🥗 WAPI

Simple REST API wrapper for the super awesome whatsapp-web.js

⚠️ Due to the nature of the whatsapp-web.js dependency on WhatsApp Web behaviours, regular maintainance is required (library update, temporary workaround). If you face any unknown issue that is not fixed in this wrapper, consider checking whatsapp-web.js issue page
