Automate Twitter Mentions Alerts with n8n and Slack

What This Automation Does

This workflow runs every 10 minutes to check for new mentions of a company Twitter handle.
It finds the last 50 tweets mentioning the handle.
It then filters tweets made only since the last run to avoid repeats.
Next, it formats the tweet text and URL link for Slack.
Finally, it sends those alerts as messages to a Slack channel.
This way, the team gets fast notifications about new tweets without checking manually.
