Breaking the Chat Interface

Chat bubbles have limits. Your app does not.

While standard WhatsApp flows are great for data collection, they fail when you need highly customized, interactive, and branded visual experiences. Webviews bridge the gap between messaging and full mobile apps.

WhatsApp Flows

Native Meta components. Fast, but rigid.

Perfect for lead capture and surveys.
Drag-and-drop building.
Cannot use custom CSS or branding.
No complex JavaScript logic.
Limited to standard input fields.

WhatsApp Webviews Advanced

Your custom code running securely inside the chat.

Built with React, Vue, HTML, CSS.
100% custom UI, animations, and branding.
Interactive Canvas and visual editors.
Securely passes user auth tokens from WhatsApp.
Instant load times without leaving the app.
app.js - OfficialAPIs Webview 
import { initWebview } from '@officialapis/webview';

const waSession = await initWebview();
const userPhone = waSession.phoneNumber;
const authPayload = waSession.encryptedPayload;

renderApp(<FlightSeatSelector user={userPhone} />);

waSession.closeAndSend({
  seats: ['12A', '12B'],
  total: '$45.00'
});

Developer-friendly SDKs.

If you can build a webpage, you can build a WhatsApp Webview. We provide lightweight Javascript SDKs to handle the secure handshake between WhatsApp and your server.

  • Framework agnostic (React, Vue, Angular, Vanilla JS).
  • End-to-end encrypted payload passing.
  • Auto-close functions that seamlessly trigger bot replies.

Zero-Login Authentication.

Never ask a user to log in when they transition from chat to web. WhatsApp passes a securely signed token to your Webview, allowing you to instantly identify the user.

WhatsApp Auth
Your Webview

AES-256 encrypted payload transfer validates user identity without OTPs or passwords.

Authenticated as Alex M.

Loaded existing profile, payment methods, and preferences instantly.

Versatile Applications

If you can code it, you can embed it.

Webviews unlock high-friction industries that require complex visual interactions.

Seat and Ticket Selection

Airlines, cinemas, and event organizers can build interactive visual maps allowing users to pick specific seats.

Dynamic Calculators

Finance and insurance companies can build loan EMI or premium calculators with sliders and real-time chart updates.

Gamification and Quizzes
