Worldpay Exemptions API — standalone SCA exemption requests.

Exemption types:

• "TRA" — Transaction Risk Assessment
• "lowValue" — Low-value payment (under applicable threshold)
• "trustedBeneficiary" — Trusted beneficiary
• "authenticationOutage" — Issuer authentication outage

For SCA exemptions embedded inside a FraudSight assessment, use Worldpay.FraudSight.assess/2 with the "exemption" field.

Example

{:ok, result} = Worldpay.Exemptions.request(%{
  "transactionReference" => "order-123",
  "merchant" => %{"entity" => "default"},
  "instruction" => %{
    "value" => %{"amount" => 500, "currency" => "EUR"},
    "paymentInstrument" => %{"type" => "card/plain", ...}
  },
  "exemption" => %{"type" => "TRA"}
}, config)
