Authorization with PSD2 Exemption

The following part is relevant only for PSD2 solution
In order to pass the bank a request for exemption from 3DS following Forter's recommendation in the Order Response, you should adjust your integration with the PSP and include in the PSP Authorization request a flag for TRA Exemption or Low Value or Secure Corp Exemption.

Contact your PSP to enable such a call (it is not always activated by default), and get their relevant Authorization API reference which explains how to pass a request for TRA Exemption and Low Value Exemption.

Examples for common PSPs

Navigate to Risk > Risk Settings > General > Perform TRA. Choose Enable 3rd party/proprietary risk solution TRA to apply the TRA exemption yourself per transaction.

3. Pass the relevant exemption type (transactionRiskAnalysis\ lowValue\ secureCorporate) in the scaExemption object, following Forter's recommendation (REQUEST_SCA_EXEMPTION_TRA \ REQUEST_SCA_EXEMPTION_LOW_VALUE \ REQUEST_SCA_EXEMPTION_CORP) . Example:

{"additionalData":{"scaExemption":"lowValue"}}
