I have been trying to implement split payments using the Paypal Adaptive Payments API. I have got a simple parallel payment to work, however this shows both split payments to the buyer.
Basically I am selling a membership. Our local association should get 75% of the funds and 25% is passed on to the governing body. The member should only see the total amount as being a 2015 membership so I started to look into chained payments instead. This on the face of it looks like a very simple code change but is causing me issues in relation to unilateral payments.
I am implementing this in php.
So here is the paypal send method
function PaypalSend($payment_details, $api_function){
// initial endpoint that starts the transaction
$paypalInitialEndpoint = 'https://svcs.sandbox.paypal.com/AdaptivePayments/';
// set http headers
$headers = array(
'Connection: Close',
'X-PAYPAL-SECURITY-USERID: testseller_api1.nipf.com',
'X-PAYPAL-SECURITY-PASSWORD: 1381912839',
'X-PAYPAL-SECURITY-SIGNATURE: AzykGe5AzfK.mJFMRzBwIcTap-LcAsmsP4AhYzk1Y-07mh-xPLc-goK3',
'X-PAYPAL-APPLICATION-ID: APP-80W284485P519543T',
'X-PAYPAL-REQUEST-DATA-FORMAT: JSON',
'X-PAYPAL-RESPONSE-DATA-FORMAT: JSON'
);
// setup curl request and http headers
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $paypalInitialEndpoint . $api_function);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($payment_details));
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
if(!($res = curl_exec($ch)) )
{
error_log(curl_error($ch));
curl_close($ch);
exit;
}
curl_close($ch);
return json_decode($res, TRUE);
}
And here is my chained payment method. This code needs a lot of refactoring but was fully functional with the parallel payments with only minor changes to this current code.
function sendChainedPayment(){
$purchase_details_array = array(
"actionType" => "PAY",
"currencyCode" => "GBP",
"feesPayer" => "PRIMARYRECEIVER",
"memo" => "blah blah blah",
"receiverList" => array(
"receiver" => array(
array(
"amount" => "30.00",
"email" => "testseller@nipf.com",
"primary" => "true"
),
array(
"amount" => "10.00",
"email" => "testseller@gbpf.com",
"primary" => "false"
)
)
),
"returnUrl" => "http://localhost/membershipSuccess.php",
"cancelUrl" => "http://localhost/membershipCancel.php",
"requestEnvelope" => array(
"errorLanguage" => "en_UK",
"detailLevel" => "ReturnAll"
)
);
$response = PaypalSend($purchase_details_array, "Pay");
//echo json_encode($response) . "<br /><br />";
$payKey = $response['payKey'];
$payment_details = array(
"requestEnvelope" => array(
"errorLanguage" => "en_UK",
"detailLevel" => "ReturnAll"
),
"payKey" => $payKey,
"receiverOptions" => array(
array(
"receiver" => array("email" => "testseller@nipf.com"),
"invoiceData" => array(
"item" => array(
array(
"name" => "Membership 2015",
"price" => "30.00",
"identifier" => "Membership 2015: joe bloggs"
)
)
)
),
array(
"receiver" => array("email" => "testseller@gbpf.com"),
"invoiceData" => array(
"item" => array(
array(
"name" => "Membership 2015 (Fee)",
"price" => "10.00",
"identifier" => "Membership 2015 (Fee): joe bloggs"
)
)
)
)
)
);
$response = PaypalSend($payment_details, "SetPaymentOptions");
//echo json_encode($response) . "<br /><br />";
$paypalCustomerUrl = 'https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_ap-payment&paykey=' . $payKey;
echo $paypalCustomerUrl;
//header('Location: ' . $paypalCustomerUrl);
}
I am getting the following response JSON with the first callout. I think this is to do with the accounts being just sandbox accounts rather than real accounts but how am I meant to test this in the sandbox if the accounts all have to be real accounts? In this case the account used as the API account is the primary receiver.
