What is Whatsapp? 🤷

WhatsApp is a mobile messaging application which allows you to send and receive messages without having to pay for SMS.

WhatsApp's end-to-end encryption ensures that your messages are secure from third parties like hackers and government surveillance programs.

If you going to use webhook make sure to create a .env file in the project root. Inside the file add:

WEBHOOK_URL=https://your webhook url

Finally, run npm run start in the project root to start the server. Our applications will be accessed at

http://localhost:3333

To initialise a server make a GET request
Note: Don't forgot to save KEY value.

ENDPOINT: /init

To scan QR code make a GET request

ENDPOINT: /qrcode?key=KEY
