• Web services technology

    IdentifierSearch service is based on open standards known collectively as web services, which includes:

    • The Simple Object Access Protocol (SOAP)
    • Web Services Definition Language (WSDL)
    • Extensible Markup Language (XML), XML Schema Definition language (XSD) with the data formatted as XML.


    The IdentifierSearch web service is hosted over a secure connection. It uses the HTTP Basic Authentication method over HTTPS and contains a SOAP formatted XML message carrying a XML payload.



    The operation is available as either SOAPv1.1 or as SOAPv1.2. The ABR currently supports both operations, but we recommend using the latest version.

    The request message in the SOAP envelope is provided as an Identifier‍Search element.


    The server will first validate the identity of an incoming request message. The authentication is used by the ABR to determine the validity of the incoming request. The request will be refused if the identity check fails.

    The IdentifierSearch authentication mode requires a username and password in the HTTP GET request.

    The type of identifier in the IdentifierValue.

    Valid values are “ABN” and ACN/ ARBN”.

    When searching for "ACN or ARBN" you must add the "ACN/ARBN parameters in the <abr:IdentifierValue>ACN/ARBN<IdentifierValue>.

    Data type: s:String

    An ABN or ACN/ARBN eg 12345678955.

    Data Type: s:String

    Specifies whether the search result should only include data elements with an effective "To date" set. Valid values are “Y/N”.

    • If “Y” is specified, the historicalABNRecord element will contain the search result.
