#### Issue: Authentication errors on API calls

**Solution**:
- Verify credentials: default is `admin`/`admin`
- Check if API is enabled in `system.properties`
- Use proper authentication header:
  ```bash
  curl -u admin:admin ...
  # or
  curl -H "Authorization: Basic YWRtaW46YWRtaW4=" ...
  ```

#### Issue: Large bulk imports timing out

**Solution**:

`Response` parametresini dependency'lerde de tanımlayıp, onların içinde header (ve cookie) ayarlayabilirsiniz.

## Doğrudan bir `Response` döndürün { #return-a-response-directly }

Doğrudan bir `Response` döndürdüğünüzde de header ekleyebilirsiniz.
