# Authentication

> Learn how to authenticate with Clinia's API using API keys.

The Clinia API uses an API Key to authenticate requests.

<Note>
  If you don't already have an API key, reach out to Clinia's support team at [support@clinia.com](mailto:support@clinia.com).
  API Keys can also be generated through the system. See [Users and Service Accounts](/iam/users) for more details.
</Note>

Your API keys carry many privileges, so be sure to keep them secure. Don't share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.

Authentication to the API is performed with HTTP Headers. Provide your API key in the headers with an `X-Clinia-API-Key` key.

<Note>
  You must make all API calls over HTTPS. Calls that you make over plain HTTP will fail. API requests without authentication will also fail.
