Dataset: Delete Introduction
The Dataset: Delete Web service is used to delete an existing dataset in an OSF Web Services instance. When a dataset gets deleted, all of the information archived in it is deleted as well. There is no way to recover any data once this query is issued.
(Alternatively, if you simply want to unpublish all the records to keep the revisions of a given dataset, then use the Revision: Update Web service endpoint.)
Developers communicate with the Dataset: Delete Web service using the HTTP GET method. You may request any of the available content types (*/*).
