I did a little testing of Google Calendar today and found that the iCalendars created by Tasks Pro™ and Tasks work just fine. 🙂
Unfortunately, Google Calendar doesn’t seem to support 401 authenticated iCalendars just yet, so you have to choose the URL based authentication option for your Tasks Pro™ or Tasks iCalendar. There is already an option to keep calendars private in Google Calendar, so hopefully they will add support for 401 authentication soon.
This post is part of the project: Tasks Pro™. View the project timeline for more context on this post.

Where can I find the address to the ical format of tasks? The URL produced on my pages (webcal://www.example.com/tasks/icalendar.php) doesn’t seem to work.
Interesting that they don’t support webcal:// – just change the ‘webcal://’ to ‘http://’.
I have a doubt, it works synchronously or I need to import iCal file every time that I need it.
When you subscribe to the iCalendar, it is refreshed on some schedule (they don’t seem to publish the schedule). That is how subscribed iCalendars work.
Hmmm, oddly it doesn’t seem to work for me using either webcal: or the http: prefixes. I always get the same message, “Could not fetch the url because robots.txt prevents us from crawling the url”.
Perhaps you could create a thread in the support forums…
There’s a known issue in gcal where the refresh rate is anywhere from hourly to never. I haven’t seen a single google request in the 4 days since I subscribed to me TP ical feed.
I’m not sure I’m understanding how this works. You say to use URL authentication, but Google Calendar only seems to have a file-upload importing section, not a re-occuring url loading section. Am I wrong about this? I’d love to have my taskspro due dates in gCal.
The answer is in Google calendar’s help pages.
