A calendar feed is a secret URL that serves your deadline docket as a calendar. Subscribe to it once in your calendar app. From then on the app fetches it again by itself, so new deadlines appear, moved dates move and finished ones are marked done without you exporting anything.
We are switching the docket on organization by organization. Until it is on for yours, the calendar feed routes answer 403 with code docket_not_enabled. Email support@signa.so to have it switched on.

​
Create a feed

Pass portfolio_id to limit the feed to one portfolio, for example one client’s marks. The url is shown only in this response, so copy it now. Anyone with the URL can read the calendar. See Create Calendar Feed.

​
Subscribe

Subscribe to the URL rather than downloading it. A downloaded file is a copy that never changes.
  1. Open Google Calendar on the web (the mobile app cannot add a URL).
  2. Next to Other calendars, click +, then From URL.
  3. Paste the feed URL and click Add calendar.
The calendar then appears on every device signed in to that Google account.

​
How current the calendar is

Your calendar app decides when it fetches the feed, not Signa. Google Calendar and Outlook refresh subscribed calendars on their own schedule, which can be a day or more, and you cannot make them refresh sooner. Apple Calendar follows the auto-refresh interval you set. Signa rechecks the docket against office data on its own schedule, and a change reaches your calendar at the app’s next fetch after that. So a calendar is a view of your deadlines, not an alarm. For a deadline you must not miss, rely on email reminders, which Signa sends itself, or read List Deadlines directly. Each event says when Signa last checked the mark against office data (“Checked 2026-11-10”), and an event whose date the office’s published closure days do not yet cover says so (“Office closure days are not confirmed for this date; check the office calendar”).

​
What the calendar holds

  • Every open deadline that is overdue or due within the next 24 months, including the ones you added yourself.
  • A second event on the last day of the grace period, when a deadline has one.
  • Deadlines marked done in the last 30 days, titled “Done: …”, so a colleague sees the work was done.
Events are all-day, shown as free time, and carry no alarms. Each names the mark, office and number, the deadline, what happens if it is missed and a link to the office record. Notes and assignees are never in a feed: the URL may end up in shared calendars. Dismissed deadlines are left out. A deadline Signa no longer computes from office data stays on the calendar with “Needs review” until you close it.

​
Revoke a feed

Delete Calendar Feed revokes a feed. For 90 days its URL serves a single event saying it was revoked, then nothing. Signa also revokes a feed when its portfolio is deleted, and the feeds a member’s API keys created when the member is removed. List Calendar Feeds shows each feed’s last_fetched_at, so you can spot one nobody uses. An organization can have 20 feeds.
