Hi, this is the implementation example of whatsapp-web.js

Watch the tutorials:

• Whatsapp API Tutorial: Part 1
• Whatsapp API Tutorial: Part 2
• Whatsapp API Tutorial: Tips & Tricks

• Whatsapp API Tutorial: Deploy to Heroku

• Clone or download this repo
• Enter to the project directory
• Run npm install
• Run npm run start
• Open browser and go to address http://localhost:8000
• Scan the QR Code
• Enjoy!

As mentioned in the video above, you have to install nodemon to run the start script. You can install nodemon globally with npm i -g nodemon command.

I was added an example to send a message to groups, but before that we must know the group ID (chat ID). Don't worry, I also add the functionality to help you to get that groups ID.

Here the way to get the groups info (including ID & name):

• Send a message to the API number !groups
• The API will replying with the groups info
• Use the ID to send a message
• Here the endpoint: /send-group-message
