What it does

This workflow reacts in real time instead of on a schedule. When your ad platform posts a webhook for a variant exceeding an hourly spend threshold, it immediately checks that variant's recent CTR trend in BigQuery. If the variant is both spending hard and fatiguing, it records the incident in an Airtable budget-guard log and escalates a pause recommendation to Slack so someone can act before the day's budget is wasted on a tired creative.

When to use it

Use this for high-budget campaigns where a fatigued variant can quietly burn thousands before the next daily report. It is the safety net that catches fast-moving spend, not slow trends.

How it works

  1. 1The ad platform sends a webhook when a variant's hourly spend spikes.
  2. 2A guard step validates the payload and pulls the variant id.
  3. 3BigQuery returns the variant's recent CTR trend.
  4. 4A decision step confirms whether the variant is fatigued while spending.
  5. 5The incident is logged to Airtable, and a pause recommendation is escalated to Slack.
