# Authentication

All API requests require a Bearer token in the `Authorization` header. Your API key is available in the dashboard under Settings.

```bash theme={null}
Authorization: Bearer YOUR_API_KEY
```

Keys are scoped to your role: banks, merchants, and providers each receive separate keys. Use sandbox keys for development and live keys for production.

```bash theme={null}
curl -X GET "https://api.peere.network/v1/merchant" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json"
```

API keys are shown once on creation. Store them securely and never expose them in client-side code. To rotate a key, generate a new one in the dashboard, update your applications, then revoke the old key.
