# Fehlerbehandlung

Es gibt viele Situationen, in denen Sie einem Client, der Ihre API benutzt, einen Fehler zurückgeben müssen.

Dieser Client könnte ein Browser mit einem Frontend, Code von jemand anderem, ein <abbr title="Internet of Things – Internet der Dinge: Geräte, die über das Internet Informationen austauschen">IoT</abbr>-Gerät, usw., sein.

Sie müssten beispielsweise einem Client sagen:

labels.design_file_name=File Name (optional)
labels.design_button_upload=Upload
labels.design_file_title_edit=View Page File
labels.design_edit_button=Edit
labels.design_download_button=Download
labels.design_delete_button=Delete
labels.design_use_default_button=Use Default
labels.design_title_edit_content=View Edit Page File
labels.design_button_update=Update
labels.design_button_back=Back

          }
        };
  }
