ICS File Generator
· Generate RFC 5545-compliant ICS calendar files directly from Bubble data, with no external services or APIs required
· Single Event mode for straightforward use cases and Multi Event mode to export an entire list of Bubble records into one calendar file
· All-day event support using the DATE format, fully compatible with Apple Calendar, Google Calendar, and Outlook
· Per-event timezone support using IANA timezone identifiers - events render at the correct local time in any calendar app

Multiple Events
· Multi Event mode accepts a JSON array so you can pack any number of events into a single ICS file from one action call
· Each event in the array is fully independent - different dates, timezones, titles, recurrence rules, and attendees per event
· Ideal for exporting a user's full schedule, a course calendar, or an event series as a single downloadable file

Organizer & Attendees
· Organizer field embeds a named sender with display name and email address in every event
· Attendees field accepts a JSON array of guests, each with their own email and optional display name
· Each attendee is written as a required participant with NEEDS-ACTION status, which triggers accept/decline prompts in most calendar clients
· Attendees can be set independently per event in Multi Event mode

Recurring Events
· Built-in Recurrence Preset field accepts any RRULE frequency string - daily, weekly, monthly, yearly, or any combination with day and interval modifiers
· Recurrence Until field caps the series at a specific end date; Recurrence Count caps it after a set number of occurrences
· Full RRULE Override field for complex patterns that the preset fields cannot express - bypasses the preset entirely and writes the rule as-is
· Recurrence rules can be set independently per event in Multi Event mode

Reminders
· Alarm block embeds a DISPLAY reminder a configurable number of minutes before the event start
· Compatible with all major calendar clients that support VALARM

Client-Side Delivery
· Download mode triggers a direct browser file download - no server round-trip, no storage costs
· Save to Bubble mode uploads the generated file to Bubble's CDN via the built-in upload mechanism and exposes the resulting URL as a state
· Both modes can run together in a single action call

Backend Support
· Dedicated server-side action generates ICS files in backend workflows with no user interaction required
· Returns the raw ICS text, a base64-encoded copy, and the filename - ready to pass to the companion upload action or any API
· Companion upload action posts the file directly to Bubble's CDN using the app's file upload endpoint and returns a usable https URL
· Upload action automatically handles live and test mode URLs by accepting the Website Home URL dynamic value
