Acquirer Exemption
The Acquirer Exemption Rule processes transactions where the acquirer has already performed risk analysis or authentication and is requesting an exemption. This applies when the 3DS Requestor Challenge Indicator is set to 05 (TRA already performed) or 07 (SCA already performed). In these cases, the acquirer has accepted liability.
Apata enforces a hard limit of €500 for acquirer exemptions in accordance with PSD2. Transactions above €500 are passed to the next rule regardless of configuration.
Parameters
All Merchants Toggle
When enabled, the configured action applies to all merchants. When disabled, a list of specific merchant names must be provided and the action applies only to those merchants.
Action
| Value | Behaviour |
|---|---|
Allow | Honours the exemption. The transaction is approved frictionlessly. |
Deny | Denies the exemption. The transaction is passed to subsequent rules. |
Max Transactions Before Challenge
Sets a per-merchant, per-card limit on the number of acquirer exemptions before a challenge is triggered. Once the limit is reached, the cardholder is challenged and the counter resets.
