The Sandbox environment is where your integration with the Tesouro API begins.

Use the Sandbox to validate your integrations and business scenarios before going live. We also recommend using it when transitioning to newer API versions — connect your staging environment to our Sandbox to test changes before deploying to Production.

* Sandbox data and settings are separate from Production and cannot be migrated.
