Remove namespace from Savon SOAP request - ruby

Question

I've this code that uses Savon that I'm trying get to work.
require "savon"
require "time"
Gyoku.configure do |config|
config.convert_symbols_to(&:tap)
end
client = Savon::Client.new("https://www.cfhdocmail.com/TestAPI2/DMWS.asmx?WSDL")
response = client.request(:CreateMailing) do
soap.body = {
Username: "Username",
Password: "Password",
ProductType: "A4Letter",
IsMono: false,
IsDuplex: true,
DespatchASAP: false,
DespatchDate: Time.parse("2012-04-09"),
AddressNameFormat: "Full Name",
ReturnFormat: "JSON"
}
end
The output looks like this
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:wsdl="https://www.cfhdocmail.com/LiveAutoAPI/" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ins0="https://www.cfhdocmail.com/LiveAutoAPI/">
<env:Body>
<ins0:CreateMailing>
<ins0:Username>Username</ins0:Username>
<ins0:Password>Password</ins0:Password>
<ins0:ProductType>A4Letter</ins0:ProductType>
<ins0:IsMono xsi:nil="true" />
<ins0:IsDuplex>true</ins0:IsDuplex>
<ins0:DespatchASAP xsi:nil="true" />
<ins0:DespatchDate>2012-04-09 00:00:00 +0200</ins0:DespatchDate>
<ins0:AddressNameFormat>Full Name</ins0:AddressNameFormat>
<ins0:ReturnFormat>JSON</ins0:ReturnFormat>
</ins0:CreateMailing>
</env:Body>
</env:Envelope>
But I want it to look like this.
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<CreateMailing xmlns="https://www.cfhdocmail.com/LiveAutoAPI/">
<Username>Username</Username>
<Password>Password</Password>
<ProductType>A4Letter</ProductType>
<IsMono/>true</IsMono>
<IsDuplex>true</IsDuplex>
<DespatchASAP>false</DespatchASAP>
<DespatchDate>2012-04-09 00:00:00 +0200</DespatchDate>
<AddressNameFormat>Full Name</AddressNameFormat>
<ReturnFormat>JSON</ReturnFormat>
</CreateMailing>
</soap:Body>
</soap:Envelope>
How do I do that?
I'm getting this error at the moment
Server did not recognize the value of HTTP Header SOAPAction: CreateMailing. (Savon::SOAP::Fault)

These changes solved my problem.
client.request(:web, "CreateMailer") do |soap|
soap.input = [
"CreateMailer", {
xmlns: "https://www.cfhdocmail.com/LiveAutoAPI/"
}
]
soap.element_form_default = :unqualified
soap.body = {
Username: "Username",
Password: "Password",
ProductType: "A4Letter",
IsMono: false,
IsDuplex: true,
DespatchASAP: false,
DespatchDate: Time.parse("2012-04-09"),
AddressNameFormat: "Full Name",
ReturnFormat: "JSON"
}
client.http.headers.delete("SOAPAction")
end
Thanks #sluukkonen for the help.

There might be a better way to do it, but the only way I could figure out how to get the XML body exactly how I needed it was to build my own XML. I have a to_xml method in my model and it gets called like soap.body = { to_xml }.
def to_xml
xml = Builder::XmlMarkup.new(indent: 2)
xml.instruct!
xml.Username "Username"
xml.Password "Password"
end
