Contract source

The contract on this page is read from src\WCF\SAIF.Services.WCF.Host\Service References\Legacy.Fax\faxservice.wsdl, the checked-in WSDL captured at generation time. The generated Reference.cs is svcutil tool output cited only to confirm the proxy type name (FaxServiceSoapClient), its base type, and its SOAP action; it is not the source of the contract described below.

Operations

Operation	SOAP action	Input message	Output message	Faults	Called in this repository
Send	http://www.saif.com/Send	SendSoapIn — part parameters, element tns:Send	SendSoapOut — part parameters, element tns:SendResponse	None declared	Yes — details

Messages and types

Type	Kind	Members	Used by
Send	Complex type	FaxJob (tns:FaxInfo, optional)	Send (input)
FaxInfo	Complex type	Attachment (s:string), CoverSheetNote (s:string), ToCompanyName (s:string), ToFaxNumber (s:string), ToName (s:string), ToVoiceNumber (s:string) — all optional	Send (input, via FaxJob)
SendResponse	Complex type (empty)	None	Send (output)

FaxInfo

Member	Type	Required	Purpose
Attachment	s:string	Not stated in the WSDL	The path to the fax attachment; this repository populates it with a temporary file path, not the file content*
CoverSheetNote	s:string	Not stated in the WSDL	Cover sheet note text; never populated by this repository's call site
ToCompanyName	s:string	Not stated in the WSDL	Recipient company name; never populated by this repository's call site
ToFaxNumber	s:string	Not stated in the WSDL	Recipient fax number; populated from FaxRecipient.FaxNumber
ToName	s:string	Not stated in the WSDL	Recipient name; populated from FaxRecipient.RecipientName
ToVoiceNumber	s:string	Not stated in the WSDL	Recipient voice callback number; never populated by this repository's call site

Faults

The WSDL declares no faults. A failure reaches this repository as a generic SOAP fault surfaced by the proxy; see Consumption for how the call sites handle it.

Binding details

Aspect	Value
Transport	HTTP
Message version	SOAP 1.1
Security mode	None declared in the WSDL — set in code, see Architecture
Declared message size limits	None declared in the WSDL

The WSDL also declares a FaxServiceSoap12 port (SOAP 1.2) at the same address; this repository binds only the SOAP 1.1 FaxServiceSoap port, so FaxServiceSoap12 is not used.

Contract drift risk

Aspect	Finding
WSDL captured at	Not determined from source
Live service documented by this run	No — `FaxService`† is not one of this run's soapServiceHosts and has no docs/services/<slug>/ folder generated by this run
Verification possible	Not possible from this repository; the captured WSDL cannot be compared against the live service without external access to `FaxService`†
Consequence of drift	If the remote Send operation's shape changes, the generated proxy and this contract page are both stale until the reference is refreshed, and no automated check in this repository would detect the mismatch
