# Verification Steps for ContactForm API Integration

## Manual Verification Required

The ContactForm has been updated to call the real API route at `/api/contact` instead of simulating the submission.

### Test in Browser

1. **Navigate to**: http://localhost:3000/en/contact

2. **Test Successful Submission**:
   - Fill in all form fields (name, email, message)
   - Click "Send Message"
   - Verify: Success message appears
   - Verify: Form fields are cleared
   - Verify: No console errors

3. **Test Rate Limiting**:
   - Submit the form 5 times rapidly
   - On the 6th submission, verify:
     - Error message appears with rate limit warning
     - Message shows time until retry (e.g., "Too many requests. Please try again in 60 minutes.")
     - Form is still functional (not broken)

4. **Test Validation**:
   - Try submitting with empty fields
   - Verify validation errors appear
   - Try submitting with invalid email
   - Verify email validation error appears

5. **Test Error Display**:
   - Verify error messages are clearly visible
   - Verify error messages disappear on successful submission
   - Check that UI remains user-friendly

### Expected Behavior

- ✅ Form submits to `/api/contact` with POST request
- ✅ Success message displays on 200 response
- ✅ Rate limit error displays on 429 response with countdown
- ✅ Generic error message displays on other errors
- ✅ Form validation works before API call
- ✅ Loading state shows during submission
- ✅ Form is disabled during submission

### Changes Made

1. Added `errorMessage` state to store custom error messages
2. Replaced simulated API call with real `fetch()` to `/api/contact`
3. Added response status handling:
   - 200 (OK): Success message, clear form
   - 429 (Rate Limited): Display time until retry
   - 400/500: Display API error message
4. Improved error message display with custom messages
