# SOAP client proxy documentation

This proxy calls the external `SAIFFaxService`† ASMX service to send a single fax with an attachment path, a recipient name, and a fax number; it is consumed by `SAIF.Services.Web.Proxies`, and its one in-repository caller is the WCF service `SAIF.Services.WCF.Services.FaxService`.

| Field | Value |
| --- | --- |
| **Proxy name** | `Fax` |
| **Mechanism** | Service Reference (svcutil) |
| **Generated namespace** | `SAIF.Services.Web.Proxies.Fax` |
| **Generated artifacts** | `Services/SAIF.Services.Web.Proxies/Service References/Fax/Reference.cs` |
| **WSDL document** | `Services/SAIF.Services.Web.Proxies/Service References/Fax/faxservice.wsdl` |
| **Proxy base type** | `System.ServiceModel.ClientBase<T>` |
| **Hand-written wrapper** | `FaxServiceProxy` (`Services/SAIF.Services.Web.Proxies/FaxServiceProxy.cs`) |
| **Consuming project** | `SAIF.Services.Web.Proxies` |
| **Target service** | `SAIFFaxService` (`FaxService` ASMX class) |
| **Endpoint source** | Constructor argument — `EndpointAddress` built by the wrapper from an environment setting; the `app.config` `<client><endpoint>` is present but bypassed |
| **Binding** | `BasicHttpBinding(BasicHttpSecurityMode.TransportCredentialOnly)` constructed in code, Windows client credentials |
| **Operations present** | 1 |
| **Operations called** | 1 |
