Just here to say me to, and all of the sudden hitting all of the same problems when trying to edit the literal dawn form require the name field in addition to the email field.
If you had any luck figuring it out, please share.
Topic summary
Issue: Users implementing custom Shopify Forms with CAPTCHA enabled encounter a 404 error after completing the CAPTCHA challenge. The form redirects to /challenge URL, which doesn’t exist, breaking the submission flow. Additionally, the FORM object isn’t returning expected attributes like ?posted_successfully.
Affected Users: Multiple developers report identical issues when integrating Shopify Forms into custom themes, despite following official documentation. The same setup works correctly with Shopify’s Dawn theme.
Shopify Support Response: Unhelpful—directed users back to community forums without providing solutions.
Working Solution Provided:
WyldCode shared a technical fix involving:
- Unbinding Shopify’s default submit hook using jQuery
.off('submit') - Attaching custom submit callback
- Manually calling RecaptchaV3 JS API to fetch validation token
- Adding the
g-recaptcha-responsetoken to serialized form payload - Submitting via AJAX to the form action URL
Key Technical Detail: Shopify automatically adds recaptcha validation tokens before submission. Custom implementations must replicate this by manually fetching and including the token in the request payload.
Status: Solution proposed but not yet verified by affected users. Thread remains open for confirmation and further discussion.
