<Warning>Documentation still in progress</Warning>

Whether you're a Python enthusiast or a Java aficionado, WCE offers two robust engines — **PYWCE** for Python and **JAWCE** for Java — designed to cater to your development preferences without compromising functionality or performance.

> Also supports frappe framework: **frappe-pywce** - for the Frappe / ERPNext developers.

## What is WCE?

It is a unified framework that simplifies the creation of WhatsApp chatbots through a **template-driven approach**.
It abstracts the complexities of managing chat workflows and integrates seamlessly with developer-defined business logic using **reflective APIs**.

The framework empowers developers to:

- **Design Conversational Templates**: YAML-defined templates that map out your chatbot's conversational flow.
- **Hook Business Logic**: Integrate your custom logic effortlessly using reflective APIs.
- **Leverage WhatsApp's Cloud API**: Build reliable chatbots with WhatsApp's powerful messaging platform.

Whether you're looking to create a customer service assistant, automate order processing, or build a dynamic chatbot for your business, WCE provides the tools you need to succeed.

## Why Choose WCE?

### 🚀 **Template-Driven Design**

Define your chatbot's flow using templates (YAML templates supported by default), making it easy to visualize and update conversation logic without diving into complex codebases.

### ⚙️ **Flexible APIs**

Both **PyWCE** and **JaWCE** share a similar API structure, ensuring a seamless transition for developers working across Python and Java.

### 🔗 **Reflective API Integration**

Hook your business logic with minimal configuration. WCE's reflective API maps functions to template hooks dynamically, letting you focus on your application’s core features.

### 🛠 **Cross-Platform Support**

WCE bridges the gap between Python and Java ecosystems, offering:

- **PyWCE**: Optimized for Python developers, leveraging Python's simplicity and rich libraries.
- **frappe-pywce**: Powered by [**pywce@sync**](https://github.com/DonnC/pywce/tree/sync), for frappe / erpnext developers leveraging the frappe framework.
- **JawCE**: Tailored for Java developers, integrating seamlessly with Java's robust enterprise features.

### 📦 **Modular and Scalable**

Each engine is modular, enabling you to start small and scale effortlessly as your chatbot grows in complexity or user base.
