# Authentication

The Harmonizely API uses API keys to authenticate requests. You can view your API key in the [Harmonizely Integrations](https://harmonizely.com/integrations).

API requests without authentication will fail.

Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.

Add your API key to the `X-API-KEY` header to get the access to the API endpoints.

{% hint style="info" %}
To test requests using your account, replace the **\<your\_api\_key>** API key with your actual API key.
{% endhint %}

```bash
curl -H "X-API-KEY: <your_api_key>" https://harmonizely.com/api/users/me/meeting-types
```
