# Beacon API

### Beacon API

The Beacon API is the same API used by the CrowdPower JavaScript tag to identify customers and record events, and page views. This means your project’s public key can be used to access these endpoints — as well as a secret or application key. You can find your keys in [Settings](https://app.crowdpower.io/settings).

To authorize, send in your key as an Authorization header:

```javascript
Authorization: "Bearer <project_secret_key>"
```

You may also pass the key in as a request parameter:

```javascript
api_key: "<project_secret_key>"
```
