RCS API vs RCS Portal – which solution is right for your business?

Rich Communication Services (RCS) is the next generation of mobile customer communication. With features such as images, video, buttons, verified sender, and read receipts, RCS creates a more engaging experience than traditional SMS. 

When your company wants to start using RCS, an important question arises: Should you choose RCS API or RCS Portal? 

Both options provide access to powerful RCS functionality – but they suit different needs, organizations, and technical conditions. 

This guide will help you choose the right one. 

What is RCS API? 

RCSAPI is an integration solution that enables you to send and receive RCS messages directly from your existing systems. 

By integrating the RCS API into, for example, CRM, business systems, case management, or marketing platforms, communication can be automated and become a natural part of your existing flows. 

Benefits of the RCS API 

• Automated mailings directly from your systems 

• Full control over logic, content, and timing 

• Ability to handle large volumes 

• Support for advanced and interactive customer dialogues 

• Scalable solution for growing businesses 

When is RCS API most suitable? 

The RCS API is the right choice for companies that: 

• Want to integrate RCS into existing processes 

• Need for automated message flows 

• Handles large volumes of messages 

• Want to build interactive customer journeys 

Example:
An e-commerce company can use the RCS API to automatically send order confirmations with images, delivery updates with tracking buttons, and opportunities for direct customer interaction—all without any manual handling. 

 

What is RCS Portal? 

RCS Portalis a web-based interface where you can manually create, send, and track your RCS mailings. 

No system integration or development resources are required. Everything is handled directly in the portal, making it easy to get started with RCS quickly. 

Benefits of RCS Portal 

• No technical integration required 

• Rapid implementation 

• Simple and user-friendly interface 

• Perfect for campaigns and small mailings 

• Ability to quickly and efficiently test RCS before a potential API integration 

When is RCS Portal most suitable? 

RCS Portal is a great option for companies that: 

• Want to get started quickly 

• Lack of internal development resources 

• Working with manual campaign mailings 

• Want to try RCS as a channel 

Example:
A company can create a campaign with images, call-to-action buttons, and a clear sender profile directly in the RCS Portal and send it to a selected recipient list—without any technical implementation.

Which RCS solution should you choose? 

The choice between RCS API and RCS Portal depends on: 

• How mature your organization is technologically 

• Whether communication should be automated or manual 

• What volumes you plan to send 

• How important integration is for your business processes 

Some companies start with RCS Portal to test the channel's capabilities and then move on to RCS API as their need for automation and integration increases. Others integrate with our APIs right away. Either way, we're with you every step of the way, from registration to sending your first RCS message.
