SecurePlus

UnionPay requires an additional security layer, SecurePlus, which uses telephone verification.

To use SecurePlus in Classic integration:

  1. Make an /authorise call and include the telephoneNumber field.
  2. If a response contains paRequest set to CUPSecurePlus-CollectSMSVerificationCode, this indicates that a verification code was sent to the provided phone number. On your web page, collect this verification code from the shopper.
  3. Make an /authorise3d call including: 
    • paResponse – the verification code that you collected from the shopper.
    • browserInfo – the shopper's browser information.
    • In additionalData, include the  mpiImplementationType field and set its value to CUPSecurePlus to indicate that you are making a SecurePlus request.
  4. You get a response with the payment status.

To use SecurePlus in Hosted Payment Pages:

  1. Make an /authorise call including the shopper.telephoneNumber field.
  2. A verification code is sent to the phone number provided by the shopper.
  3. After the shopper enters the code, Adyen processes the payment and sends you a response.

This flow is a part of our Risk Management system, and the authentication may be triggered dynamically based on the risk thresholds set by you.
