Zapier Webhook Integration Not Triggering
You connected your Base44 app to Zapier using webhooks to automate workflows (new record creates a Slack message, form submission adds to Google Sheets, order triggers Mailchimp email) but the Zapier zap never fires. New records are created in Base44 but nothing happens on the Zapier side.
Webhook integrations are the primary way Base44 apps connect to external services. When they fail, all your automated workflows break: CRM syncing stops, notification pipelines go silent, and the integrations your business depends on quietly stop working.
The failure is often silent. Base44 doesn't report that the webhook call failed, and Zapier shows no incoming data. You only discover it when you notice that downstream actions haven't been happening.
Error Messages You Might See
Zapier: Waiting for trigger data
Webhook delivery failed: 404 Not Found
No data received by Zapier webhook
HTTPS connection to hooks.zapier.com failed
Payload rejected: invalid JSON format
Common Causes
- Wrong webhook URL — The Zapier webhook URL was copied incorrectly or changed when the zap was re-created
- Webhook trigger not configured — Base44 has a webhook URL saved but no trigger event configured to fire it
- Payload format mismatch — Zapier expects JSON but Base44 sends form-encoded data, or vice versa
- Webhook URL expired — Zapier webhook URLs can change when a zap is modified, but the old URL is still configured in Base44
- HTTPS certificate issue — The webhook call fails silently due to SSL/TLS certificate validation errors
How to Fix It
- Verify the webhook URL — Copy a fresh webhook URL from Zapier and update it in your Base44 configuration
- Test with a manual webhook call — Use a tool like webhook.site or Postman to send a test payload to the Zapier URL and confirm it receives data
- Check the trigger configuration — Ensure the webhook is configured to fire on the correct event (record created, updated, or deleted)
- Verify the payload format — Send a test request and check in Zapier's webhook history that the data format and fields match what downstream steps expect
- Monitor webhook delivery — If Base44 has webhook logs, check for failed delivery attempts and their error codes

Get HelpFrequently Asked Questions
How do I test if my Base44 webhook is actually sending data?
Use webhook.site to create a temporary URL and configure it in Base44 as the webhook endpoint. Trigger the event and check webhook.site for incoming requests. This confirms whether Base44 is sending the webhook at all.
Why did my Zapier integration suddenly stop working?
Zapier webhook URLs can change when you edit or recreate a zap. Check if the URL in Base44 still matches the current zap's webhook URL. Also verify that the zap is turned on and hasn't been paused due to errors.
