Description

How it works

This workflow captures idea submissions from a webhook and enriches them using AI.
It extracts key fields like Title, Tags, Submitted By, and Created date in IST format.
The cleaned data is stored in a Notion database for centralized tracking.
Finally, a confirmation message is posted in Slack to notify the team.
