# Page: Response Payloads

## Purpose

This page explains how response payloads are interpreted in the fraud and AML workflow and how they support decision-making.

## What a response payload is

A response payload is the structured output returned by a rule, model, or service after processing a transaction or event. It provides the operational details behind the decision.

## What users should look for

Common elements in a payload may include:

- status or decision outcome;
- score or risk value;
- reasons or explanation fields;
- identifiers linked to the original request;
- rule or model references.

## Example usage

Example: after a transaction is evaluated, the response payload shows why it was approved, declined, or flagged for review. The investigator uses this information to understand the system’s decision.

## Practical guidance

- read the payload to understand the reason behind a decision;
- use the payload to verify whether the expected rule or model was applied;
- treat the payload as evidence when explaining outcomes to downstream teams.

## Notes

Response payloads are a bridge between the rules engine and the human reviewer. They make automated decisions easier to understand and audit.
