# Redirect Request
> Learn how to use Requestly Interceptor's Redirect Rule for testing, debugging, and development, with step-by-step guides and use cases.
***
The **Redirect Request Rule** in Requestly Interceptor allows you to seamlessly redirect HTTP requests to a different URL or resource. This is particularly useful for testing, debugging, or even for creating workarounds during development.
## Why Use the Redirect Rule?
1. **Redirect Production to Local Environment:** Map your production scripts or APIs to your local running code and test your local code directly on production sites without deployment.\

2. **Test API version changes**: If a new API version is available, you can test backward compatibility by setting up a redirect rule to point all URLs from the old version to the new one. This lets you test the upgrade without modifying your code.\

3. **Swap Javascript from production to staging/dev environment:** Test your dev implementation in tag manager scripts like Adobe DTM, Tealium Tag, and Google Tag Manager Containers before pushing them live on client websites.

## **How to Configure the Redirect Rule**
Navigate to the HTTP Rules tab in the web or desktop app. Click on `+ New Rule` and select `Redirect Rule` from the options.
Provide a **descriptive name** for the rule to keep your setup organised. Optionally, add a **brief description** explaining its purpose for easier identification later.
Define where the rule should be applied by specifying criteria such as **URL**, **Host**, or **Path**. You can choose from options like **Regex**, **Contains**, **Wildcard**, or **Equals**, or use Advance Filters for more precise conditions.
For more details on source conditions, [read this guide](/http-rules/advanced-usage/advance-targeting).
For this example, we are using the Requestly Interceptor Playground (a demo eCommerce Store) to demonstrate the `Redirect Request` rule. This gives you a near-live experience of how the rule works.
In this case, we are targeting API requests that fetch data for the page, specifically those with query parameters like `type.slug:bakery`.
* **Condition Type:** URL
* **Operator:** Contains
* **Value:** `https://rest.requestly-playground.com/api/products?searchJoin=and&with=type%3Bauthor&limit=30&language=en&search=type.slug:bakery%3Bstatus:publish`
Set the target URL to which requests should be redirected. You can use the following options:
To redirect requests from one API endpoint to another, set the following:
* **Source URL**: `https://rest.requestly-playground.com/api/products?searchJoin=and&with=type%3Bauthor&limit=30&language=en&search=type.slug:bakery%3Bstatus:publish`
* **Redirect Target**: `https://rest.requestly-playground.com/api/products?searchJoin=and&with=type%3Bauthor&limit=30&language=en&search=type.slug:gadget%3Bstatus:publish`
In this case, we are changing the query parameter `type.slug:bakery` in the **Source URL** to `type.slug:gadget` in the **Redirect Target**. This redirects requests for bakery products to a new endpoint for tech products.
You can also import this rule and apply it directly by using this shared list**.**
> The local file option is available only in the [desktop app](https://requestly.com/downloads).
To redirect an API request to a local file, choose **File from your device** as the redirect target. This will serve the response from your local file instead of the live server.
You can redirect API requests to a custom response hosted on **Requestly Interceptor’s File Server**.
Choose from an existing **JSON file** or upload a new one.
Once selected, the request will return the hosted response instead of hitting the live server.
Once you are satisfied with your configuration, click `Save` to store the rule. After saving, make sure to toggle the rule `ON` to activate it. This will apply the rule and ensure it works as expected.
To verify that the rule is working, click the `Test button`, enter a relevant URL, and then click `Test Rule`.
You can use the following URL to test the redirection: `https://www.requestly-playground.com/?rq-category=redirect`.
There are multiple ways to validate if a rule is applied or not, learn more about how to `validate rule execution` .
