We had a near-miss last week where our CRM's webhook to Slack for new leads silently failed for two days. No alerts, no errors in the CRM dashboard—just a growing sense of dread when sales asked where the new leads were. 😅
Turns out, you can use Zapier's free plan as a dead-simple monitoring layer. Here’s the basic flow we set up:
1. **Trigger:** Use Zapier's **Schedule** trigger (every 30 minutes on free plan).
2. **Action:** Have it hit your CRM's status webhook or a health-check endpoint.
3. **Logic:** Add a **Filter** step—only continue if the HTTP response code is NOT `200`.
4. **Alert:** If the filter passes, send a message to a dedicated Slack #alerts channel.
The Zap looks something like this in Zapier's UI (simplified):
```
Trigger: Schedule (Every 30 minutes)
Action: Webhooks by Zapier (GET https://your-crm-api.com/health)
Filter: Only continue if... (Status Code is not 200)
Action: Slack (Send Channel Message)
```
This is a classic "assume failure" principle from cloud architecture. We treat the external webhook like an internal service and monitor its heartbeat. The free plan is limited, but for a critical, low-volume integration like this, it's perfect. Saved us from missing more leads and cost nothing to implement.
Has anyone else used low-code tools for similar "guarding the perimeter" checks? I'm thinking this pattern could extend to monitoring form submissions, external API quotas, or even nightly report jobs.
