Google Messages on Android devices. There is no separate app to download or install. If the recipient's device supports RCS, they receive the rich message automatically. If their device does not support RCS, SpringEdge delivers the message as a standard SMS instead.

  • RCS is supported on most Android devices running Google Messages, which is the default messaging app on many Android phones. In India, all major carriers — Jio, Airtel, and Vodafone Idea — support RCS delivery. The reach continues to grow as more devices ship with Google Messages as default. Apple has also begun adopting RCS on iPhones with iOS 18, further expanding the addressable audience.

  • SpringEdge automatically detects whether a recipient's device supports RCS. If the device does not support RCS or the user is offline, the message is delivered as a standard SMS using the fallback text you provide in the API request. This ensures 100% message reachability regardless of device type or network conditions. You can configure fallback behaviour and track which messages were delivered via RCS vs SMS in your delivery reports.

  • RCS supports a wide range of media types including JPEG and PNG images, MP4 video, MP3 and OGG audio, PDF documents, and GIF animations. You can send standalone media or embed it in rich cards with titles, descriptions, and action buttons. Product carousels allow you to display multiple cards that users can scroll horizontally, each with its own image, text, and CTA button. Maximum file sizes and supported formats are documented in our API reference.

  • To send RCS messages, your business must be verified through Google's RCS Business Messaging programme. SpringEdge manages the entire verification process for you: submit your business name, logo, website, and description through our dashboard, and our team handles the application with Google. Verification typically takes 5-10 business days. Once approved, your verified profile — with brand logo, name, and description — is displayed to every recipient.

  • Yes, RCS is excellent for marketing campaigns. You can send promotional messages with product images, discount offers, limited-time deals, and one-tap purchase buttons. Product carousels let customers browse multiple items within the message. Suggested reply buttons enable instant engagement ("Shop Now", "View Offer", "Learn More"). RCS marketing messages achieve higher engagement and conversion rates compared to SMS-only campaigns because of the rich, interactive format.

  • RCS messages are priced per message with volume-based discounts, similar to SMS. While the per-message rate for RCS may be higher than plain SMS, the richer format drives significantly better engagement, higher click-through rates, and stronger conversions — often resulting in a better return on investment. Visit our pricing page for current RCS rates and volume tiers.

  • RCS provides granular message status tracking that goes beyond SMS delivery reports. You receive callbacks for: message sent, message delivered, message read, and user interaction (button click, suggested reply selection). SpringEdge delivers these status updates via webhooks in real time, giving you complete visibility into message performance. This data helps you measure campaign effectiveness, identify engagement patterns, and optimise your messaging strategy.

  • Yes. SpringEdge's RCS API is a standard RESTful API that integrates with any CRM, e-commerce platform, marketing automation tool, or custom application. We offer pre-built connectors for popular platforms including Salesforce, HubSpot, Zoho, and Freshworks. You can trigger RCS messages based on CRM events, order status changes, appointment bookings, or any other business workflow. Visit our Add-ons page for available integrations.

  • SpringEdge provides a RESTful API for sending RCS messages. You make an HTTP POST request with the recipient number, message type (text, rich card, carousel, or media), content payload, and an SMS fallback text. The API validates the request, checks RCS capability for the recipient, and routes the message accordingly. Delivery receipts, read receipts, and interaction events are sent to your configured webhook URL. For full documentation and code samples, visit the Developers API page.
