Development of the system centered around building a resilient, low-latency automation capable of responding to real-time availability constraints. The core feature was the implementation of a rolling counter logic, designed to intelligently screen through available time slots. If the current day was fully booked, the system would automatically roll forward to the next available date, repeating this process until it found a suitable opening. This was achieved using conditional logic within N8N, dynamically querying Cal.com’s API and iterating through the calendar with fallback conditions until a valid slot was returned.
