# Authentication

> Learn best practices for managing authentication, securing requests, and maintaining seamless API access for your integration.

<Note>All requests require an `Authentication` payload to be sent with the request.</Note>

All requests to the Health Street API must include an `Authorization` header with your API key.

## Example

```shell Shell theme={null}
curl https://api.glass.fm/v2/action/person \
     --header "Authorization: Bearer $HEALTHSTREET_API_KEY"
```
