# Authentication

API Keys are used to authenticate with the API. All requests to the Rep.ai API must be authenticated by including an HTTP header with your API Key. 

* API Keys are tied specifically to your Organization.
* Multiple API Keys can be created for different uses.
* API Keys can be deactivated when no longer needed.
* API Keys are irretrievable, so when one is issued, please keep it safe!

## Get an API Key

To request an API Key, send an email to <sales@rep.ai> specifying the Organization you're requesting an API Key for.&#x20;

## Using your API Key

All requests must include the `X-Api-Key` HTTP Header, set to the value of your API Key.

&#x20;

{% code title="Example API KEY Usage" %}

```bash
# List all users of my Organization

-H "Accept: application/json" \
-H "X-Api-Key: BGFEUUEr.YmGIxL9maFhPtapAQW9RK5RX1MX3SjLRKaJJJ_96yVg"
```

{% endcode %}
