Device Data

The card issuer uses Device Data Collection (DDC) to fingerprint the customer's device.

Along with the risk data in the authentication request, it's used to decide if a challenge is needed or if the authentication can be frictionless (no challenge displayed to your customer). This step is required for the authentication to use 3DS2.

Device data initialization

POST your device data initialization request to the 3ds:deviceDataInitialize action link.

This request creates a JSON Web Token (JWT) that is used as part of the Device Data Collection (DDC) form. The DDC form also requires the first six digits of your customer's card number (BIN). The BIN can be returned if a token resource is provided, see JWT + BIN (token) request.

For consistency of integration you can also provide the full card number JWT + BIN (card). It will be truncated to become the BIN in the response.

Device data initialization example request

POST https://try.access.worldpay.com/verifications/customers/3ds/deviceDataInitialization

{
    "transactionReference": "unique-transactionReference",
    "merchant": {
        "entity": "default"
    }
}

Parameter Mandatory Description

transactionReference ✅ A unique reference for device data JWT request. for example, e-commerce order code.

merchant.entity ✅ Used to route the request in Access Worldpay, created as part of on-boarding.

Parameter	Mandatory	Description
`transactionReference`	✅	A unique reference for device data JWT request. for example, e-commerce order code.
`merchant.entity`	✅	Used to route the request in Access Worldpay, created as part of on-boarding.
`paymentInstrument.type`	❌	An identifier for the `paymentInstrument` being used. `type` : `card/front` See JWT + BIN (card) above `type` : `card/tokenized` See JWT + BIN (token) above

paymentInstrument.type

❌

An identifier for the paymentInstrument being used.

type : card/front

See JWT + BIN (card) above

type : card/tokenized

See JWT + BIN (token) above

        }]
    }
}

Parameter	Description
`deviceDataCollection.jwt`	A digitally signed token that contains additional details required for DDC. Expires in 10 minutes for both Try and Production.
`deviceDataCollection.url`	A `POST` action on the DDC form. Used to redirect to the issuers DDC page.
`deviceDataCollection.bin`	First six digits of the card number (Bank Identification Number), used as part of DDC. Returned if a token resource or card number is included in the request.

Note

In case of an error, you can get further information in our error reference.

Device Data Collection (DDC)

Once you have the JWT and BIN you can create and submit the DDC form.

Create an iframe with an automatic form post in order for the issuer to collect the customer's browser device data (fingerprint). A SessionId representing this collection is then used as part of the risk analysis by the issuer in the authentication request.

Device Data Collection form

Here's an example of how you would set-up the DDC form in an iframe.

<iframe height="1" width="1" style="display: none;">

    <!-- Set the action to the value in the 'deviceDataCollection.url' from the device data initialization response --->
    <form id="collectionForm" name="devicedata" method="POST" action="https://ddcUrl.example.com">

      <input type="hidden" name="Bin" value="555555" />
      <!-- Use value from 'deviceDataCollection.bin' from the device data initialization response or add the card number -->

      <!-- Set to the value of 'deviceDataCollection.jwt' from the device data initialization response  --->
      <input type="hidden" name="JWT" value="eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJPcmdVbml0SWQiOiJPcmdVbml0IiwiaXNzIjoiYXBpSWQiLCJleHAiOjE1NjI5MjMzNDYsImlhdCI6MTU2MjkyMzQwNiwianRpIjoiYTAzMWVhOGEtN2E0Zi00YTQwLWI1NjMtOTUzMzYzMzVhZGNmIn0.0IK74OIXBxFsxqeOURJz1TFnz14ZTbFJTdTWo9cHUJQ" />

      <script>
      window.onload = function() {
        document.getElementById('collectionForm').submit();
      }
      </script>

    </form>
</iframe>

Device Data Collection postMessage

Once the DDC form is submitted and is successfully sent to the card issuer, you are notified via a postMessage event.

For security, verify the sender's identity using the postMessage origin property as detailed here.

Environment	Origin
Try	https://secure-test.worldpay.com/
Production	https://centinelapi.cardinalcommerce.com

An example postMessage response:

{
  "MessageType": "profile.completed",
  "SessionId": "0_3XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXX6b5",
  "Status": true
}

Key	Value
`messageType`	`profile.completed`
`SessionId`	UUID, not present or `undefined`
`Status`	`true` - Use the `SessionId` value in `deviceData.collectionReference` as part of the Authentication request false - SessionId is empty. Either retry DDC or send the authentication request without the `deviceData.collectionReference`. This downgrades the authentication to 3DS1.

Note

If no postMessage is provided either retry DDC or send the Authentication request without the deviceData.collectionReference. This downgrades the authentication to 3DS1.
