# 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.
