+# WhatsApp and Llama 4 APIs : Build your own multi-modal chatbot
+
+Welcome to the WhatsApp Llama4 Bot ! This bot leverages the power of the Llama 4 APIs to provide intelligent and interactive responses to users via WhatsApp. It supports text, image, and audio interactions, making it a versatile tool for various use cases.
+
+
+## Key Features
+- **Text Interaction**: Users can send text messages to the bot, which are processed using the Llama4 APIs to generate accurate and contextually relevant responses.
+- **Image Reasoning**: The bot can analyze images sent by users, providing insights, descriptions, or answers related to the image content.
+- **Audio-to-Audio Interaction**: Users can send audio messages, which are transcribed to text, processed by the Llama4, and converted back to audio for a seamless voice-based interaction.
+
+
+
+## Technical Overview
+
+### Architecture
+
+- **FastAPI**: The bot is built using FastAPI, a modern web framework for building APIs with Python.
+- **Asynchronous Processing**: Utilizes `httpx` for making asynchronous HTTP requests to external APIs, ensuring efficient handling of media files.
+- **Environment Configuration**: Uses `dotenv` to manage environment variables, keeping sensitive information like API keys secure.
+
+Please refer below a high-level of architecture which explains the integrations :
+![WhatsApp Llama4 Integration Diagram](src/docs/img/WhatApp_Llama4_integration.jpeg)
+
+
+
+
+
+### Important Integrations
+
+- **WhatsApp API**: Facilitates sending and receiving messages, images, and audio files. 
+- **Llama4 Model**: Provides advanced natural language processing capabilities for generating responses.
+- **Groq API**: Handles speech-to-text (STT) and text-to-speech (TTS) conversions, enabling the audio-to-audio feature.
+
+
+
+
+
+## Here are the steps to setup with WhatsApp Business Cloud API
+
+
+First, open the [WhatsApp Business Platform Cloud API Get Started Guide](https://developers.facebook.com/docs/whatsapp/cloud-api/get-started#set-up-developer-assets) and follow the first four steps to:
+
+1. Add the WhatsApp product to your business app;
+2. Add a recipient number;
+3. Send a test message;
+4. Configure a webhook to receive real time HTTP notifications.
+
+For the last step, you need to further follow the [Sample Callback URL for Webhooks Testing Guide](https://developers.facebook.com/docs/whatsapp/sample-app-endpoints) to create a free account on glitch.com to get your webhook's callback URL.
+
+Now open the [Meta for Develops Apps](https://developers.facebook.com/apps/) page and select the WhatsApp business app and you should be able to copy the curl command (as shown in the App Dashboard - WhatsApp - API Setup - Step 2 below) and run the command on a Terminal to send a test message to your WhatsApp.
+
+![](../../../src/docs/img/whatsapp_dashboard.jpg)
+
+Note down the "Temporary access token", "Phone number ID", and "a recipient phone number" in the API Setup page above, which will be used later.
+
+
+
+
+
+## Setup and Installation
+
+
+
+### Step 1: Clone the Repository
+
+```bash
+git clone https://github.com/meta-llama/internal-llama-cookbook.git
+cd internal-llama-cookbook/end-to-end-use-cases/whatsapp-llama4-bot
+```
+
+### Step 2: Install Dependencies
+
+Ensure you have Python installed, then run the following command to install the required packages:
+
+```bash
+pip install -r requirements.txt
+```
+
+
+
+### Step 3: Configure Environment Variables
+
+Create a `.env` file in the project directory and add your API keys and other configuration details as follows:
+
+```plaintext
+ACCESS_TOKEN=your_whatsapp_access_token
+WHATSAPP_API_URL=your_whatsapp_api_url
+TOGETHER_API_KEY=your_llama4_api_key
+GROQ_API_KEY=your_groq_api_key
+PHONE_NUMBER_ID=your_phone_number_id'
+```
+
+
+
+### Step 4: Run the Application
+
+On your EC2 instance, run the following command on a Terminal to start the FastAPI server 
+
+```bash
+uvicorn ec2_endpoints:app —host 0.0.0.0 —port 5000
+```
+
+Note: If you use Amazon EC2 as your web server, make sure you have port 5000 added to your EC2 instance's security group's inbound rules.

 If you are new to developing with Meta Llama models, this is where you should start. This folder contains introductory-level notebooks across different techniques relating to Meta Llama.
 
 * The [Build_with_Llama 4](./build_with_llama_4.ipynb) notebook showcases a comprehensive walkthrough of the new capabilities of Llama 4 Scout models, including long context, multi-images and function calling.
+* The [Build_with_Llama API](./build_with_llama_api.ipynb) notebook highlights some of the features of [Llama API](https://llama.developer.meta.com?utm_source=llama-cookbook&utm_medium=readme&utm_campaign=getting_started).
 * The [inference](./inference/) folder contains scripts to deploy Llama for inference on server and mobile. See also [3p_integrations/vllm](../3p-integrations/vllm/) and [3p_integrations/tgi](../3p-integrations/tgi/) for hosting Llama on open-source model servers.
 * The [RAG](./RAG/) folder contains a simple Retrieval-Augmented Generation application using Llama.
 * The [finetuning](./finetuning/) folder contains resources to help you finetune Llama on your custom datasets, for both single- and multi-GPU setups. The scripts use the native llama-cookbook finetuning code found in [finetuning.py](../src/llama_cookbook/finetuning.py) which supports these features:
