Using the Sandbox

When you sign up for a US ShipEngine account, you will automatically be provided a Sandbox environment for testing purposes. In the Sandbox, you can freely create labels, get rates, and test ShipEngine’s various available resources.

Check out our developer documentation for additional information regarding the ShipEngine Sandbox!

US Accounts Only

At this time, the Sandbox is only available for US accounts. ShipEngine is looking to add Sandbox environments for non-US accounts in the future.

To access your Sandbox environment:

  1. Sign in to your ShipEngine Dashboard.

  2. Click the Environment drop-down and select Sandbox.

    The ShipEngine Sandbox Dashboard is displayed.

In the Home section of the Sandbox dashboard, you can manage your Sandbox API Keys. All Sandbox API Keys will begin with TEST and only work with the ShipEngine Sandbox carriers.

You also have access to test carrier accounts for (USPS services), UPS, and FedEx. Go to Connections and then Carriers to view your Sandbox carrier accounts. Each carrier will have a unique Carrier ID that you can use in your test API calls.


Sandbox accounts will not necessarily have the same rates that you see in your carrier accounts. As these are test accounts, the rates do not reflect what you will see when you move to the Production environment and begin using your actual connected carriers.

Ready to switch to Production?

Click the Activate Production Environment button from anywhere in the dashboard to go live in your Production environment. See our Getting Started FAQ for more details.
