</Note>

## Authentication

The Hamsa API uses **API Key token authentication**. Include your API key in the `Authorization` header of every request:

```
Authorization: Token <API Key>
```

You can create an API key from the dashboard. See [Create API Keys](/overview/create-api-keys) for details.

## Project ID

Some endpoints require a **Project ID** to identify which project the request applies to. See [Finding Your Project ID](/overview/projects/overview#finding-your-project-id) for how to retrieve it.
