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, Stopclock, 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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/clockodo: open an issue to ask a question, or submit a pull request to add artifacts.
