# Using the Try It feature

> Send live requests to the Lerian sandbox directly from the documentation, with real responses and a controlled environment.

The **Try It** feature lets you interact with our APIs directly from the documentation. It gives you an embedded playground where you can test real requests and responses in a safe and controlled environment.

Every request sent through Try It runs against our sandbox. If you want to understand how the sandbox works under the hood, check the page [Using our Sandbox](/en/reference/using-our-sandbox).

## What you can do

***

With **Try It**, you can:

* Send live requests to our sandbox environment
* Inspect full HTTP request and response details
* Adjust headers, parameters, and body payloads
* Test different authentication tokens or organization IDs
* Explore error handling and validation scenarios with mock data

## Before you start

***

You will need the required headers for each API. Examples include `Authorization`, `X-Lerian-Id`, or `X-Organization-Id`. Each endpoint specifies exactly which headers you must use.

<Danger>
  The sandbox resets automatically every day.

  Any entity you create, such as Organizations, Ledgers, or Portfolios, will be deleted within 24 hours.

  When testing dependent endpoints, create the required entities again before sending new requests.

  For example, you must create an Organization before creating a Ledger. Use the returned `organization_id` in the path.
</Danger>

## How to use it

***

<Warning>
  The **Try It** feature is available only in the **latest version** of our documentation.

  If the Try It button is missing, switch to the newest version using the selector at the top of the page.
</Warning>

<Steps>
  <Step>
    Open any endpoint in the **API Reference**.
  </Step>

  <Step>
    Click the **Try It** button next to the endpoint path.
  </Step>

  <Step>
    Fill in the input fields such as query parameters, body content, or headers.
  </Step>

  <Step>
    Click **Send Request** to run the call.
  </Step>

  <Step>
    Review the response body, status code, and headers shown below the request.
  </Step>
</Steps>

<Tip>
  You can copy your request as `curl` or `fetch` using the code tabs. It is a simple way to move from testing in the docs to running calls in your local environment.
