# Trial

> Learn how to use the Zamp API trial environment to explore and test before going live.

The Zamp platform provides a free API trial environment for developers to explore and test APIs before going live.

<Note>
  Trial data is rate-limited and automatically deleted after 30 days. When your API token is generated, Zamp automatically configures the test environment to include all 47 remote seller state registrations.
</Note>

You must agree to the [Developer trial terms and conditions](/guides/developer-trial-terms-and-conditions) before proceeding.

## Step 1: Get a Registration Code

To begin, you need a registration code to generate an API token.

The single-use registration code will be sent to your business email address and will expire 30 minutes after it is generated.

1. Enter your business email address
2. Receive a single-use registration code via email
3. Use the code before it expires (30 minutes)

<Warning>
  Always keep your token safe and reset it if you suspect it has been compromised.
</Warning>

## Step 2: Generate an API Token

Using the registration code received in Step 1, generate your API token.

* Enter the registration code from your email
* Your token expires after 30 days
* All test environment data automatically deletes after 30 days

## Step 3: Authenticate and Begin Testing

Once your API token is generated, you can use it to authenticate requests and begin exploring the Zamp API.
