Hi César! I'm a big fan of Chatwith and have several licenses, always seeking ways to enhance its capabilities.

Last week I've found a tool here on Appsumo, WBizTool, an excellent alternative to the WhatsApp API. They handle webhooks and apis so I think native integration with Chatwith for reminders and other messages with our own whatsapp would be FAN-TAS-TIC.
Could you take a look and let me know if it's feasible?
