About S2S Blacklist Editing in Paygate

General information about Server-2-Server blacklist editing

Scope: Right now, editing a blacklist can only be done via Analytics or via Merchant Services, this process is unfortunately slow and time consuming. Merchants needing to edit a huge number of transactions, or needing immediate control, including confirmation of the update done, requested this new Paygate feature. Computop will now be offering the possibility to edit a Blacklist via server-to-server.

Integration: A merchant should send a request to blacklist.aspx with usual parameters like MerchantID, Data and Length. In encrypted data, there must be a parameter EventToken for Insert, Update or Delete and a parameter BlackListInfo with all the information about the blacklist item. The value of BlackListInfo is a JSON-String. The Paygate first checks, if the merchant has the right to send such a request. Depending on the request result, it creates a BlackListInfo object and can perform the action insert, update or delete in the blacklist database. The next step is a response from the Paygate to the merchant. There will be a parameter Status, which can have the value OK or FAILED. In case of OK there will also be a parameter BlackListInfo which delivers all blacklist information as JSON-String. In case of FAILED there will be a parameter Description, which gives an indication why the request failed.

In order to block a card on several MerchantIDs at the same time, but without having to send a request for each MerchantID, it is possible to define a Master-MerchantID and various Sub-MerchantIDs. Then it is sufficient to send a request to the Master-MerchantID with the necessary data and the block will then also apply to all Sub-MerchantIDs at the same time.

If you are interested in this special function, please contact our Merchant Support so that the necessary configuration can be discussed and established.

(info) you also can add a German Bankleitzahl (BLZ) to blacklist by a record like this: DE00xxxxxxxx0000000000 where xxxxxxxx is the BLZ you want to blacklist. While EDD processing DE-IBAN is separated into BLZ/Konto so this BLZ will be blacklisted even if IBAN is used.

(info) Sie können auch eine Deutsche Bankleitzahl (BLZ) auf Blacklist setzen, indem Sie eine IBAN verwenden wie: DE00xxxxxxxx0000000000 wobei xxxxxxxx die BLZ ist, welche Sie auf Blacklist setzen möchten. Während des EDD-Prozessings wird die DE-IBAN in BLZ/Kontonummer aufgesplittet, so dass diese BLZ auch bei Eingabe der IBAN gesperrt wird.
