Clockodo

Clockodo is a German-built, cloud-based time-tracking and project- management application used by service firms, agencies, and freelancers. In addition to its web and mobile apps, Clockodo exposes a REST API at my.clockodo.com that mirrors the objects in the UI: time entries, customers, projects, services, users, absences, holiday quotas, lump-sum services, and a real-time stop-clock. Authentication uses a per-user email plus per-user API key delivered as the X-ClockodoApiUser/X-ClockodoApiKey header pair (or HTTP Basic), and every call must include the X-Clockodo-External-Application header identifying the integrating application.

Clockodo publishes 9 APIs on the APIs.io network, including Absences API, Clock API, Customers API, and 6 more. Tagged areas include Absence Management, Billing, Project Management, Stop Clock, and Time Tracking.

The Clockodo catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Clockodo’s developer surface includes authentication, documentation, engineering blog, pricing, and 10 more developer resources.
