Create Webhook Sample

This sample code demonstrate how you can create a webhook, as documented here at: https://developer.paypal.com/webapps/developer/docs/api/#create-a-webhook API used: POST /v1/notifications/webhooks

require __DIR__ . '/../bootstrap.php';

Create a new instance of Webhook object

$webhook = new \PayPal\Api\Webhook();

Basic Information

{
    "url":"https://requestb.in/10ujt3c1",
    "event_types":[
       {
           "name":"PAYMENT.AUTHORIZATION.CREATED"
       },
       {
           "name":"PAYMENT.AUTHORIZATION.VOIDED"
       }
    ]
 }

Fill up the basic information that is required for the webhook The URL should be actually accessible over the internet. Having a localhost here would not work.

There is an open source tool http://requestb.in/ that allows you to receive any web requests to a url given there.

NOTE: Please note that you need an https url for paypal webhooks. You can however override the url with https, and accept

any warnings your browser might show you. Also, please note that this is entirely for demo purposes, and you should not be using this in production

$webhook->setUrl("https://requestb.in/10ujt3c1?uniqid=" . uniqid());

Event Types

Event types correspond to what kind of notifications you want to receive on the given URL.

$webhookEventTypes = array(); $webhookEventTypes[] = new \PayPal\Api\WebhookEventType( '{ "name":"PAYMENT.AUTHORIZATION.CREATED" }' ); $webhookEventTypes[] = new \PayPal\Api\WebhookEventType( '{ "name":"PAYMENT.AUTHORIZATION.VOIDED" }' ); $webhook->setEventTypes($webhookEventTypes);

For Sample Purposes Only.

$request = clone $webhook;

Create Webhook

try { $output = $webhook->create($apiContext); } catch (Exception $ex) {

// Ignore workflow code segment

// Ignore workflow code segment if ($ex instanceof \PayPal\Exception\PayPalConnectionException) { $data = $ex->getData(); ResultPrinter::printError("Created Webhook Failed. Checking if it is Webhook Number Limit Exceeded. Trying to delete all existing webhooks", "Webhook", "Please Use <a style='color: red;' href='DeleteAllWebhooks.php' >Delete All Webhooks</a> Sample to delete all existing webhooks in sample", $request, $ex); if (strpos($data,'WEBHOOK_NUMBER_LIMIT_EXCEEDED') !== false) { require 'DeleteAllWebhooks.php'; try { $output = $webhook->create($apiContext); } catch (Exception $ex) { ResultPrinter::printError("Created Webhook", "Webhook", null, $request, $ex); exit(1); } } else { ResultPrinter::printError("Created Webhook", "Webhook", null, $request, $ex); exit(1); } } else { ResultPrinter::printError("Created Webhook", "Webhook", null, $request, $ex); exit(1); }

Print Success Result

} ResultPrinter::printResult("Created Webhook", "Webhook", $output->getId(), $request, $output); return $output;
