I'd like to get a SOAP response from https://ec.europa.eu/taxation_customs/vies/checkVatTestService.wsdl, using the below example XML request:
library(RCurl)
xml.request = r'[<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" >
<soapenv:Header/>
<soapenv:Body>
<urn:checkVat xmlns:urn="urn:ec.europa.eu:taxud:vies:services:checkVat:types">
<urn:countryCode>NL</urn:countryCode>
<urn:vatNumber>800938495B01</urn:vatNumber>
</urn:checkVat>
</soapenv:Body>
</soapenv:Envelope>]'
myheader=c(Connection="close",
'Content-Type' = "application/xml",
'Content-length' =nchar(xml.request),
Accept = "multipart/*",
Accept = "text/xml")
data = getURL(url = "https://ec.europa.eu/taxation_customs/vies/checkVatTestService.wsdl",
postfields=xml.request,
httpheader=myheader,
verbose=TRUE)
I am getting this error, thanks for any help:

EDIT: Second method:
r <- POST("https://ec.europa.eu/taxation_customs/vies/checkVatTestService.wsdl", body = body)
stop_for_status(r)
Error: Method Not Allowed (HTTP 405).
content(r)
[1] <body><p>Request method 'POST' not supported</p></body>
The WSDL give the definition of the SOAP endpoint. That's not where you should be posting your request. In the content of the WSDL there is a <wsdlsoap:address location=""> attribute which appears to give the correct URL where you should send your post request. This version of the request seems towk work
