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.
