# Authentication

# API key

To access ClickGUARD API you will need an **API key**. You can obtain your API key by visiting [this page](https://app.clickguard.com/user/api) in the ClickGUARD dashboard.

Your API key will look something like this: `T2hhjZhRnNlKmZkZGMxYzN5U2NilDO0kTMlhlZyYTN`.

# X-API-KEY header

When making HTTP requests, you need to put your API key in the `X-API-KEY` header.

Requests without `X-API-KEY` headers will return HTTP `401 Unauthorized` error.
