This workflow automates the process of sending SMS reminders for upcoming appointments. It starts with a webhook trigger that receives appointment details from a booking system. The data is then parsed and formatted in a code node, extracting key information such as customer name, phone number, appointment time, and service type. Finally, an SMS reminder is sent via Twilio, personalized with the appointment details. This workflow is ideal for small businesses, clinics, or salons that want to improve client communication and reduce no-shows by automating appointment reminders.
