# About sandbox

> Safely test the Equals API with sandbox-specific requests.

The **sandbox** environment allows you to safely test requests without impacting any of your production data. You can simulate a credit to add mock funds to your budget and test payments, or mock various card transactions.

<Info>
  Learn more about using sandbox in our [dedicated guide](/pages/get-started/generate-credits).
