At 2Chat (2chat.co) we built an integration with Bubble [1] that can help with your fundamental need, which is sending WhatsApp messages. Maybe you can start with that and control the sending using a “delay” or “schedule” function Bubble provides.
If you are using a scheduling tool like Cal.com [2] or YCBM [3], we also have options for them.
To schedule WhatsApp messages for appointment reminders in your application, you can use WhatsApp Business API or third-party services like Twilio. You’ll need to implement a scheduling system that triggers messages -24h and -1h before appointments. Ensure each patient receives a unique consultation link by integrating a mechanism to generate and assign links per appointment.
And for receiving and responding to messages, set up a system that monitors incoming messages, allowing customers to reschedule or cancel appointments. Integrate a feature to reply to these messages through your application’s interface, facilitating communication with customers.
