Introduction

This tutorial provides a comprehensive guide on how to use a free and unlimited WhatsApp API, as discussed in the video from Comunidade ZDG. Whether you want to automate conversations, create chatbots, or integrate with various applications, this guide will help you navigate the process effectively, even if you have no programming background.

Step 1: Setting Up Your WhatsApp API

1. Choose the Right API:

   • Select an API suited for your needs. Options include Baileys, Venom-BOT, WPPConnect, WWeb-JS, and Cloud API.
   • Consider your specific requirements such as ease of use, features, and integration capabilities.

2. Access the Documentation:

   • Visit the official documentation for the API you choose. This will provide detailed instructions and examples.
   • Familiarize yourself with the setup process, libraries required, and authentication methods.

3. Create a WhatsApp Business Account:

   • Sign up for a WhatsApp Business account if you don’t have one.
   • Ensure your phone number is verified and linked to the account.

Step 2: Installing Necessary Tools

1. Install Node.js:

   • Download and install Node.js from the official website.
   • Ensure that npm (Node Package Manager) is also installed, as it is needed for package management.

2. Set Up Your Development Environment:

   • Use a code editor like Visual Studio Code or Sublime Text.
   • Create a new project folder for your WhatsApp API integration.

3. Install API Libraries:

   • Open your terminal and navigate to your project folder.
   • Use npm to install the API library. For example, for Baileys, run:

     npm install @adiwajshing/baileys
     

Step 3: Writing Your First Script

1. Create a Basic Script:

   • In your project folder, create a new file (e.g., app.js).

   • Start by requiring the installed library and set up your connection:

     const { default: makeWASocket } = require('@adiwajshing/baileys')
     
     const sock = makeWASocket()
     

2. Implement Message Handling:

   • Add the code to handle incoming messages:

     sock.ev.on('messages.upsert', async (m) => {
         console.log('Received message:', m.messages[0].message)
     })
     

3. Run Your Script:

   • In the terminal, execute your script using:

     node app.js
     

Step 4: Automating Responses

1. Set Up Automated Replies:

   • Modify your message handling logic to respond automatically based on keywords:

     if (m.messages[0].message.conversation.includes('Hello')) {
         await sock.sendMessage(m.messages[0].key.remoteJid, { text: 'Hi there!' })
     }
     

2. Test Your Automation:

   • Send a message to your WhatsApp number to see if the automated response works.

Step 5: Advanced Integrations

1. Explore Integrations with Other Platforms:

   • Look into how you can integrate your WhatsApp API with other applications like WordPress, Shopify, or Google Sheets.
   • Use API documentation from those platforms to guide your integration process.

2. Utilize Chatbot Frameworks:

   • Consider using frameworks like Dialogflow or Botpress to create more sophisticated chatbots.
   • Follow their setup guides to integrate with your WhatsApp API.
