Three-Domain Secure or “3DS” is a messaging protocol merchants use to authenticate their customers’ card information when processing card-not-present (CNP) e-commerce or mobile purchases and payments. By enhancing authentication, 3DS helps prevent fraud and provides an additional layer of security for CNP credit card and debit card transactions. This service is provided by all four major card networks.
When using TabaPay's Account API to create or update a TabaPay account, TabaPay allows you to check if a card is already associated with another account. This is called duplicate card check. If we detect that you are trying to create a duplicate account (same card), then we return a 409 response and give you the account_id associated with said card.
