Summary:
A WordPress site began receiving error alerts from Stripe about failed webhook deliveries. Freshy identified that the issue stemmed not from WordPress or Stripe directly, but from an inactive Zapier flow with a “Catch Hook” trigger. This case study outlines how we diagnosed and fixed the issue.
Issue background
The client received Stripe alerts about webhook delivery failures. These errors coincided with attempts to send invoice data to a Zapier-generated webhook URL.
At first glance, this seemed like a broken integration between WordPress and Stripe. However, the error was actually tied to a disconnected automation tool: Zapier.
Diagnosis
Freshy traced the failing webhook URL and confirmed it was part of a Zapier automation (Zap) used for syncing Stripe payments to QuickBooks Online (QBO). Specifically:
- The Zap used a “Catch Hook” trigger to receive data from Stripe.
- Zapier disables the webhook URL when the Zap is turned off.
- Stripe’s webhook delivery logs showed consistent 404 errors starting from the day the Zap was deactivated.
Since the Zap wasn’t actively processing any transactions, the Stripe errors were non-critical — but still cluttered the dashboard and alerts.
Resolution steps
- Verified flow: Confirmed the Stripe webhook was tied to an inactive Zap in the client’s Zapier account.
- Communicated options:
- If the Zap was no longer in use, the webhook could be safely removed from Stripe.
- If it would be reused, the Zap simply needed to be re-enabled.
- Client confirmed reactivation: The client wanted to resume using the Stripe → QBO integration.
- Zap re-enabled: Freshy restored the Zap, resolving the webhook errors without changing the Stripe or WordPress configuration.
Final outcome
After reactivating the Zapier flow, Stripe webhook errors stopped, and invoice syncing resumed automatically. This fix required no changes to WordPress or Stripe, just a deeper understanding of how Zapier manages webhook URLs.
