Website Form Submission Not Triggering Zapier Automation Properly

I connected my website contact form to Zapier using a webhook trigger, but the automation is not working consistently. Some form submissions successfully trigger the Zap, while others never appear in Zapier at all. The issue happens randomly, which makes it difficult to identify whether the problem is coming from my website, the webhook request, or Zapier itself.

I already verified that the webhook URL is correct, HTTPS is enabled, and the form submits successfully on the frontend. I also tested reconnecting the webhook and sending manual test data, which sometimes works normally. However, real user submissions occasionally fail to trigger the automation, even though the form appears to submit correctly on the website.

Has anyone experienced inconsistent webhook or form trigger behavior like this before? I would appreciate advice on how to properly debug webhook delivery, monitor failed requests, or improve the reliability of website-to-Zapier integrations. Any troubleshooting tips or recommended best practices would help a lot.

Hi ​@glenphillips32 

Which app is being used to trigger the Zap webhook URL?

Hi ​@glenphillips32 

could you share a screenshot and a quick description of what your Zap is doing? That would help us troubleshoot the issue better.

Hi glenphillips32,

The fastest way to narrow this down is to separate "form submitted" from "webhook delivered." I would check one real submission end to end and capture four points:

1. browser/form success event timestamp,
2. website server or form plugin delivery log for the POST,
3. Zapier Catch Hook raw request history,
4. Zap run history for the same timestamp.

If the form log shows a POST but Zapier has no hook request, the break is usually retry/timeout, conditional form routing, or a plugin integration that treats some submissions differently. If Zapier receives it but no Zap runs, then it is more likely a Zap trigger/filter/sample-data issue.

For a first pass, you do not need to share credentials. A redacted request payload, one failed timestamp, one successful timestamp, and the form tool/plugin name are enough to write a short diagnosis and test checklist.
