How to prevent fraud in card payments

The Mercado Pago Antifraude Plus is an add-on for Mercado Pago Cards that optimizes security validation and maintains high approval rates, adding more security by identifying the device ID of buyers and preventing fraud and chargebacks.

The app uses 3DS 2.0 (3-D Secure) technology to authenticate credit card transactions before completing the payment, verifying whether the person making the purchase is actually the cardholder or has access to the cardholder's accounts. Check 3DS 2.0 for more information on how this type of authentication works.

To install Mercado Pago Antifraude Plus, follow the steps below.

  1. Access the Mercado Pago Antifraude Plus app page in the "Marketplace" and click on Install. If you haven't done so already, log in with your Shopify account.
  2. Carefully read the information about the requested permissions and click on Install again.
  3. If you have already installed the Mercado Pago Cards app, you do not need to enter your credentials again, but you can change them if necessary.
Important
Remember that, when changing the Shopify password, it is necessary to renew your credentials. To do so, follow the instructions in the Best practices for credentials documentation. Then, to update them on your Shopify account, click on Manage account and fill in the corresponding fields with your access_token and public_key being careful not to swap the fields when copying and pasting the credentials.
  1. Finally, click on the Verify activation option of Mercado Pago Antifraude Plus, go to the "Settings" section of Shopify and click on Save to enable the app and complete the installation.

That's it! Mercado Pago Antifraude Plus has been successfully installed!
