Solution for - Magento cart.totals API Returns Zero After Adding Product

Hello,

Recently in one of my project I was working with Magento SOAP APIs. Where we have used Magento cart.create API to create Magento cart and adding items to it. Now every time I add items I want to refresh totals. So I used cart_product.add API and after that used cart.totals API to get totals. But strangely it was always returning zero, no matter how many products are there. I tried to find out a solutions for it and did some tests and in one of the test I found out that if after creating a cart if I do operations like setting shipping address or add coupons, it was giving accurate totals.  That's really strange. I tried to find out issue for it but I am not magento expert to finally I came up with following solution. After creating  cart, I set dummy billing and shipping address immediately. And then when I add a product and get totals, it was giving me accurate result.

Please note this is not the best solution, but if you want to use you can use this. This will solve your problem. If any magento expert can debug API code and resolve this issue please post solution.

So here is what you have to do.

//Create a Quote

$client = new SoapClient($baseurl.'/api/soap/?wsdl');
$session = $client->login(USER,PASS);
$quote_id = $client->call( $session, 'cart.create', array($_storeId) );

//Add dummy shipping and billing address

$arrAddresses = array(
array(
"mode" => "shipping",
"firstname" => "testFirstname",
"lastname" => "testLastname",
"company" => "testCompany",
"street" => "testStreet",
"city" => "testCity",
"region" => "testRegion",
"postcode" => "testPostcode",
"country_id" => "id",
"telephone" => "0123456789",
"fax" => "0123456789",
"is_default_shipping" => 0,
"is_default_billing" => 0
),
array(
"mode" => "billing",
"firstname" => "testFirstname",
"lastname" => "testLastname",
"company" => "testCompany",
"street" => "testStreet",
"city" => "testCity",
"region" => "testRegion",
"postcode" => "testPostcode",
"country_id" => "id",
"telephone" => "0123456789",
"fax" => "0123456789",
"is_default_shipping" => 0,
"is_default_billing" => 0
)
);
$resultCustomerAddresses = $client->call($session, "cart_customer.addresses", array($quote_id, $arrAddresses));


//Now add a product to cart

$resultCartProductAdd = $client->call(
$session,
"cart_product.add",
array(
$quote_id,
$arrProducts
)
);

//Now get the cart info

$result = $client->call($session, 'cart.totals', $quote_id);
echo json_encode($result);

Hope this helps you and solve your problem.
