n8n Instagram Hashtag Monitor + Telegram Alerts (RecentReborn)

Never miss a new Instagram hashtag post—get instant Telegram alerts via n8n

This n8n workflow, n8n Instagram Hashtag Monitor + Telegram Alerts (RecentReborn), checks Instagram hashtag results using the RecentReborn API, deduplicates new mentions across runs, and sends Telegram notifications the moment something new appears (plus alerts if the API fails or returns an unexpected response).

What this workflow does

• Runs on a schedule (every 15 minutes) or via a manual test trigger.
• Loads a comma-separated hashtag list and the target Telegram chat ID from the configuration step.
• Splits the hashtag list into individual searches and queries the RecentReborn API for each hashtag’s Instagram results.
• Monitors API reliability: sends a Telegram warning if a hashtag request fails.
• Validates response format: checks that each API response includes a results field, and alerts via Telegram if the response is unexpected.
• Deduplicates across runs: stores workflow data and keeps only brand-new posts by URL across all tracked hashtags.
• For each new mention, sends a Telegram message with the author and the post link. If you run a manual test and there are no new results, it sends a single confirmation summary.

Use cases

• Monitor competitor, brand, or campaign Instagram hashtags and receive immediate Telegram alerts.
• Track community engagement for a launch and react quickly when new posts appear.
• Ensure your monitoring pipeline stays healthy—get Telegram alerts when the RecentReborn API fails or returns unexpected data.

Technical details

• RecentReborn API access using an HTTP Header Auth credential (API key).
• Telegram integration for warnings, validation issues, and new-mention notifications.
• Nodes used: if, set, code, http request, telegram, plus a sticky note for workflow guidance.

Setup: add your RecentReborn API key as an HTTP Header Auth credential, configure your Telegram bot and chat ID, update the hashtag list and telegramChatId, then activate the 15-minute schedule or use the manual trigger.
