Conformance to standards
The web service interface is based on the Simple Object Access Protocol (SOAP) 1.1, W3C Note 08 May 2000 (http://www.w3.org/TR/2000/NOTE-SOAP-20000508/).
The provided Web Service Description Language (WSDL) files use Version 1.1, W3C Note 15 March 2001 (http://www.w3.org/TR/wsdl).
All web service calls use the "document-literal" combination of SOAP binding style and data encoding. For a discussion of "document-literal" versus "rpc-encoded" models. For example:

The HTTP layer implements HTTP/1.1 as defined in RFC 2616. Refer to http://www.w3.org/Protocols/rfc2616/rfc2616.html.
The HTTPS implementation is based on the OpenSSL Project, an open source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS 1.1 or later version) protocols. Message Connector uses OpenSSL version 1.1.1g from 21 April 2020. Refer to http://www.openssl.org/. For Kofax Import Connector, certificate for securing web services by HTTPS is one-way SSL. The server (Message Connector) is identified by a server certificate. No certificate is required for the client.
