01
Read card due dates from Flux
Use the Flux REST API to fetch board data (GET /api/boards/{boardId}). The response includes every card with its dueDate, startDate, and dueComplete fields. Filter for cards with upcoming due dates.
// Google Calendar + Flux
Due dates in your calendar.
Sync Flux card due dates with Google Calendar. See kanban deadlines alongside meetings, plan your week with full visibility. Apps Script, Zapier, or any automation tool handles the bridge.
02
Create Google Calendar events
Use Google Apps Script, the Google Calendar API, or an automation platform to create calendar events from Flux card due dates. Set the event title to the card title and the event date to the card due date.
03
Schedule periodic syncs
Set up a scheduled trigger (Apps Script timer, Zapier schedule, or cron job) to run the sync periodically. Each run fetches current due dates from Flux and creates or updates corresponding calendar events.
04
Handle updates and completions
When a card due date changes in Flux, update the corresponding calendar event. When a card is marked complete (dueComplete: true), optionally remove the event or mark it as completed in the calendar.
01 Is the sync bidirectional?
+
Not automatically. Flux does not watch Google Calendar for changes. The typical setup is one-way: Flux due dates push to Google Calendar. If you need calendar-to-Flux sync, you would build a separate automation that reads calendar events and updates Flux cards via the API.
02 Can I use Zapier for this instead of Apps Script?
+
Yes. Zapier, Make, and n8n can all bridge Flux and Google Calendar. Set up a scheduled trigger that calls the Flux API, then use the Google Calendar action to create events. This avoids writing any code.
03 Which card fields map to calendar events?
+
The key fields are dueDate (event date), title (event title), startDate (optional event start), and dueComplete (whether the task is done). You can also include the board name and column name in the event description for context.
