Receive Payment Notifications
IPN (Instant Payment Notification) notifications are the automatic form of notice of the creation of new payments and updates of their status. For example if they were approved, rejected or if they are pending. They allow you to manage your stock and keep your system in sync.
Additional information for the preference
Improve the approval of payments and the experience of your buyers by adding information in your preference.
We recommend detailing all possible information about the item and the buyer.

item in the following link. If you cannot find the category of your product, send the value others as category_id.Return URL
At the end of the payment process you have the option to redirect the buyer to your website. In order to do this you need to add the back_urls attribute and define where you want the return to site button to redirect the buyer depending on the payment status.
If you want this redirection to be made automatically you need to also add the auto_return attribute with value approved.
auto_return only works for redirect and mobile mode. It does not work for modal mode since the buyer stays on your website.
| Attribute | Description |
|---|---|
auto_return | Automatically redirect to your site when the payment is successful. Possible value is approved. |
back_urls | success. Return URL for approved payment.pending. Return URL for pending payment.failure. Return URL for canceled payment. |
Through the back_urls the following parameters will return:
| Parameter | Description |
|---|---|
payment_id | Payment ID of Mercado Pago. |
status | Payment status. For example: approved for an approved payment or pending for a pending payment. |
external_reference | Value that you sent when creating the payment preference. |
merchant_order_id | Payment order ID created in Mercado Pago. |
back_urls of failure.

Prevent payment rejection
A payment can be rejected because the issuer for the selected method detected a problem or because of non-compliance with security requirements.
Avoid rejected payments with our recommendations and improve the approval process.
Cancellations and Returns
Cancellations are made when the cash payment was not completed before the expiration date and the seller decides to cancel it. And the returns happen when the payment was made but the seller decides to cancel it totally or partially.
You can find all the information in the Returns and Cancellations section.
Manage Chargebacks
A chargeback occurs when the buyer contacts the entity that issued the card and communicates that they do not recognize the payment. This means that the seller's money for that payment will be withheld from their Mercado Pago account until it is settled.
