Environments
Sandbox
Topper's sandbox is an environment that simulates the live Topper production environment. The sandbox environment provides a space where you can test your integration with Topper without touching any live accounts, and without using any real funds.

If you face issues initializing Topper and see a 'something went wrong' error page, check the devtools console for details on the bootstrap token validation.
