Help with SOAP

Question

Hi there,
Hoping to get some help here with an issue I'm stuck on.
I'm trying to use the Bing Ads Web service in Python (SUDS) and also just using curl.
I'm able to read in the WSDL file and generate the XML/SOAP output. 
I feel like there is something minor wrong, just not too sure or familiar with what it might be. 
Trying to call the following action:  DownloadCampaignsByAccountIds
I tried to mimic the documentation as much as possible: http://msdn.microsoft.com/en-US/library/jj885755.aspx#request_soap
Even copying and pasting the XML from the link above and adding my own values in after to make sure.
I have the XML generated in SUDS but I keep getting a 400 Error: HTTP failed - 400 - Bad Request
If I use curl and use the example provide as a template I get a slightly different error:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body><s:Fault>
<faultcode xmlns:a="http://schemas.microsoft.com/ws/2005/05/addressing/none">a:ActionNotSupported</faultcode>
<faultstring xml:lang="en-US">The message with Action '' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. 
This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a 
binding/security mismatch between the sender and the receiver.  
Check that sender and receiver have the same contract and the same binding 
(including security requirements, e.g. Message, Transport, None).
</faultstring></s:Fault></s:Body></s:Envelope> 
Here is my full XML I am trying to pass to the service:
<?xml version="1.0" encoding="UTF-8"?>

         </ns2:PerformanceStatsDateRange>

   </ns1:Body>
</SOAP-ENV:Envelope>
Any thoughts or ideas here? I feel like I am close...

Hello.
I made the following changes to your SOAP request to get it working. The final working request is pasted below.
1. Change i:nil to xsi:nil
2. Use 'ns2' or equivalent for the header elements e.g. ns2:UserName.
3. Specifiy DataScope as a space delimited list
4. Specify Entities as a space delimited list
5. Set last sync time to null, e.g. <ns2:LastSyncTimeInUTC xsi:nil="true" />
6. Remove custom date range, since you are requesting instead a Predefined time of Yesterday.
By the way, please also set LocationTargetVersion to Latest and use FormatVersion 3.0 which is the latest version.
