GanttFather API documentation

A REST interface to your GanttFather projects at https://api.ganttfather.com/v1 — authenticate with a glt_ token and read or write tasks, dependencies, and resources over HTTPS. Changes made through the API appear on your team's boards live, attributed to the token's integration identity.

Getting started

Authentication, pagination, rate limits, and the error contract.

Projects

The projects your token can read.

Tasks

Create, update, reorder, and assign the work items in a project.

Dependencies

Predecessor links between tasks — finish-to-start and friends.

Resources

Non-human resources — equipment, rooms, budget lines.

Members

A project's roster of people and integration users.
