About

A WhatsApp API client that operates via the WhatsApp Web browser.

The library launches the WhatsApp Web browser app via Puppeteer, accessing its internal functions and creating a managed instance to reduce the risk of being blocked. This gives the API client nearly all WhatsApp Web features for dynamic use in a Node.js application.

Important

It is not guaranteed you will not be blocked by using this method. WhatsApp does not allow bots or unofficial clients on their platform, so this shouldn't be considered totally safe.
