| `payment/method` | The payment method associated with the transaction. [View possible values on our developer portal.](/minfraud/api-documentation/requests/#schema--request--payment__method)                                                                                                                                   |
| `event/party`    | The party submitting the transaction. Either `agent` or `customer`. This input can help reduce false positive potential in cases where an agent is submitting transactions on behalf of customers.

`event/type` now supports the additional values below.

Passing the additional inputs above can help us improve our risk scoring
accuracy for you by increasing the context available to our machine learning
models and heuristics.

Our [client APIs](/minfraud/evaluate-a-transaction#links-to-maxmind-client-apis)
have been updated to support these inputs so you may need to refresh yours to
submit them in your minFraud requests if you are not interfacing directly with
our REST API.
