# `Worldpay.Exemptions`
[🔗](https://github.com/iamkanishka/worldpay/blob/v1.0.0/lib/worldpay/access/exemptions.ex#L1)

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)

# `request`

```elixir
@spec request(map(), Worldpay.Config.t()) ::
  {:ok, map()} | {:error, Worldpay.Error.t()}
```
