Clockodo API
The Clockodo API is a REST interface at my.clockodo.com that lets developers automate time tracking and project management. v2 endpoints under /api/v2 cover entries, customers, projects, services, users, lump-sum services, and the stop-clock; legacy endpoints under /api cover absences and holiday quotas. Calls authenticate with X-ClockodoApiUser plus X-ClockodoApiKey (or HTTP Basic with the same credentials) and identify the calling app via X-Clockodo-External-Application; responses are JSON.
