Webhooks is a type of notification that allows 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.

It uses HTTP REST, instantly notifies updates, and brings more security to its integration through a secret signature, a validation method to ensure that received notifications were sent by Mercado Pago.

In order to provide more security for those who integrate with Mercado Pago's solutions and allow more dynamism to test the sending of their Webhooks alerts, two new features have been released on the configuration screen of these notifications.

The secret signature is a validation method to ensure that received notifications were sent by Mercado Pago. The signature is automatically generated after configuring the URLs and Events and will always be sent in Mercado Pago's Webhooks notifications to guarantee authenticity and prevent fraud.

With the notifications simulator, it is now possible to simulate the receipt of various types of Webhooks notifications in addition to payment ones, such as in-person integrations, fraud alerts, plans and subscriptions, among others. This way, those who integrate with Mercado Pago will have an easier time mapping and programming all existing scenarios.
