Please note that the the communication between client and Access Control Server (ACS) is implemented through iframes. Thus, responses arrive in an HTML subdocument and you may establish correspondent event listeners in your root document. Alternatively you could solely rely on asynchronous notifications delivered to your backend. In those cases you may have to consider methods such as long polling, SSE or websockets to update the client. |

In order to start a server-to-server 3-D Secure card payment sequence please post the following key-value-pairs to
direct.aspx. Multiexcerpt include SpaceWithExcerpt EN MultiExcerptName BaseURL PageWithExcerpt Wording
Call of interface: general parameters
Notice: For credit card payments with 3-D Secure, please note the different cases as explained separately in the chapter at the start of the handbook. If the credit card is registered for Verified or SecureCode or SafeKey, the next phase is divided into two steps of authentication and payment. However it always begins in the same way via the direct.aspx interface. The first response however is the receipt of Javascript code or other parameters in order to carry out a second call up of the direct3d.aspx interface. Only after that, do you receive the listed parameter as a response.
To carry out a credit card payment via a Server-to-Server connection, call the following URL:

Notice: In case of a merchant initiated recurring transaction the JSON objects (besides credentialOnFile and card), the URLNotify and TermURL are not mandatory parameters, because no 3-D Secure and no risk evaluation is done by the card issuing bank and the payment result is directly returned within the response.

The Card Range Data data element contains information that indicates the most recent EMV 3-D Secure version supported by the ACS that hosts that card range.

The versioningData
object will indicate the EMV 3-D Secure protocol versions (i.e. 2.1.0 or higher) that are supported by Access Control Server of the issuer.
If the corresponding protocol version fields are NULL it means that the BIN range of card issuer is not registered for 3-D Secure 2.0 and a fallback to 3-D Secure 1.0 is required for transactions that are within the scope of PSD2 SCA.
When parsing versioningData
please also refer to the subelement errorDetails

3-D Secure Method
The 3-D Secure Method allows for additional browser information to be gathered by an ACS prior to receipt of the authentication request message (AReq) to help facilitate the transaction risk assessment. Support of 3-D Secure Method is optional and at the discretion of the issuer.
The versioningData
object contains a value for threeDSMethodURL
. The merchant is supposed to invoke the 3-D Secure Method via a hidden HTML iframe in the cardholder browser and send a form with a field named threeDSMethodData
via HTTP POST to the ACS 3-D Secure Method URL.

Authentication
If 3-D Secure Method is supported by the issuer ACS and was invoked by the merchant
will automatically continue with the authentication request once the 3-D Secure Method has completed (i.e. 3-D Secure Method Notification). Multiexcerpt include SpaceWithExcerpt EN MultiExcerptName Platform-Name PageWithExcerpt Wording
The authentication result will be transferred via HTTP POST to the URLNotify
. It may indicate that the Cardholder has been authenticated, or that further cardholder interaction (i.e. challenge) is required to complete the authentication.
In case a cardholder challenge is deemed necessary
will transfer a JSON object within the body of HTTP browser response with the elements Multiexcerpt include SpaceWithExcerpt EN MultiExcerptName Platform-Name PageWithExcerpt Wording acsChallengeMandated
