3DS features

If your account supports 3D-Secure and credit card supports 3D-Secure, then Payment Platform will return the link to the 3D-Secure Access Control Server to perform 3D-Secure verification. In this case, you need to redirect the cardholder at this link. If there are also some parameters except the link in the result, you will need to redirect the cardholder at this link together with the parameters using the method of data transmitting indicated in the same result.

In the case of 3D-Secure after verification on the side of the 3D-Secure server, the owner of a credit card will come back to your site using the link you specify in the sale request.

⚠️ NOTE:

As per our API for any 3DS transaction after request, we send to merchant response with:

• redirect_url - URL to which the Merchant should redirect the Customer
• redirect_params - Object of specific 3DS parameters. It is an array if redirect_params have no data. The availability of the redirect_params depends on the data transmitted by the acquirer. Redirect_params may be missing. It usually happens when redirect_method = GET (or others).
• redirect_method - The method of transferring parameters (POST or GET) Redirect_params is a value that depends on any particular acquirer. Possible redirect_params: PaReq, TermUrl, and many other multiple values. Each acquirer can send values in different ways and our interface is unified to be able to process redirects to all versions of 3DS and redirection regardless of the acquirer.

Our API states that the merchant has to take mentioned parameters as is and redirect users with them, no need to parse them, split them, or divide them.

e.g. in this case, you would simply POST that string AS IS to the redirect_url:
