Clockify

About Clockify

Clockify's REST API provides programmatic access to a time-tracking and workforce-management platform, covering users, workspaces, clients, projects, tasks, and time entries. It supports scheduling and capacity planning, holiday and time-off policy management, expense tracking, invoicing, and custom fields on workspaces and projects.

The API includes a separate reporting endpoint for generating shared, summary, detailed, weekly, attendance, and expense reports, as well as an audit log report. Webhooks are available for real-time notifications on events such as starting a timer or deleting an entry, and an experimental entity-changes API exposes created, updated, and deleted entities for syncing external systems.

Authentication is via an X-Api-Key or X-Addon-Token header, with workspace-specific keys required for subdomain-hosted workspaces. The API is intended for developers building integrations, custom reports, or add-ons for the CAKE.com Marketplace, and supports rate limiting and pagination.
