Nueva EPS members' appointments, in Calendly. With Arbol, with no manual copying.
How it works
The Nueva EPS member calls or writes to your organization.
The assistant asks for the Nueva EPS order and authorization before offering a slot.
It checks availability in Calendly and creates the appointment as an event on the clinician's calendar.
If the patient reschedules, it moves it in Calendly and lets your team know.

Calendly
Calendly is a meeting scheduling platform founded in 2013 by Tope Awotona. Each user connects their calendars, sets their hours and shares a link or booking page where the other person picks an open time. It also sends email and text reminders, lets invitees reschedule without the back-and-forth, and can collect payment up front at booking.
Share a booking link so patients pick their appointment time based on each provider's schedule.
According to the company, more than 50 million people use Calendly, and more than 1.3 billion meetings have been booked on it. Source: calendly.com (opens in a new tab)
Calendly publishes a REST API, with OAuth 2.0 or a personal access token, to book meetings and read and write scheduling and contact data; its webhooks fire when someone books or cancels, and the booking page can be embedded on a website.
