Returns a detailed representation of all schedule baselines for a project
https://api.constructiononline.com/api/baselines/projectID={ID}&detailed=true
This endpoint allows users to obtain all baselines for a project schedule in their ConstructionOnline company account. Users should enter the ID of the project in the URL of the request. If a project in the user's company account matches the provided ID, information about the project schedule's baselines will be returned—specifically, each baseline's ID, name, creation date, and all schedule tasks/groups captured within each baseline.
This endpoint returns a detailed representation of the tasks/groups within each schedule baseline. In addition to the basic properties returned in the compact endpoint (NAME, START_TIME, END_TIME, TYPE, TYPE_NAME), this endpoint will return other properties such as ASAP, COMPLETED, CREATED_BY, and more for each schedule task and group.
