  • SolidGate API - full host2host REST API. Parameters are transmitted with POST-method in the request body (JSON format). The payment form is hosted on the Merchant's end.



3-D Secure

3DS (3-D Secure) — known as Verified By Visa and MasterCard Secure Code. These are the programmes of respective Card Scheme so the issuer can check whether the cardholder does authorize the payment. It works as follows: cardholder specifies his/her card details, then issuer's website occurs where the cardholder is supposed to enter the secret code (usually mentioned in SMS). If the code is entered correctly, the payment will be approved. If not, it will be declined.

Operation of Sales can be performed via SolidGate with 3DS if 3DS-authentication required.
