To add support for 3DS (security protocol that allows buyers to be authenticated by the issuing bank) in the Adyen integration, you must configure the connector first. Follow the steps below:

1. In the VTEX Admin, go to Store Settings > Payment > Settings, or type Settings in the search bar at the top of the page.
2. Access the Gateways Affiliations tab.
3. Click on the Adyen affiliation card.
4. Go to Live Endpoint URL Prefix and follow this Adyen tutorial to get the necessary information.
5. In the field Enable 3D Secure?, select Yes.
6. Choose the 3DS mode — 3DS, 3DS2, or 3DS2 Data only — defined in the agreed-upon business partnership with Adyen.
7. Fill in the remaining fields according to this tutorial.
8. Click on Save.

After configuring the connector on VTEX, go to the Adyen dashboard to enable 3DS for your store transactions.

We recommend that you set up the test environment before moving to the live environment. Validate the settings in the test environment, then access the Live environment to make final adjustments.

1. Click on the links below to access Adyen's test and live environments:

   • Adyen's test environment: https://ca-test.adyen.com/ca/ca/login.shtml
   • Adyen's live environment: https://ca-live.adyen.com/ca/ca/login.shtml

2. Click on Risk and then click Dynamic 3D Secure.

3. Click on Create new rule to create a new 3DS activation rule. Check out this Adyen documentation for more details.

4. After creating the rule, click on Save.

Once you have completed these steps, the 3DS security module will be ready to be used in your Adyen integration.
