Webhooks - Notifications - Mercado Pago Developers

Webhooks

Webhook (also known as web callback) is a simple method that makes it easy for an app or system to provide real-time information whenever an event happens, that is, it is a way to passively receive data between two systems through of an HTTP POST.

Webhooks notifications can be configured for one or more applications created in your Dashboard.

Once configured, the Webhook will be sent whenever one or more registered events occur, avoiding a search job every minute in search of an answer and, consequently, a system overload and data loss whenever there is some situation. After receiving a notification on your platform, Mercado Pago will wait for a response to validate that you received it correctly

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

Configuration via Dashboard

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.

webhooks

  1. First, an application must be created on the home page of your Dashboard.
  2. With the application created, go to the Webhooks Notifications tab in your Dashboard and configure the URLs of production and test from which notifications will be received.
  3. You will also be able to experiment and test if the indicated URL is receiving notifications correctly, being able to verify the request, the response given by the server and the description of the event.
  4. If you need to identify multiple accounts, at the end of the indicated URL you can indicate the parameter ?customer=(sellername) endpoint to identify the sellers.
  5. Next, select the events from which you will receive notifications in json format via an HTTP POST to the URL specified above. An event is any type of update to the reported object, including status or attribute changes. See the events that can be configured in the table below.

shipmentsshipment.updatedShipping data and order update

Setup 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.
          
<?php
    require_once 'vendor/autoload.php';

    MercadoPago\SDK::setAccessToken("YOUR_ACCESS_TOKEN");

    $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'];

    $response = array(

using System;
using MercadoPago.Client.Common;
using MercadoPago.Client.Payment;

using MercadoPago.Resource.Payment;

MercadoPagoConfig.AccessToken = "YOUR_ACCESS_TOKEN";

var paymentRequest = new PaymentCreateRequest

            "email": "test@test.com"

          }
    }'


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

php

<?php
  MercadoPago\SDK::setAccessToken("ENV_ACCESS_TOKEN");
  switch($_POST["type"]) {
      case "payment":
          $payment = MercadoPago\Payment::find_by_id($_POST["data"]["id"]);
          break;
      case "plan":
          $plan = MercadoPago\Plan::find_by_id($_POST["data"]["id"]);
          break;
      case "subscription":
          $plan = MercadoPago\Subscription::find_by_id($_POST["data"]["id"]);
          break;
      case "invoice":
          $plan = MercadoPago\Invoice::find_by_id($_POST["data"]["id"]);
          break;
      case "point_integrartion_wh":
          // $_POST contains the information related to the notification.
          break;    
  }
?>
  1. Once the necessary settings have been made, the notification via Webhook will have the following format:
Important
For the event type point_integration_wh the notification format changes. Click here to consult the documentation of Mercado Pago Point.
In the case of the shipments event, we will also have some different attributes in the response. Check the table below for these features.

json

{
  "id": 12345,
  "live_mode": true,
  "type": "payment",
  "date_created": "2015-03-25T10:04:58.396-04:00",
  "user_id": 44444,
  "version": 1,
  "api_version": "v1",
  "action": "payment.created",
  "data": {
      "id": "999999999"
  }
}

This indicates that payment 999999999 was created for user 44444 in production mode with API version V1 and that this event occurred on date 2016-03-25T10:04:58.396-04 :00.

  1. If you want to receive notifications only from Webhook and not from IPN, you can add in the notification_url the parameter source_news=webhook. For example: https://www.yourserver.com/notifications?source_news=webhooks

Actions required after receiving 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 try5 minutes5 seconds
Second attempt45 minutes5 seconds
Third attempt6 hours5 seconds
Fourth attempt2 days5 seconds
Fifth attempt4 days5 seconds

After returning the notification and confirming its receipt, you will obtain the full information of the notified resource by accessing the corresponding API endpoint:

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