What is RCS Messaging?

Rich Communication Services (RCS) is a mobile messaging protocol designed to replace SMS with more advanced features. It provides a richer, more interactive experience by allowing businesses to send branded messages with multimedia content, interactive carousels, and AI agents for customer support. Unlike messaging apps that require installation, RCS works within the default messaging app on Android devices, making it widely accessible.

With RCS, businesses can enhance their communication by integrating verified sender IDs, automated workflows, and real-time engagement tracking. This helps improve customer trust, drive higher response rates, and deliver seamless messaging experiences.

Key features of RCS messaging

Kudosity’s RCS messaging platform enables businesses to:

• Send and receive rich media messages, including images, videos, GIFs, and documents.

• Enable interactive chat experiences with suggested replies and action buttons.

• Automate customer interactions using AI-powered agents.

• Provide real-time delivery tracking, read receipts, and typing indicators.

• Ensure secure, reliable messaging with verified sender IDs and encryption.

With these capabilities, businesses can create app-like experiences without requiring customers to download additional software.

RCS Messaging functionalities

Kudosity’s Messages API provides an advanced framework for integrating RCS into business workflows. The platform supports:

• Bulk messaging for marketing campaigns, promotions, and customer updates.

• Two-way messaging for personalised customer support and engagement.

• Conversational AI to automate responses and streamline interactions.

• RCS payments and transactional messaging for seamless customer experiences.

By leveraging RCS, businesses can drive engagement, enhance operational efficiency, and provide real-time customer support.

RCS Device support

RCS is supported on a wide range of Android devices that use the Google Messages app or carrier-supported RCS services. Many major mobile carriers and manufacturers support RCS, enabling businesses to reach a broad audience.

However, not all devices and operating systems currently support RCS. Apple iOS, for example, does not yet offer RCS functionality. To ensure message delivery to all customers, Kudosity provides fallback options that automatically switch to SMS when RCS is not available.

Technical specifications and limitations

RCS messaging offers advanced capabilities, but businesses should be aware of certain technical constraints. These include:

• Supported media types such as PNG, JPEG, MP4, GIF, and PDF.

• Maximum file sizes, with limits on images, videos, and documents.

• Character limits for messages, allowing up to 4,000 characters per RCS message.

• Network and device dependencies that may affect message delivery and feature availability.

Understanding these specifications helps businesses optimise their RCS messaging strategies while ensuring reliable and efficient communication.

RCS APIs and SDKs for Developers

Kudosity offers powerful APIs and SDKs that allow developers to integrate RCS messaging into their applications. These tools provide:

• Access to Messages API for sending and receiving RCS messages.

• Webhooks for real-time message tracking and delivery reports.

• AI-powered customer support for automated customer interactions.

Developers can explore further API documentation and implementation details through external resources.

Secure API integration and why it matters

Security is critical for business messaging. Kudosity’s secure APIs ensure that all RCS communications are protected, meeting compliance standards such as GDPR and CCPA. Secure API integration provides:

• Encryption to protect customer data and prevent interception.

• Verified business sender IDs to reduce phishing and unauthorised messaging.

• Secure authentication protocols to safeguard sensitive transactions.

By using a secure messaging framework, businesses can build trust, reduce risks, and maintain compliance while delivering high-quality customer interactions.

Developer tools for RCS integration

Kudosity provides a range of developer tools to simplify RCS implementation, including:

• Readme IO API testing for streamlined development and debugging

• Real-time webhooks for live message tracking and automation

• No-code and low-code connectors for quick integration with business applications

These tools allow developers to build scalable, efficient RCS messaging solutions that align with business objectives.
