I was disappointed to see Zapier recommended as the way to write Clockify entries back to a Google Calendar. I am currently doing this in Toggl and it is a PITA. It would be so nice to have this integrated into a product vs having to rely on a third party, especially one that is not fit for individual use. Zapier product levels are not suitable for individual use for moderate users. Integromat isn’t that great of a product comparatively to use it instead of Zapier; you get what you pay for IMHO. I would up to a paid account for this feature because it is cheaper than a Zapier plan. Something to think about.
Or IFTT since that is more single user focused (regardless of there data policies).
