This plugin sends the content you pass to it, plus any metadata you set (source, external_id, callback_url), to your configured LoopQuest deployment over HTTPS so a human can review it. Your API key is stored by Dify as a secret credential and sent only to LoopQuest as a Bearer token. The plugin stores no data itself.
