By popular request, we’ve just released support for manipulating timeslip timers to our API.
You can now
https://api.freeagent.com/v2/timeslips/:id/timer to start a timer, or
DELETE to the same URL to stop a timer for a timeslip.
Additionally we’ve added a filter to the
https://api.freeagent.com/v2/timeslips?view=running endpoint which allows existing timeslips to be filtered to only show timeslips with running timers.
Full documentation is available at https://dev.freeagent.com/docs/timeslips#timers
Hope that helps some of you out.
