Overwrite a dataset

The PUT request body must include the value for the externalId key. This value is unique across all dataset external ID values. To confirm the current value of externalId for a given dataset, call List all datasets or Get a dataset by ID.

Example request body:

{
  "externalId": "Name.csv",
  "keyAttributeNames": ["F1"],
  "description": "Even more data in here than before"
}

On success, this call returns a dataset object describing the updated dataset.
