Challenge
Smile Again Dental runs its clinical schedule in Open Dental and its marketing and CRM work in GoHighLevel.
What we built
We built a deterministic n8n workflow on the client's n8n cloud that polls the Open Dental eConnector API every 30 minutes and syncs appointment activity one-way into the GoHighLevel calendar.
Result
Appointments booked in Open Dental are now visible in GoHighLevel on a consistent schedule, so the practice no longer has to maintain the marketing calendar by hand.
Recorded outcomes
Delivery timeline: 1 week. Metrics are shown in the same context as the published engagement.
Smile Again Dental runs its clinical schedule in Open Dental and its marketing and CRM work in GoHighLevel. That split created a visibility problem: appointments created or changed in Open Dental were invisible to the team working inside GHL. Front desk and marketing were effectively looking at two different calendars, which meant manual updates, missed context, and unnecessary back-and-forth.
We built a deterministic n8n workflow on the client's n8n cloud that polls the Open Dental eConnector API every 30 minutes and syncs appointment activity one-way into the GoHighLevel calendar. Because Open Dental does not provide webhooks for this use case, polling was the right design choice. The workflow uses read-only access to Appointments, Patients, Operatories, Providers, AppointmentTypes, and Schedules, applies appointment-type filtering, handles deduplication and matching logic, and keeps a rolling 90-day forward window in sync for new appointments, reschedules, and cancellations.
Appointments booked in Open Dental are now visible in GoHighLevel on a consistent schedule, so the practice no longer has to maintain the marketing calendar by hand. The system gave both teams a shared operational view without changing the source of truth. It also reduced the risk of duplicate entries and calendar drift because the sync logic handles matching and updates in a predictable way.
The implementation path shown here follows the actual engagement summary.
Implementation sequence
n8n polls Open Dental on a
30-minute schedule because the source system does not expose webhooks for this workflow.
The workflow reads upcoming appointment data
from Appointments, Patients, Operatories, Providers, AppointmentTypes, and Schedules.
Appointments outside the 90-day forward window
or outside allowed appointment types are ignored.
Matching and deduplication logic checks whether
the appointment already exists in GoHighLevel and whether it needs a create, update, or cancel action.
The workflow writes the final state
into the GoHighLevel calendar so the marketing and front-desk teams see the same upcoming schedule.
