Introduction to WhatsApp

WhatsApp Business Messaging is the world's most popular messaging platform for business communication — a trusted, feature-rich channel that connects you directly with your customers where they already are.

With over 2 billion users worldwide and support for rich media, interactive templates, and real-time conversations, WhatsApp empowers businesses to deliver personalized, engaging customer experiences — no app installs, no email fatigue, no ignored notifications.

Our WhatsApp API is intended for developers who plan to integrate their systems with the Kudosity Messaging API to send WhatsApp messages to their users and/or to build conversational customer experiences.

Why It Matters — For You and Your Customers

If you're a developer building for internal stakeholders or client businesses, WhatsApp unlocks powerful capabilities:

• Verified by Meta – Messages come from your official, verified WhatsApp Business profile with the green checkmark, so customers know it's really you.
• Smart delivery fallback – If WhatsApp delivery fails, we can automatically fall back and send via SMS — ensuring your messages get through.
• Trusted by billions – WhatsApp's end encryption and trusted platform means customers actually read and respond to messages.
• Boost engagement - with 98% open rates and 4-5X higher response rates than email or SMS.
• Simple API Integration - Clean, RESTful API to send templates, text, and rich media messages.

Key WhatsApp Value Propositions

✅ Verified Business Presence on WhatsApp

Messages come from your official WhatsApp Business profile, verified by Meta. No random numbers. No confusion.
Customers can see your business name, logo, and the trusted green verification checkmark — building immediate trust and credibility.

🔁 Smart Routing with SMS Fallback

If a WhatsApp message can't be delivered (e.g. recipient not on WhatsApp or delivery failure), we automatically route it via SMS — no extra code for you to implement.

🔒 Trusted, Encrypted Channel - High Engagement

WhatsApp offers end-to-end encryption and a trusted communication channel that customers actively use and monitor.
With 98% open rates and 45% response rates, your important messages get seen and acted upon — unlike email which often gets lost in spam folders.

🛠 Built for Developers

Our WhatsApp platform is API-first by design, so you can integrate messaging into your product or workflow without waiting for a frontend.
The structure, logic, and endpoints feel familiar — making it simple to adopt, extend, or switch between channels.
