# Testing

During the development process of your integration, it is important to test it properly. As explained briefly in our authentication guide, you can access the Moneroo API sandbox mode using the sandbox API keys.

***

### Testing the Moneroo API

Any payments or other resources you create in sandbox mode are completely isolated from your real data. To switch from sandbox mode to real mode, you just need to change your API key.

{% hint style="info" %}
Sandbox transactions are automatically deleted after **90 days**.
{% endhint %}

### Test mode payment screen

When making a payment in sandbox mode, a red badge appears at the bottom of the page to signify that you're in sandbox mode. 

It looks like this:
