# Authentication

When you complete your register in TurinPay Web App, you will receive a pair of api keys.

With _**Development Key**_, you can operate in the sandbox environment (testnet), and with _**Production Key** api key you can operate in the production environment (mainnet)_

You can find your API Keys in the **API Keys** menu option.

Authentication to the API is performed via HTTP, using the **apiKey** header.

```json
{
  "apiKey": "turinpay_sk_test_eee78-de9e-4e84-b2e6-fc2ae0687"
}
```

{% hint style="danger" %}
It's mandatory to pass successfully a **KYB** process in TurinPay for using apiKey in production environment (mainnet)&#x20;
{% endhint %}
