Starting April 15, 2025, all requests that send URLs with the HTTP protocol in the back_urls field will be automatically cleaned by the API, resulting in empty entries in our database. This change is due to the risks associated with the HTTP protocol, which lacks encryption and allows access to sensitive data. The cleaning process will be gradual, so starting May 15, 2025, requests with HTTP URLs will be completely blocked. We invite all our integrators to review their configurations and switch to other accepted protocols.

Starting June 30th, versions of PHP below 8.1 will no longer receive security fixes or development support. To ensure WooCommerce stores are not affected and continue receiving new features from Mercado Pago, it is essential to keep your version updated by that date.

In the status_detail field, related to the current payment status details from the Payments API, we have started to receive the new status rejected_by_biz_rule. This status indicates that the payment was declined due to business rules.

We have included the column "Data type (maximum length)" in the Glossary of the Released money and Account balance reports to indicate the data type associated with each field and the permitted format in each case.
