It’s not always an easy call. Both approaches offer distinct advantages, but the right choice depends on your team’s technical capabilities, business goals, and long-term messaging strategy, and at Kero, we get that. That’s why we offer both depending on your RCS Business Messaging needs: powerful APIs to integrate with your systems and a sleek, ready-to-go WebApp. 

Here’s how to choose the best path for your RCS Business Messaging (RBM) deployment. 

1. RBM via API Offers Flexibility and Control 

If you have an in-house development team or work with technical partners, integrating RCS Business Messaging through the Kero APIs gives you maximum control over your mobile communication campaigns. Our APIs allow you to: 

• Customise message flows and UX, 

• Integrate directly into your CRM or backend system, and 

• Maintain brand consistency across all touchpoints.  

An API-based approach is ideal for enterprises that already have vigorous systems in place and want to own the user journey from end-to-end. It’s also a good fit for businesses running omnichannel communication strategies that require tight integration with other channels like WhatsApp, push notifications, or email. 

However, this route often requires developer time and resources and ongoing maintenance. 

2. RBM WebApp Offers Speed and Simplicity 

As a full-service RCS Business Messaging platform, Kero offers a ready-to-use interface, often with drag-and-drop campaign builders, pre-built templates, analytics dashboards, and built-in fallback options like SMS. This is a great option if: 

• You want to launch and manage campaigns quickly, 

• Your team lacks technical bandwidth, and 

• You’re focused on marketing, customer service, or lead nurturing rather than deep backend integration with your existing systems.  

Kero handles the heavy lifting so your team can focus on content and performance, not infrastructure. 

So, which one is right for you? 

Whether you choose an API integration with Kero or our WebApp, the goal is the same: to deliver rich, engaging customer conversations through the RCS Business Messaging (RBM) channel. If you’re building for scale and want to deeply integrate RBM into your ecosystem, APIs are a powerful option. But if you’re looking to get up and running quickly with fewer technical hurdles, the WebApp might be your best bet.
