SOAP request works on PHP but not working on Ruby (gem: Savon2)

Question

I am trying to perform SOAP request called DoProduct. This method is updating specific product. I looked through WSDL ( http://api.istore.pl/#op.idp182160 ) and found out that I need one Product object and session key.

Everything working perfectly with PHP:

    $product = $soap->__soapCall("getProduct", array("sessionId" => $key, "productId" => $id));
    $result = $soap->__soapCall("doProduct", array("sessionId" => $key, "product" => $product));

I tried the same approach with Ruby (first get product, then send it back):

    product = client.call(:get_product, message: {:session_id => session_key, :product_id => id})
    response = @@client.call(:do_product, message: {:session_id => session_key, :product =>  product.hash[:envelope][:body][:get_product_response][:return]})

Ruby version is not working. I am receiving error that one parameter was not send (of course that parameter is there, I've checked hash from first response):

    HTTPI POST request to api.istore.pl (net_http)

Ruby Savon response.to_hash object (sorry for formatting, but I dont have any idea how to format it from console properly): http://pastie.org/7065887

Additionaly ruby response.to_json (formatting is better):

Does any one could give me any hint?

Answer 1

According to the SOAP response, you are in fact missing a parameter the SOAP service is expecting.

I notice with the PHP version you are just sending the entire product object, but in the Ruby version you are digging into the response hash.

Can you inspect 'product' in both versions and post the response here?
