{% endhint %}

### Key Types <a href="#key-types" id="key-types"></a>

#### Secret API Key <a href="#secret-api-key" id="secret-api-key"></a>

A secret API key is for use on the server side and is not to be shared with the front end.

Example Key: `sec_23hcfb8374bfhc833i4uhx`

#### Public API Key <a href="#public-api-key" id="public-api-key"></a>

A public API key is for use on your website to call the API. These keys are limited to your domain and are safe to share publicly.

Example Key: `pub_3ficuhb34u8fnxu34h9fm`

### Authenticating Requests <a href="#authenticating-requests" id="authenticating-requests"></a>

When making requests to the APIs, include the key in your request.

```
Authorization: ApiKey {your API key}
```

### Other Authentication Methods <a href="#authenticating-requests" id="authenticating-requests"></a>

We also support [OAuth](/authentication/oauth-authentication.md), you can read more about this authentication mechanism here.
