Check the first steps


The IPN (Instant Payment Notification) is a mechanism that allows your application to receive notifications from Mercado Pago informing the status of a certain payment, chargeback and merchant_order, through a call HTTP POST to inform about your transactions.

In IPN notifications, only one notification URL can be configured per account (depending on the application, more than one application can use this URL). In addition, there is also the possibility of using this type of notification from the object's notification_url field, so the URL can be different for each object or application.

In this documentation, we will explain the necessary settings for receiving IPN notifications (through the Dashboard or when creating payments), as well as showing the necessary actions that you must take for Mercado Pago to validate that the messages were properly received.

URLs and events configuration

Below we will explain how to indicate the URLs that will be notified and how to configure the events for which notification will be received.


  1. If you haven't done so already, create an application in the developer Dashboard.
  2. Once the application is created, navigate to the IPN section on the Application Details page.
  3. Next, configure the production URL where the notifications will be received.
  4. If you need to identify multiple accounts, at the end of the indicated URL you can specify the parameter ?customer=(sellername) endpoint to identify the sellers.
  5. Select the events from which you will receive notifications in json format using HTTP POST to the URL specified above. We notify you of events related to your orders (merchant_orders), chargebacks received (chargebacks), payments received (payment), payment attempts (point_integration_ipn) ou fraud alerts (delivery_cancellation).

Configuration while creating payments

It is possible to configure the notification URL more specifically for each payment using the notification_url field. See below how to do this using the SDKs.

  1. In the notification_url field, indicate the URL from which notifications will be received, as shown below.
   require_once 'vendor/autoload.php';


   $payment = new MercadoPago\Payment();
   $payment->transaction_amount = (float)$_POST['transactionAmount'];
   $payment->token = $_POST['token'];
   $payment->description = $_POST['description'];
   $payment->installments = (int)$_POST['installments'];
   $payment->payment_method_id = $_POST['paymentMethodId'];
   $payment->issuer_id = (int)$_POST['issuer'];
   $payment->notification_url = `http://requestbin.fullcontact.com/1ogudgk1`;
   $response = array(
       'status' => $payment->status,
       'status_detail' => $payment->status_detail,
       'id' => $payment->id
   echo json_encode($response);


var mercadopago = require('mercadopago');

≈    });
 .catch(function(error) {


Payment payment = new Payment();

Identification identification = new Identification();

Payer payer = new Payer();



require 'mercadopago'

         "payer": {
           "email": "test@test.com"


  1. Implement the notifications receiver using the following code as an example:


  $merchant_order = null;
  switch($_GET["topic"]) {
      case "payment":
          $payment = MercadoPago\Payment::find_by_id($_GET["id"]);
          // Get the payment and the corresponding merchant_order reported by the IPN.
          $merchant_order = MercadoPago\MerchantOrder::find_by_id($payment->order->id);
      case "merchant_order":
          $merchant_order = MercadoPago\MerchantOrder::find_by_id($_GET["id"]);
  $paid_amount = 0;
  foreach ($merchant_order->payments as $payment) { 
      if ($payment['status'] == 'approved'){
          $paid_amount += $payment['transaction_amount'];
   // If the payment's transaction amount is equal (or bigger) than the merchant_order's amount you can release your items
  if($paid_amount >= $merchant_order->total_amount){
      if (count($merchant_order->shipments)>0) { // The merchant_order has shipments
          if($merchant_order->shipments[0]->status == "ready_to_ship") {
              print_r("Totally paid. Print the label and release your item.");
      } else { // The merchant_order don't has any shipments
          print_r("Totally paid. Release your item.");
  } else {
      print_r("Not paid yet. Do not release your item.");
  1. After the configurations are completed, Mercado Pago will notify this URL with two parameters every time a resource is created or updated:
topicIdentifies what the resource is, it can be payment, chargebacks, merchant_order or point_integration_ipn.
idIt is a unique identifier of the notified resource.
For example, if you set the URL: https://www.yoursite.com/notifications, you will receive payment notifications like this: https://www.yoursite.com/notifications?topic=payment&id=123456789.
  1. If you want to receive notifications only from IPN and not from Webhooks, you can add in the notification_url the parameter source_news=ipn. For example: https://www.yourserver.com/notifications?source_news=ipn.

After receiving the notification

When you receive a notification on your platform, Mercado Pago waits for a response to validate that you received it correctly. For that, you must return an HTTP STATUS 200 (OK) or 201 (CREATED). If this response is not sent, it will be understood that you have not received the notification and a further attempt to send it will be made until you submit the response.

In the table below you can find the main events, deadlines and waiting time for receiving new notification attempts.

EventDeadline after the first dispatchConfirmation waiting time
Shipping-22 seconds
First try15 minutes5 seconds
Second attempt30 minutes5 seconds
Third attempt6 hours5 seconds
Fourth attempt48 hours5 seconds
Fifth attempt96 hours5 seconds

After returning the notification, you will get the full information of the notified resource by going to the corresponding API endpoint:

paymenthttps://api.mercadopago.com/v1/payments/[ID]check documentation
chargebackshttps://api.mercadopago.com/v1/chargebacks/[ID]check documentation
merchant_ordershttps://api.mercadopago.com/merchant_orders/[ID]check documentation

Also, specifically in fraud alerts, the order must not be delivered and the cancellation needs to be done through the cancellations API.

In the notification, you will receive a JSON with the following information containing the payment id to cancel.


 "description": ".....",
 "merchant_order": 4945357007,
 "payment_id": 23064274473

You can also get more order information using the Get order API.

With this information, you will be able to carry out the necessary updates to your platform, such as updating an approved payment or a closed order.
