Introduction

AmbirScan Web Connect enables web applications to control local TWAIN scanners through a simple JavaScript SDK. It bridges the gap between browser-based applications and hardware scanners by providing a local Windows service that your web app communicates with via a REST API.

How It Works​

┌──────────────────┐    HTTPS (REST API)    ┌────────────────────────┐    Internal    ┌─────────────┐
│   Your Web App   │ ◄──────────────────── │  AmbirScan Web Connect │ ◄───────────► │   Scanner   │
│   (Browser)      │   localhost:53052      │  (Windows Service +    │    TWAIN      │   Hardware  │
│                  │                        │   Desktop App)         │               │             │
└──────────────────┘                        └────────────────────────┘               └─────────────┘
  1. Your web application includes the JavaScript SDK (aswcn-scanner-bridge.js)
  2. The SDK communicates with the locally installed AmbirScan Web Connect service over HTTPS on localhost:53052
  3. The service interfaces with TWAIN scanners and returns scanned images as Base64-encoded data

Live Demo​

A hosted demo application is available for developers to test scanning without building their own web app:
