3DSv2 MMS Preferences

  • Home
  • 3DSv2 MMS Preferences

3DSv2 settings are found under the 3DS Checks and PDS2 tabs of the Preferences section in the MMS. In addition to the previous 3DSv1 settings available, Merchants can now choose their 3DS policy, 3Ds version and which exemptions they would like the Gateway to automatically apply here.

3DS Checks Tab

Merchants can choose how and when 3DS is used in their transaction flow under the 3DS Checks Preferences tab:

3D Secure Policy

Merchants need to choose how and when to request exemptions to Issuers. They can opt to Authenticate before or after Authentication.

Authentication Before Authorisation – Transactions submitted using 3D Secure for authentication with an exemption indicator applied. The authorisation will then be submitted with the appropriate authentication data including the exemption indicator.

The authorisation may be eligible for the 3D Secure liability shift.

Authentication After Authorisation, when requested by the Issuer – This bypasses initial 3D Secure authentication and submits transactions directly to authentication with an exemption indicator.

If the Issuer accepts the exemption no further additional authentication is required, however the issuer has the right to request that authentication be performed and the transaction be resubmitted for authorisation with the additional authentication data.

The post authorisation authentication and authentication submission can be automatically performed by the Gateway or the Gateway can be set to decline the transaction and indicate it can be resubmitted if required (if the declined transaction is resubmitted you should request that authentication is performed before authorisation and not request an exemption again).

The initial authorisation will not be eligible 3D Secure liability shift.

Select one of the options from the dropdown to choose which policy to apply:

1. Before Authorisation or When Issuer Requests (Default)

2. Before Authorisation Only

3. When Issuer Requests Only (Bypass)

4. Before Authorisation or When Issuer Requests (PSD2)

5. Before Authorisation Only (PSD2)

6. When Issuer Requests Only (PSD2) (Bypass)


The PSD2 options will perform the 3D Secure authentication only if the transaction falls within the jurisdiction of the European Unions Payment Services Directive 2, otherwise it will behave as if 3D Secure had not been required.

3D Secure Version

Merchants can also choose whether to use the highest version of 3DS. We recommend that you use the highest version supported for the payment, however you can choose to only use the original 3D Secure version 1 if you are experiencing problems with a higher version.
