Working with a Trumba Calendar
Published on .
Recently I got fed up with my YMCA’s calendar due to all the stuff they overlay on it. They use Trumba (Trumba offers web-hosted event calendar software for publishing online, interactive, calendars of events) who it turns out have a pretty nice API.
The trick is getting the calendar’s “webName” which I get from searching sources in DevTools, then the URL is as simple as https://www.trumba.com/calendars/northshore-ymca.json?startdate=20221206&days=7 (and they also support other formats.)
I only wanted events for one location and certain event titles, so I added a bit for that.
