exposed on the checkout page, please check with your tokenization vendor regarding the availability of a detokenization proxy service such service enables you to make a request to a 3rd party (such as the forter api) with a placeholder for the full credit card value included in the request the request is then routed through the proxy, where the placeholder is replaced with the corresponding card data you can also check out our forter's https //docs forter com/card vaulting solution for a more seamless integration visa required data points starting from aug 2024 visa requires the following fields in order to execute 3ds browser ip address cardholder name cardholder email address or cardholder phone number (at least one of work, home, or mobile) if you collect those fields only for a subset of the transactions that's okay, but the portion without those fields will not have 3ds executed acquirer data contact your psp acquiring bank to request the details in the table below without these accurate details, 3ds cannot be executed and will fail acquirer bin/mid pairings usually follow these patterns card scheme acquirer bin acquirer mid visa 6 8 digit numbers starting with 4 usually numeric (but not necessarily so) mastercard 6 8 digit numbers usually starting with 5 or 2 (rarely 6 , 7 or 8 ) usually shared with visa (but paired with a mastercard bin) american express 11

request your acquirer bank to enroll your mids to 3ds2 on mastercard, as it is not done automatically like with visa if your acquirer is eu based, that's probably already the case, but still best to verify forter, as an external mpi, can execute 3ds only if the mids are enrolled with the card scheme to the 3ds service psp supports external 3ds mpi ensure that your psp is configured to receive and process the results of the 3ds authentication when using an external mpi like forter get the relevant api reference from your psp to request authorization with 3ds results clarify which additional fields about 3ds results should be populated (e g cavv, eci, 3ds version, xid, transid) see https //docs forter com/psp authorization for more details psp supports psd2 exemption requests relevant only for psd2 solution verify with your psp that you can request an exemption from executing 3ds for low value and low risk transactions in the authorization call get the relevant api reference from your psp to request authorization with an exemption request
