Implement 3DS

Add 3DS to your payment strategy.

Enable 3DS from DEUNA Admin

To enable 3DS in Admin:

1. Go to the Connections section in the admin.
2. Select the processor to activate.

3. Enter the respective credentials.
4. Check the Enable security methods box
5. Select the type of 3DS:
   • Enable DEUNA 3DS: Enables DEUNA's internal 3DS
   • Enable processor 3DS: Enables the payment processor's external 3DS
6. Click Connect.

Validate 3DS

To validate if a processor has 3DS active:

1. Go to Connections.
2. Search for the processor.
3. Click on the three dots in the upper right corner of the processor.
4. Click edit.
5. Verify the 3DS in the processor detail.

Configure DEUNA's 3DS MPI

To use 3DS MPI, provide the following information for each processor:

• Merchant ID (Affiliation Number): This is the merchant identifier registered with the acquirer that will be used to process this connection.
• Acquirer's BIN configured by the merchant: Bank Identification Number (BIN), issued by the merchant's bank or processor.
• Merchant name: Your store name in the processor.
• MCC (Merchant Category Code): Example of where to get the value: https://www.mastercard.us/content/dam/public/mastercardcom/na/global-site/documents/quick-reference-booklet-merchant.pdf
• Merchant/store URL
• Country where you operate

Configure the 3DS display strategy

Once 3DS is enabled, you can define how it will be displayed to the end user. Traditionally, transactions that required a 3DS challenge were handled through a full-screen redirect. With DEUNA, it's now possible to show the embedded 3DS authentication flow in the following products when the issuer allows it:

1. Payment link: Through a modal containing a modal with the 3DS challenge.

   
   

2. Payment widget for CC/DC and ClickToPay: Integrated directly into the widget, using an iFrame.

   
   

👍

With DEUNA's 3DS MPI you can always configure it to display embedded to preserve the user experience within the payment link or Payment widget environment, avoiding tab changes and enhancing conversion.

1. An the Admin, go to Store.
2. navigate to the new "Widget customization" tab.
3. You'll see an option to select the type of 3DS experience.

Currently supported integrations for Payment Link and Payment Widget are summarized as follows:
