# Using our Sandbox

> An isolated environment that mirrors production behavior and powers the Try It experience inside the documentation.

The sandbox helps you explore Lerian’s APIs in a safe and predictable environment. It mirrors production behavior while keeping your real data untouched. Every request you send from our documentation is routed through this environment, giving you a complete view of how each endpoint behaves.

The **sandbox fully powers the Try It experience**. When you test an endpoint, the response you see comes from this environment. If you haven't seen how the Try It feature works yet, check out the [Using the Try It feature](/en/reference/using-try-it) page.

<Note>
  The sandbox is only available inside the documentation. You cannot access it directly through external tools.

## Base URLs

***

These are the URLs the documentation uses behind the scenes when you test an endpoint:

| Service        | Sandbox Base URL                                                                                                       |
| -------------- | ---------------------------------------------------------------------------------------------------------------------- |
| Midaz          | `https://onboarding.sandbox.lerian.net` (Onboarding APIs) `https://transaction.sandbox.lerian.net` (Transactions APIs) |
| Access Manager | `https://auth.sandbox.lerian.net` (Auth APIs) `https://identity.sandbox.lerian.net` (Identity APIs)                    |
| CRM            | `https://crm.sandbox.lerian.net`                                                                                       |
| Fees Engine    | `https://fees.sandbox.lerian.net`                                                                                      |
| Reporter       | `https://smart-templates.sandbox.lerian.net`                                                                           |

All examples and test boxes in the docs already use these URLs.

## What you can do

***

The sandbox lets you:

* Run live requests from the documentation
* Inspect request and response structures
* Understand authentication headers and data formats
* Learn how each API behaves without setting up your own environment

<Tip>
  Click **Try It** on any endpoint to run a live request and check how the API responds.
</Tip>

## Limitations

***

The sandbox is designed for exploration. Some restrictions are intentional:

* It only works inside the documentation
* Data resets frequently
* Some endpoints use fixed or sample responses
* Authentication rules may be simplified depending on the API

For full integration tests, use your own environment or reach out to our team to request a dedicated development space.
