SOAP requests using Savon - ruby

Question

I dug as deep as I could but could not find a solution to my problem:
I want to send SOAP requests to ExactTarget API. I am trying to use Savon, but the requests it creates are different from those that worked with ExactTarget's API (I used Java previously) and in the end I get an error when running the Ruby script.
Below is the body of a working request that I am to create in Ruby:
<S:Body>
<RetrieveRequestMsg xmlns="http://exacttarget.com/wsdl/partnerAPI">
<RetrieveRequest>
<ObjectType>BounceEvent</ObjectType>
<Properties>SendID</Properties>
<Properties>SubscriberKey</Properties>
<Properties>EventDate</Properties>
<Properties>SMTPCode</Properties>
<Properties>BounceCategory</Properties>
<Properties>SMTPReason</Properties>
<Properties>BounceType</Properties>
<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="SimpleFilterPart">
<Property>SendID</Property>
<SimpleOperator>equals</SimpleOperator>
<Value>421939</Value>
</Filter>
</RetrieveRequest>
</RetrieveRequestMsg>
</S:Body>
Now here is the code I created in Ruby:
client = Savon.client do
wsdl 'https://webservice.s4.exacttarget.com/etframework.wsdl'
wsse_auth("user", "pass")
end
builder = Builder::XmlMarkup.new
builder.instruct!(:xml, encoding: "UTF-8")
#builder.RetrieveRequestMsg('xmlns'=>'http://exacttarget.com/wsdl/partnerAPI') do
builder.RetrieveRequest do
builder.ObjectType "BounceEvent"
builder.Properties "SendID"
builder.Properties "SubscriberKey"
end
#end
theBody = builder.target!
theBody.slice! '<?xml version="1.0" encoding="UTF-8"?>'
client.call(:retrieve, message: theBody)
..and here is the resulting request body:
<env:Body>
<tns:RetrieveRequestMsg>
<RetrieveRequest>
<ObjectType>BounceEvent</ObjectType>
<Properties>SendID</Properties>
<Properties>SubscriberKey</Properties>
</RetrieveRequest></tns:RetrieveRequestMsg>
</env:Body>
...and here is the resulting error I get:
<soap:Body>
<RetrieveResponseMsg xmlns="http://exacttarget.com/wsdl/partnerAPI">
<OverallStatus>Error</OverallStatus>
<RequestID>5ce5cfae-85b4-4e76-b9dd-299e9a9ca871</RequestID>
</RetrieveResponseMsg>
</soap:Body>
Any help is greatly appreciated!

Rather than using Builder, try using Savons call method for generating a SOAP request.
ruby
response = client.call(:authenticate, message: { username: "luke", password: "secret" })
You have the wsdl, so you should be able to determine the method name and arguments. Calling .operations on the client will list all of the available operations that you can generate.
