# CheckFinancialData

CheckFinancialData is the request payload for [FinancialDataApiClient](../SAIF.Data.Guidewire.Clients/FinancialDataApiClient.md).CreateCheckAsync, describing a check financial transaction — claim identification, approver, delivery and issue details, service date range, print/EOB flag, and the list of [Payment](Payment.md) line items to post. All properties carry explicit `JsonProperty` attributes mapping to Guidewire's camelCase JSON field names.

## Purpose
- Carries all fields required to create a check financial transaction against a Guidewire claim, including its constituent payment line items

## Context
- Namespace: `SAIF.Data.Guidewire.Models.FinancialDataApi`
- Assembly/package: `SAIF.Data.Guidewire` (packaged in `SAIF.SAIFCode.Core`)

## Behavioral notes
- A non-success HTTP response when posting this payload via `CreateCheckAsync` throws with the status code and response content*.
- `PayeeToAddressOverride` is only included in the serialized request when set (`NullValueHandling.Ignore`).
