ParameterMandatoryDescription
transactionReferenceA unique reference for authentication. for example, e-commerce order code.
merchant.entityUsed to route the authentication request in Access Worldpay, created as part of on-boarding.
instructionThe object that contains all the payment information related to the authentication request.
instruction.paymentInstrumentAn object that contains the card details or token location.
paymentInstrument.typeAn identifier for the paymentInstrument being used.

type : card/fronttype : card/tokenized
paymentInstrument.billingAddressAn object containing the billing address information. If included you must send at least:
  • State - should only be provided following the ISO-3611-2 two-character sub division e.g.“CA” for California). We recommend you provide this for US addresses
deviceData.acceptHeaderUsed by the issuer to check if the customer's browser is compatible with the issuer challenge display.
deviceData.userAgentHeaderUsed by issuers as part of risk analysis and correctly displaying the challenge. Must conform toRFC 7321
E.g. Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:47.0)
deviceData.collectionReference.

Note: If no value is provided the authentication falls back to 3DS1.

deviceData.browserLanguageYour customer's browser language that can be used by the issuer in risk analysis. Must conform to the language tags defined by IETF. E.g. en-GB, fr-FR
deviceData.ipAddressA unique identifier for your customer's physical location that can be used by the issuer in risk analysis. Must be in IPv4 format. E.g. 192.0.0.0
challenge.windowSizeSpecify the challenge window size (width x height) that the issuer should use. This is to better tailor the experience to the customers device.
  • 250x400
  • 390x400 (default)
  • 600x400
  • 500x600
  • fullpage - expand to fill viewport

Note: The 3DS1 specification default is 390x400 but we recommend a minimum of 400x500 as not all issuers conform strictly

challenge.preference
  • noPreference - default
  • noChallengeRequested - prefer no challenge performed
  • challengeRequested - prefer challenge is performed
  • challengeMandated - local or region mandates meaning a challenge must be performed

Note: The interpretation of this field varies from issuer to issuer, so Worldpay cannot guarantee any particular behaviour on their part as a result of you setting this field.

challenge.returnUrlOnce the customer completes thechallengepage the issuer will redirect/post to the returnUrl in order for you to resume the session. It must be the full URL path.

Note: The issuer prioritizes device data collection values for risk analysis over the browser language and IP address details. We recommend you still include these details. In case of unsuccessful device data collection, the authentication may fail if you do not include them.

Optional fields in an Authentication request

Risk data

To reduce the chance of a challenged outcome we recommend that you include additional riskData in yourauthentication request.

The additional riskData is used by your customer's card issuer. It decides if your authentication request requires a challenge or can be authenticated successfully without a challenge (also known as frictionless authentication).

Note: Recommended values for a frictionless authentication are marked in the tables below and may become mandatory in future versions of the API.

There are three riskData objects you can include in your request:

Authentication responses

The response contains the outcome of your authentication request.
