Let's Begin 🌟

To get started clone the repository from Github:

git clone https://github.com/salman0ansari/whatsapp-api-nodejs.git

Change directory into the project and run

npm install

It will take some time to install the dependencies.

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
