Native feature
Bookings, classes, webinars and appointments into the user's calendar: the iOS .ics flow, the honest Android alternatives, and a guide per builder.
From $109 one-time per platform, or let our team do it all from $698.
WebViewGold is set up for Calendar (formerly iCal): a normal link to an .ics file lets the user add the entry to the iPhone or iPad calendar. No URL scheme, no JavaScript bridge, and the web app never reads the user's calendar; it only offers an event.
The Android documentation has no calendar API. Two routes work: add .ics to downloadableExtension in Config.java so the file is downloaded and can be opened with a calendar app that imports .ics files, and offer an "Add to Google Calendar" link that opens outside the app.
Your server returns a small text file (a VCALENDAR with one VEVENT) for each booking, class or appointment. The same URL serves the website, the iOS app and the Android download.
About an hour, most of it the .ics endpoint.
Add a route such as /calendar/BOOKING_TOKEN.ics that returns the event with Content-Type: text/calendar; charset=utf-8. Keep the path ending in .ics, as in the WebViewGold example, and use an unguessable token instead of relying on the login session.
A stable UID per booking, DTSTAMP, DTSTART and DTEND in UTC (ending in Z), SUMMARY, LOCATION and a DESCRIPTION with a link back to the booking. Escape commas and semicolons in text.
A plain <a href="https://yourdomain.com/calendar/TOKEN.ics">. Do not open it in a new window or with target="_blank"; a web view has nowhere to show one.
Add .ics to downloadableExtension in Config.java for the download route, and show an "Add to Google Calendar" link with calendar.google.com in BROWSER_BLACKLIST, so it opens in the system browser, where most users are signed in to Google, instead of inside the web view.
Add an event on an iPhone, then check the time zone, the duration and the link in the description. On Android, try phones from two manufacturers; calendar apps differ in how they open downloaded .ics files.
Not a dedicated one; the calendar integration in the docs is iOS only. On Android, offer the .ics file as a download (add .ics to downloadableExtension in Config.java) and an Add to Google Calendar link that opens outside the app.
No. The .ics flow only offers an event that the user adds. Availability belongs on your server, based on your own booking data.
Yes, inside the .ics file: an RRULE line for repeating classes and a VALARM block for a reminder. How the reminder appears depends on the user's calendar app; for reminders you control, use push notifications.
Same result, different amount of work on your side. All three come with the approval guarantee and 24/7 human support.
