My form submissions are not appearing

1. Verify the form action is exactly https://formstodb.com/api/submit
2. Verify method="POST" is set on the form
3. Verify the hidden field name is exactly _key (lowercase, with underscore)
4. Verify the key value matches the one in your FormsToDB dashboard
5. Check that the form is not being intercepted by JavaScript before submission
6. Open browser DevTools → Network → submit the form → look for the POST request to formstodb.com

I'm getting a 401 error

The API key is invalid or doesn't exist. Double-check by copying the key directly from Dashboard → Forms. Keys are case-sensitive.

I'm getting a 429 error

You've reached your monthly submission limit. Upgrade your plan in Dashboard → Billing or wait until the 1st of next month when limits reset.

Leads appear but some fields are missing

Only fields with a name attribute are captured. Check that all your inputs have a name attribute. Fields named _key, _token, _redirect and _method are reserved and excluded.

Email notifications are not arriving

• Check spam/junk folder
• Verify Email notify is toggled on for that specific form
• Ask your admin to verify SMTP settings in Admin → Email Settings
• Try sending a test email from Admin → Email Settings → Send Test

WhatsApp / Call buttons not working

• WhatsApp — the lead must have a phone number with country code (e.g. +34…)
• Call button — requires a Zapier webhook configured in Settings → Zapier. Your own phone number must also be set in Settings → Contact.

PayPal payment failing

• Verify credentials are correct in Admin → Payments → PayPal
• Ensure the mode matches your credentials (Sandbox credentials ≠ Live mode)
• Test credentials directly: curl -X POST https://api-m.sandbox.paypal.com/v1/oauth2/token -u "CLIENT_ID:SECRET" -d "grant_type=client_credentials"

Webhook not firing

• Verify the webhook URL is correct and publicly reachable
• Check Dashboard → Webhooks for the last_status column
• Use the Test button on the webhook to fire a test payload
• Check your receiving server's logs for the incoming request
