Create a Schedule Baseline

Generate a new schedule baseline for a project schedule in your ConstructionOnline company account

https://api.constructiononline.com/api/baselines?projectID={projectID}

This endpoint allows users to create a new schedule baseline 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 schedule exists for the project, all tasks/groups for the schedule in its current state will be captured as a new baseline. Only the status of the schedule on the current date can be captured as a baseline; users cannot use this endpoint to create baselines from previous dates or prior schedule statuses. Users also cannot manually create the tasks/groups within the baseline—these are automatically captured by the API if the request is succesful.
