# Sandboxes

Manage test sandboxes

Manage Sandboxes for email testing. Capture and inspect emails without delivering them to real recipients. This is ideal for development, staging, and QA environments.

#### Get your Sandbox ID

To use the Sandbox API, you need a Sandbox ID. You can get it in one of the following ways.

**Option 1: From the sandbox URL**

1. Open your Sandbox in Mailtrap.
2. Copy the ID from the sandbox URL.

Example:

* URL: <https://mailtrap.io/sandboxes/2564102/settings>
* Sandbox ID: 2564102

**Option 2: Via the API**

Use the `Get a list of sandboxes` endpoint to retrieve all Sandboxes in your account.

## 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.mailtrap.io/developers/email-sandbox/sandboxes.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.
