Get device fingerprint

POST https://{domainname}/v1/{merchantId}/productgroups/{paymentProductGroupId}/deviceFingerprint

Product Groups

Through this API you can retrieve payment product groups. A payment product group has a collection of payment products that can be grouped together on a payment product selection page, and a set of fields to render on the payment product details page that allow to determine which payment product of the group the consumer wants to select. We currently support one payment product group, named cards, that has every credit card we support (and every debit card that behaves like a credit card). Its cardNumber field allows to determine the right payment product through a Get IIN details call.

Request

In case you use your own payment pages and you want to use device fingerprinting to assess the risk based on the device that the consumer is using you will need to include a piece of JavaScript in your page. Using this API you retrieve a transaction specific JavaScript snippet that you need to include in your payment page. The snippet returned in html already contains the deviceFingerprintTransactionId that is specific to one single transaction. It is possible to execute another JavaScript function after the execution of device fingerprint snippet by including the function using the collectorCallback in the request.

Property Type Required Details
collectorCallback string no read close

Description

You can supply a JavaScript function call that will be called after the device fingerprint data collecting using the provided JavaScript snippet is finished. This will then be added to the snippet that is returned in the property html.

Responses

Please find below an overview of the possible responses.

Response 200 - OKDeviceFingerprintResponse

Returns html containing a transaction specific code snippet for injecting into your own payment page. This snippet already contains the deviceFingerprintTransactionId which must be submitted again when you submit the payment request through CreatePayment.fraudFields.deviceFingerprintTransactionId. It is also possible to submit the deviceFingerprintTransactionId in the Risk Assessment calls.

Property Type Required Details
deviceFingerprintTransactionId string yes read close
close

Description

Contains the unique id which is used by the device fingerprint collector script. This must be used to set the property fraudFields.deviceFingerprintTransactionId in either in the CreatePayment.fraudFields.deviceFingerprintTransactionId, the CreateRiskAssessmentCards.fraudFields.deviceFingerprintTransactionId or the CreateRiskAssessmentBankaccounts.fraudFields.deviceFingerprintTransactionId.
html string yes read close
close

Description

Contains the ready-to-use device fingerprint collector script. You have to inject it into your page and call it when the consumer presses the final payment submit button. You should only call it once per payment request.
