Create payment notification webhooks

Webhooks are HTTP callbacks that receive notification messages for events. To receive webhook notifications for payment transactions, you must configure your webhook listener apps to receive notification messages for payment state changes and other events. You do this one time for each app.

Note: To test your webhook listener URI endpoints with mock webhook data, use the webhooks simulator.

To configure your listener apps to receive notification messages for payment state changes and other events:
1. Define webhook events to which you want to subscribe.
2. Create webhook.

Define webhook events

To subscribe your app to webhooks, create an object that contains the event_types, which are the webhook event names, and the url for your webhook listener to which you send those notifications.

var webhook_json = {
  url: 'https://f615ef32.ngrok.io',
  event_types: [{
    name: 'PAYMENT.SALE.COMPLETED'
  },{
    name: 'PAYMENT.SALE.DENIED'
  }]
};
$webhook = new \PayPal\Api\Webhook();

// Set webhook notification URL
$webhook->setUrl("https://f615ef32.ngrok.io");

// Set webhooks to subscribe to
$webhookEventTypes = array();
$webhookEventTypes[] = new \PayPal\Api\WebhookEventType(
  '{
    "name":"PAYMENT.SALE.COMPLETED"
  }'
);

$webhookEventTypes[] = new \PayPal\Api\WebhookEventType(
  '{
    "name":"PAYMENT.SALE.DENIED"
  }'
);

$webhook->setEventTypes($webhookEventTypes);
webhook = Webhook({
  "url": "https://f615ef32.ngrok.io",
  "event_types": [{
    "name": "PAYMENT.SALE.CREATED"
  },{
    "name": "PAYMENT.SALE.DENIED"
  }]
})
webhook = Webhook.new({
  :url => "https://f6153ef32.ngrok.io",
  :event_types => [{
    :name => "PAYMENT.PAYOUTS-ITEM.FAILED"
  },{
    :name => "PAYMENT.PAYOUTS-ITEM.HELD"
  }]
})
import java.util.ArrayList;
import java.util.List;

import com.paypal.api.payments.EventType;
import com.paypal.api.payments.Webhook;
import com.paypal.base.rest.APIContext;
import com.paypal.base.rest.PayPalRESTException;

List eventTypes = new ArrayList(); 
   
EventType eventType1 = new EventType(); 
eventType1.setName("VAULT.CREDIT-CARD.CREATED"); 

EventType eventType2 = new EventType(); 
eventType2.setName("VAULT.CREDIT-CARD.UPDATED"); 

eventTypes.add(eventType1); 
eventTypes.add(eventType2);

Webhook webhook = new Webhook(); 
webhook.setUrl("https://f6153ef32.ngrok.io"); 
webhook.setEventTypes(eventTypes);
public static Webhook GetNewWebhook(){
  return new Webhook{
    url = GetNewWebhookUrl(),
    event_types = new List{
      new WebhookEventType{
        name = "PAYMENT.SALE.CREATED"
      },
      new WebhookEventType{
        name = "PAYMENT.SALE.DENIED"
      }
    }
  };
}

Note: See webhook event names.

Create webhook

After you create the webhook definition object, call the webhook create method to create the webhook. The endpoint defined in the webhook starts receiving notifications when the events occur in the app.

paypal.notification.webhook.create(webhook_json, function (error, webhook) {
  if (error) {
    console.error(JSON.stringify(error.response));
    throw error;
  } else {
    console.log('Create webhook Response');
    console.log(webhook);
  }
});
try {
  $output = $webhook->create($apiContext);
} catch (PayPal\Exception\PayPalConnectionException $ex) {
  echo $ex->getCode();
  echo $ex->getData();
  die($ex);
} catch (Exception $ex) {
  die($ex);
}
if webhook.create():
  print("Webhook[%s] created successfully" % (webhook.id))
else:
  print(webhook.error)
begin
  webhook = webhook.create
  logger.info "Webhook[#{webhook.id}] created successfully"
rescue ResourceNotFound => err
  logger.error webhook.error.inspect
end
try{
  Webhook createdWebhook = webhook.create(apiContext, webhook);
  System.out.println("Webhook successfully created with ID " + createdWebhook.getId());
} catch (PayPalRESTException e) {
  System.err.println(e.getDetails());
}
var apiContext = Configuration.GetAPIContext();
var webhook = GetNewWebhook();

this.flow.AddNewRequest("Create webhook", webhook);
var createdWebhook = webhook.Create(apiContext);
