Piwik Bulk API Request

I am trying to use the bulk API request for php, but I can't find any examples or get it to work. I can get it to work over the REST API, but I can't get it to convert. Here are the two requests I am trying to make for demonstration.



$request = new Piwik_API_Request('
method=API.getPiwikVersion&format=json&token_auth=xxx&
method=API.getLogoUrl&format=json&token_auth=xxx');


$result = $request->process();
echo $result;
