Paypal CC Direct Payment error - paypal

Question

I need some help to figure out paypal's API, all I'm trying to do is run a cc charge to my sandbox account, I've been looking at their documentation and code samples but I just can't find the right information right now, like where to add the sandbox endpoint. So, when I run the function below I get the following error:
string(213) "{"name":"MALFORMED_REQUEST","message":"Incoming JSON request does not map to API request","information_link":"https://developer.paypal.com/webapps/developer/docs/api/#MALFORMED_REQUEST","debug_id":"6eb15180f8d92"}"
This is the function I'm calling:
public static function ccPayment($paymentInfo, $credentials)
{
$apiContext = new \PayPal\Rest\ApiContext(
new \PayPal\Auth\OAuthTokenCredential(
$credentials['clientId'],
$credentials['secret']
)
);
$card = new CreditCard();
$card->setType("visa")
->setNumber("xxxxxxxxxxxxxxxx")
->setExpireMonth("11")
->setExpireYear("2019")
->setCvv2("012")
->setFirstName("Joe")
->setLastName("Shopper");
$fi = new FundingInstrument();
$fi->setCreditCard($card);
$payer = new Payer();
$payer->setPaymentMethod("credit_card")
->setFundingInstruments(array($fi));
$item1 = new Item();
$item1->setName('Ground Coffee 40 oz')
->setDescription('Ground Coffee 40 oz')
->setCurrency('USD')
->setQuantity(1)
->setTax(0.3)
->setPrice(7.50);
$itemList = new ItemList();
$itemList->setItems(array($item1));
$transaction = new Transaction();
$transaction->setAmount(489)
->setItemList($itemList)
->setDescription("Payment description")
->setInvoiceNumber(uniqid());
$payment = new Payment();
$payment->setIntent("sale")
->setPayer($payer)
->setTransactions(array($transaction));
// $request = clone $payment;
try
{
$payment->create($apiContext);
}
catch (Exception $ex)
{
dd($ex->getData());
}
dd($paymentInfo);
}
Been coding since the morning so I need another set of eyes right now because I just can't see what I'm doing wrong. I will appreciate any help.
PS. Apologies if it's something dumb. Eg. a missing comma.
Thanks.

Got it working !! Here's the working code:
$apiContext = new \PayPal\Rest\ApiContext(
new \PayPal\Auth\OAuthTokenCredential(
$credentials['clientId'],
$credentials['secret']
)
);
$apiContext->setConfig(
array(
'log.LogEnabled' => true,
'log.FileName' => '../app/storage/paypal/PayPal.log',
'log.LogLevel' => 'FINE'
)
);
$card = new CreditCard();
$card->setType("visa")
->setNumber("xxxxxxxxxxxxxxxxx")
->setExpireMonth("11")
->setExpireYear("2019")
->setCvv2("012")
->setFirstName("Joe")
->setLastName("Shopper");
$fi = new FundingInstrument();
$fi->setCreditCard($card);
$payer = new Payer();
$payer->setPaymentMethod("credit_card")
->setFundingInstruments(array($fi));
$item1 = new Item();
$item1->setName('Ground Coffee 40 oz')
->setDescription('Ground Coffee 40 oz')
->setCurrency('USD')
->setQuantity(1)
->setPrice(49.99);
$itemList = new ItemList();
$itemList->setItems(array($item1));
$details = new Details();
$details->setSubtotal(49.99);
$amount = new Amount();
$amount->setCurrency("USD")
->setTotal(49.99)
->setDetails($details);
$transaction = new Transaction();
$transaction->setAmount($amount)
->setItemList($itemList)
->setDescription("Payment description")
->setInvoiceNumber(uniqid());
$payment = new Payment();
$payment->setIntent("sale")
->setPayer($payer)
->setTransactions(array($transaction));
try
{
$payment->create($apiContext);
}
catch (Exception $ex)
{
dd($ex->getData());
}
dd($payment);
I was missing new Amount & new Details. Also, for the sake of documentation, your monetary totals must add up. Eg. tax, subtotal, total.
