"content": "## How it works\nThis workflow automates a professional-grade translation pipeline. It triggers via Webhook or Schedule, translates source content into multiple target languages using DeepL, and then passes the results to an AI Agent. The AI evaluates the translation for accuracy and cultural nuance. \n\nApproved content is automatically published as a draft to WordPress, while any translations falling below quality standards are flagged in Slack for manual review. Finally, all results are aggregated and logged into Google Sheets to build a translation memory.\n\n## Setup steps\n1. **Credentials:** Connect your DeepL, OpenAI, WordPress, Slack, and Google Sheets accounts.\n2. **Configuration:** In the 'Translation Configuration' node, define your source language and list of target languages (e.g., DE, FR, JA).\n3. **Google Sheets:** Create a spreadsheet with headers: contentId, title, sourceLanguage, targetLanguage, translatedText, and qualityScore.\n4. **Slack:** Select your notification channels in the 'Flag for Manual Review' and 'Send Completion Summary' nodes."
