Real-Time UTM Check on Submitted Campaign Links via Webhook

This workflow exposes a webhook endpoint that any internal form, browser extension, or shortlink generator can call with a candidate campaign URL. It validates the UTM parameters synchronously and returns an approval verdict in the response, so the submitting tool can block a bad link at the point of creation. Every rejection is appended to an Airtable audit log for trend analysis.

Use it when you want UTM compliance enforced at the exact moment a link is minted — inside your link-shortener, a Notion form, or a custom marketing portal — rather than catching errors later in a sheet.

1. 1An HTTP webhook receives a POST with the candidate URL and submitter metadata.
2. 2A logic step parses the URL and validates every UTM parameter against the convention and required-field rules.
3. 3It branches on the result: approved links return a 200 with a clean verdict; rejected links return the specific failure reasons.
4. 4For any rejection, the workflow appends a row to the Airtable audit log capturing the bad link, reason, and submitter.
5. 5The verdict payload is returned to the calling tool as the webhook response.
