Event URL When you create an Event in Open ACU, each Event will have its own unique Event URL which you can share on your website, social media, email newsletters, etc. To see your Event URL, go to the Event date on the calendar. Under the Event information heading, you'll see a Event URL link: The Event URL will be housed on the Events page on your patient portal, and will contain all the information about your Event you entered when you created the Event: Potential attendees do NOT need to be logged in to the patient portal to view the details on the Event URL. However, they must be logged in to their patient account to register. If they don't have a patient account, they will be prompted to create one.
