Hello,
According to the documentation you provided, MangoPay is updating its API to support the 3DS2 protocol, which is intended to provide stronger security for online transactions. https://www.hebpartnernet.org/
If your website uses MangoPay to process payments, you may need to update your integration to support the new 3DS2 protocol. It is recommended that you review the documentation carefully and reach out to MangoPay support or your plugin provider for guidance on how to ensure compliance with the updated API.
I hope this information may useful for you.
