Payee account is invalid. #PAYEE_ACCOUNT_INVALID - paypal

Question

I am trying to implement PayPal Credit card functionality on Laravel for Rest Api. I am receiving the "PAYEE_ACCOUNT_INVALID" error. Any idea what am I doing wrong? Any help would be really appreciated.
I've tried with different test card numbers provided by PayPal via card generator mock.
Thanks.
This is my code snippet.
public function payment()
{
$gateway = Omnipay::create('PayPal_Rest');
// Initialise the gateway
$gateway->initialize(array(
'clientId' => env('PAYPAL_SANDBOX_CLIENT_ID'),
'secret' => env('PAYPAL_SANDBOX_CLIENT_SECRET'),
'testMode' => true,
));
#### Direct Credit Card Payment
// Create a credit card object
// DO NOT USE THESE CARD VALUES -- substitute your own
// see the documentation in the class header.
$card = new CreditCard([
'firstName' => 'Example',
'lastName' => 'User',
'number' => '4111111111111111',
'expiryMonth' => '01',
'expiryYear' => '2027',
'cvv' => '123',
]);
// Do a purchase transaction on the gateway
try {
$transaction = $gateway->purchase([
'amount' => '1.00',
'currency' => 'AUD',
'description' => 'This is a test purchase transaction.',
'card' => $card,
]);
$response = $transaction->send();
$data = $response->getData();
echo "Gateway purchase response data == " . print_r($data, true) . "\n";
if ($response->isSuccessful()) {
echo "Purchase transaction was successful!\n";
}
} catch (Exception $e) {
echo "Exception caught while attempting authorize.\n";
echo "Exception type == " . get_class($e) . "\n";
echo "Message == " . $e->getMessage() . "\n";
}
}

Answer 1

Payee account invalid means the receiving account cannot process the transaction. Most likely this is a deprecated integration method, although it is hard to say without seeing the actual API request and response.
The current way to process credit cards is with the PayPal Checkout SDK, which has a black debit or credit card button that expands a form on your site. Optionally there is an Advanced integration that can be added on for presenting the card fields in a more customized way; it's more work to implement.
