How add notify url to REST API paypal? - php

Question

I created simple payment in paypal
$payer = new Payer();
$payer->setPaymentMethod("paypal");
$item1 = new Item();
$item1->setName('some name')
->setCurrency('USD')
->setQuantity(1)
->setSku("my id product")
->setPrice(11);
$itemList = new ItemList();
$itemList->setItems(array($item1));
$amount = new Amount();
$amount->setCurrency("USD")
->setTotal(11);
$transaction = new Transaction();
$transaction->setAmount($amount)
->setItemList($itemList)
->setDescription("Payment description")
->setInvoiceNumber(uniqid());
$baseUrl = "https://my_site_address.com";
$redirectUrls = new RedirectUrls();
$redirectUrls->setReturnUrl("$baseUrl/ExecutePayment/?success=true")
->setCancelUrl("$baseUrl/ExecutePayment/?success=false");
$payment = new Payment();
$payment->setIntent("sale")
->setPayer($payer)
->setRedirectUrls($redirectUrls)
->setTransactions(array($transaction));
$request = clone $payment;
try {
$payment->create($apiContext);
} catch (Exception $ex) {
print_r($ex);
exit(1);
}
$approvalUrl = $payment->getApprovalLink();
print_r($approvalUrl);
After execute this code everything is alright, I am redirected to Paypal sandbox and after log in i can make a pay. But I don't know how, where i can set my notify_url?
Anyone can help ?

Answer 1

the direct and short answer to your question is yes you can set a "notifyUrl" via REST API:
$transaction = new Transaction();
$transaction->setAmount($amount)
->setItemList($itemList)
->setDescription(" ...... ")
->setNotifyUrl("your notifyUrl here")
->setInvoiceNumber($invoiceNo);
BUT this is not the correct way receiving REST Notifications. Use "Webhooks" instead (though Webhooks using PHP is soo hacky, but at the end you find a solution. if you need more details on how to do it, just comment this answer).
Back to NotofyUrl:
for testing i was able to receive notifications via notifyUrl, BUT after implementing a webhook, PayPal still sending notifications to my old already removed NotifyUrl for every new Payment. i deleted it from the code, i deactivated IPN in my PayPal account. I tried many things, but PayPal still sending IPNs for every Payment. Now i receive 2 Notofications, one via NofityUrl and the second via WebhookEvent Listener. no idea whats going wrong here. So i wouldn't recommend the usage of notifyUrl, instead just implement a webhookEvent listener.

Answer 2

The parameter for notify url can't be used in REST API calls. If you want to set up the IPN url, you have to set it within your Paypal account:
Here is the steps:
1. Login paypal account
2. Click profile and under Selling preferences, choose Instant Payment Notification preferences
3. Click Choose IPN setting
4. Type the URL that you receive IPN message and choose Enabled
