delete https://api.shift.io/v3/assets//metadata/
Removes a specific key/value pair from an asset
This call requires two path parameters: an asset id and the key of whichever key/value pair you want to remove from the asset. A 204 code is returned when the key/value pair is successfully deleted.
Note that you are only deleting the key/value pair that corresponds to the key you entered; the rest of the metadata will remain unaffected.
