CF7 webhook zapier, error message

Hi there 👋

Thanks for the detailed explanation. From what you described, this behavior is usually not caused by the webhook itself.

I tested this here with everything fully updated (WordPress, Contact Form 7 and my plugin) and could not reproduce the issue. The webhook worked correctly and no error message appeared.

Since the error disappears when you disable the webhook, but the data is still sent correctly, this usually means something else in the submission process is returning a failure status but not necessarily the webhook itself.

• Do you have Mail (2) enabled in Contact Form 7?
• Did you checked SMTP Logs?
• Did you checked webhook? Maybe webhook.site ?

Let’s try debug mode?

Please temporarily enable WordPress debug mode so we can see what is happening behind the scenes.

In your wp-config.php, add or update:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

Then:

• Submit the form again
• Check the file: /wp-content/debug.log

See if any errors are recorded at the time of submission.

Conflict Test

Temporarily deactivate all plugins except Contact Form 7 and the my plugin, and switch to a default theme (like Twenty Twenty-Four).

Then test the form again.

If the error disappears, it means there is a conflict with another plugin or your theme.
