# Authentication - SMB Sales Boost API

All API requests require a valid API key sent as a Bearer token in the `Authorization` header. Generate your API key from the Dashboard → API tab (available on all paid plans).

### Example Request

```
curl -H "Authorization: Bearer smbk_your_api_key_here" \
  https://smbsalesboost.com/api/v1/me
```

### API Key Format

All API keys are prefixed with `smbk_` for easy identification.

### Security Best Practice

Never expose your API key in client-side code, public repositories, or browser requests. Store it securely as an environment variable.
