Form troubleshooting tips
This document provides troubleshooting tips for setting up a form. If you have questions that aren’t answered here, visit our Support Forums to get more advice about how to debug your form.
# Custom success page
If you’re having trouble using the form
action to customize the success page, try linking to your custom success page from somewhere on the same page as the form. Use the same exact path in your test link as you’re trying to use for the
action attribute, and make sure the link works there before digging further into your form.
# Extra spam prevention
If you’re adding a honeypot field or reCAPTCHA 2 challenge, you can check the form detail page to confirm whether or not the Extra spam prevention has been successfully enabled.
# Missing submissions
Here are some common causes and solutions for missing form submissions.
# Test submissions flagged as spam
If you’re sending test submissions of your form and not finding them in your Verified submissions list, it’s possible they’re getting flagged as spam by Akismet. Use the menu above the list to switch to Spam submissions and then recheck for your tests.
To avoid having your tests flagged as spam in the first place, we recommend you
- enter a real email address instead of a fake one such as email@example.com.
- write some full sentences in any textareas rather than a few nonsense characters.
- spread out the rate of submissions from a single IP address.
# Form detection disabled
If you’re not finding new form submissions in your Verified submissions list for updated or newly added forms, ensure that form detection is enabled for your site. Go to Settings > Build & deploy > Post processing > Form detection to review the setting.
# Missing data from old submissions
If you recently changed the name or type of a form field, data for that field from old submissions will no longer appear in the Netlify UI. This is because the Netlify UI only shows the form fields and data that correspond to the last deployed version of your form.
Fortunately, all of your previous submission data are still available through the Netlify API. You can request form data with the listFormSubmissions endpoint.
If you would like to review the data from both the old and current form fields in the Netlify UI, we recommend that you mark old form fields as “hidden” instead of removing or replacing them entirely.
