Indicates the 3-D Secure protocol version.
def get_protocol_version() -> str: ... def set_protocol_version(value: str) -> None: ...
protocol_version = property(get_protocol_version, set_protocol_version)
This property may be used to change the protocol version for communicating with Directory Servers (DS) or Access Control Servers (ACS). As the 3-D Secure protocol 1.0.2 has only recently been adopted, it may be necessary to set this property to "1.0.1" for compatibility with older Directory or Access Control servers. "1.0.1" and "1.0.2" are the only protocols supported by this class.
