From now on, the user ID fields, which were previously of type Int32, have changed to the Int64 format. If your application uses this information through fields such as ‘user_id’, ‘payer_id’, ‘collector_id’, or any other reference to user IDs provided by Mercado Pago, your integration may generate errors if you do not make the necessary adjustments. See more details here.

We inform you that the integration with Mercado Pago is not compatible with the Store Credit feature of the Shopify platform.

It is important to highlight that although Internet Explorer 11* is no longer officially supported by Mercado Pago, the browser is still compatible with some flows of the Checkout API.

We added a new example for the topic "Chargebacks" on Webhooks notifications. Go to Additional information about notifications to check this update.
