Troubleshooting

First check the spam or promotions folder of the email client — that's the most common cause. If it's not there, open your form in the dashboard, Settings tab, and confirm the target emails are correct: a typo there means the submission is processed but never reaches anywhere. If your plan requires domain restriction and your form has an allowed-domains list configured, check that the domain you're submitting from is in that list — if it isn't, the API responds 403 instead of accepting the submission, and the email never gets sent.

The hidden botcheck field is the anti-spam trap (honeypot): it must always arrive empty. A very common cause of false positives is a password manager that autofills every field in the form, including this one. Every Farvane snippet already includes autocomplete="off" and tabindex="-1" on that field precisely to prevent this — if you copied the form a while ago or edited it by hand, check that both attributes are still there.

This code covers two different limits, depending on the message. "Demasiadas peticiones" ("too many requests") is the 20-requests-per-minute limit for the same access_key + IP — an anti-abuse protection that resolves itself after a minute. "Límite de envíos mensuales alcanzado" ("monthly submission limit reached") means your form used up your plan's monthly submission quota this month.

Check Billing & Usage in the dashboard

The API returns 400 with one of these messages in two cases: the access_key is not a valid UUID (check that you copied it in full, with no extra spaces or characters), or it belongs to a form that no longer exists, for example if you deleted it from the dashboard. Copy the access_key again from the Settings tab of the corresponding form.
