# Authentication

### Authentication Method

All requests must be made over HTTPS and will be authenticated over standard [HTTP basic authentication](https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication).

### API Authentication Key

Authentication requires a `x-api-key`. When these values are requested in console/terminal, programming libraries, SDKs, or even here in our docs, use the following values for `x-api-key:`

| Key       | Value      |
| --------- | ---------- |
| x-api-key | {API\_KEY} |

{% hint style="warning" %}
The API key must be kept secret. They should not be in your client-side code or checked into your application's code.
{% endhint %}

### Example Requests

<pre data-title="Ping Request"><code>curl --request GET \
<strong>    -u x-api-key:API_KEY \
</strong>    --url {Sanbox_URL}/api/ping
</code></pre>

### Current API Key

{% code title="Current API Key Request" %}

```
curl --request GET \
  -u x-api-key:API_KEY \ 
  --url {Sanbox_URL}/api/api_keys/current
```

{% endcode %}
