FormsFortReserved Fields
Web3Forms-compatible hidden fields and captcha tokens supported by the public endpoint.
Reserved Fields
FormsFort forwards custom fields and handles reserved fields separately. Routing uses access_key or apikey. Email behavior can be controlled with email, subject, from_name, replyto, and paid/manual ccemail.
When from_name is omitted, new forms use the Web3Forms-compatible default sender name Notifications.
Blank subject, from_name, and replyto values are ignored so empty hidden fields do not replace safe form defaults.
Form control fields
Form posts can include redirect for a validated success redirect, botcheck for honeypot spam rejection, attachment for uploads, and webhook for paid/manual per-submit webhook delivery.
Captcha tokens
Captcha providers use the Web3Forms-compatible token names:
| Provider | Token field name |
|---|---|
| hCaptcha | h-captcha-response |
| Google reCAPTCHA v3 | recaptcha_response |
| Cloudflare Turnstile | cf-turnstile-response |
