It also skips non-English titles to avoid unnecessary translation.\n## How it works\n\u30fbRSS watches a channel for new items.\n\u30fbYouTube API fetches the full snippet (title/description).\n\u30fbText is combined into a single payload and sent to DeepL.\n\u30fbThe translated result + original metadata is merged and posted to Slack.\n\n## Requirements\n\u30fbYouTube OAuth (for reliable snippet retrieval)\n\u30fbDeepL API key (Free or Pro)\n\u30fbSlack OAuth\n\n## How to set up\n\u30fbDuplicate this template.\n\u30fbOpen the Config (Set) node and fill in YT_CHANNEL_ID, TARGET_LANG, SLACK_CHANNEL.\n\u30fbConnect credentials for YouTube, DeepL, and Slack (don\u2019t hardcode API keys in HTTP nodes).\n\u30fbClick Execute workflow and verify one sample post.\n\n## How to customize\n\u30fbChange TARGET_LANG to any language supported by DeepL.\n\u30fbAdd filters (exclude Shorts, skip videos under N characters).\n\u30fbSwitch to Slack Blocks for richer formatting or thread replies.\n\u30fbAdd a fallback translator or retry logic on HTTP errors.\n## Notes & limits\nDeepL Free/Pro have different endpoints/quotas and monthly character limits. YouTube and Slack also enforce rate limits. Keep credentials in n8n\u2019s credential store; do not commit keys into templates. Rotate keys if you accidentally exposed them."
