Updating an existing task

Note that the data for this particular endpoint is a bit different to the others, it accepts an array of property / value pairs. You can pass through as many pairs as you want, only the properties you pass through will be updated.

Note that if you specify an actual effort value it will be generic effort and not for a specific resource. If you want specific resource effort see timesheets. Date values must be in ISO Date format: var d = new Date("2015-03-25T12:00:00-06:30");
