To form this request, it is recommended to first make a request to get a project template. Then, from the response, copy the gid from the object in the requested_dates array. This gid should be used in requested_dates to instantiate a project.
Note: The body of this request will differ if your workspace is an organization. To determine if your workspace is an organization, use the is_organization parameter.
