Height

Height is an AI-powered collaborative project management tool that provides a REST API for managing tasks, lists, workspaces, attributes, dependencies, and automation triggers. The API enables developers to programmatically create, read, update, and delete tasks and task lists, manage workspace users and groups, post activity comments, and configure webhook integrations for real-time event notifications. Authentication is handled via secret API keys generated from workspace settings, with OAuth 2.0 available for third-party application integrations. Height announced the shutdown of its service with a final date of September 24, 2025, making this a historical profile of the platform's public developer footprint.

Height publishes 9 APIs on the APIs.io network, including Activities API, Field Templates API, Groups API, and 6 more. Tagged areas include Project Management, Task Management, Collaboration, Productivity, and Workflow-Automation.

The Height catalog on APIs.io includes 1 JSON-LD context.

Height’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/height: open an issue to ask a question, or submit a pull request to add artifacts.
