# Verify Redirect Response

## Overview

The `verify_redirect_response` method validates payment responses from redirect-based flows (3DS, bank redirects, wallet callbacks).

**Business Use Case:** When a customer returns from a 3DS challenge, verify the response is legitimate before fulfilling the order.

## Purpose

| Scenario         | Benefit                        |
| ---------------- | ------------------------------ |
| 3DS completion   | Validate authentication result |
| Bank redirect    | Confirm payment success        |
| Fraud prevention | Prevent spoofed notifications  |

## Request Fields

| Field                          | Type | Required | Description                 |
| ------------------------------ | ---- | -------- | --------------------------- |
| `merchant_order_id`            | str  | Yes      | Your unique order reference |
| `request_details`              | dict | Yes      | Redirect request details    |
| `request_details.headers`      | dict | Yes      | HTTP headers                |
| `request_details.query_params` | dict | Yes      | URL query parameters        |

## Response Fields

| `source_verified`          | bool          | Whether response is authentic |
| `connector_transaction_id` | str           | Connector's transaction ID    |
| `status`                   | PaymentStatus | Current payment status        |
| `status_code`              | int           | HTTP status code              |

## Example

### SDK Setup

```python
from hyperswitch_prism import PaymentClient

payment_client = PaymentClient(
    connector='stripe',
    api_key='YOUR_API_KEY',
    environment='SANDBOX'
)
```

### Request

```python
request = {
    "merchant_order_id": "order_001",
    "request_details": {
        "headers": {"Content-Type": "application/x-www-form-urlencoded"},
        "query_params": {

        },
        "body": ""
    }
}

response = await payment_client.verify_redirect_response(request)
```

### Response

```python
{
    "merchant_order_id": "order_001",
    "source_verified": True,
    "connector_transaction_id": "pi_3Oxxx...",
    "status": "AUTHORIZED",
    "response_amount": {

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.hyperswitch.io/integrations/prism/python/payment-service/verify-redirect-response.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
