(PowerShell) Making SOAP Requests using the REST API

There's no reason a SOAP request cannot be sent using the REST API. It's only a matter of adding a SOAP specific header, and providing the SOAP XML request body. The response body is the SOAP response XML.

This example sends a request to ws.cdyne.com to get city weather by zip code.

# This example requires the Chilkat API to have been previously unlocked.

# Host: wsf.cdyne.com
# Content-Type: text/xml; charset=utf-8
# Content-Length: length
# SOAPAction: "http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP"
