The BHL API will be updated on 25 July 2016 to support changes to the BHL site. These changes will accommodate identifying additional Contributors for Items and Parts of items. First are changes to the API that may affect your existing processes. The Contributor and ContributorID elements in the result sets of API methods that return “Part” information will move. ContributorID will be included as a PartIdentifier in the Identifiers list. Contributor will be included in a new Contributors list. These changes are being made to accommodate more than one contributor per part.
