HTML Integration

Complete guide to integrating 4Form forms with HTML, JavaScript, Python, and cURL.

Form Integration

The Form Integration section provides you with everything needed to embed your forms into websites, applications, or backend services. 4Form supports multiple integration methods to fit your technical requirements.

Integration Methods

4Form provides ready-to-use code snippets for the following technologies:

  • HTML Form: Traditional form submission
  • JavaScript/AJAX: Asynchronous form submission
  • Python Requests: Server-side integration
  • cURL Commands: Command-line and script integration

HTML Form Integration

Basic HTML Implementation

The HTML integration provides a complete form snippet that you can embed directly into any website:

<form action="https://your-form-url.com/submit" method="POST">
  <input type="text" name="name" placeholder="Your Name" required>
  <input type="email" name="email" placeholder="Your Email" required>
  <textarea name="message" placeholder="Your Message"></textarea>
  <button type="submit">Submit</button>
</form>

Benefits:

  • Works on any website without JavaScript
  • Traditional form submission with page reload
  • Compatible with all browsers
  • Simple to implement

JavaScript/AJAX Integration

Asynchronous Form Submission

For modern web applications that require seamless user experience:

async function submitForm(formData) {
  try {
    const response = await fetch('https://your-form-url.com/submit', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(formData)
    });
    
    if (response.ok) {
      console.log('Form submitted successfully');
    }
  } catch (error) {
    console.error('Submission failed:', error);
  }
}

Benefits:

  • No page reload required
  • Better user experience
  • Real-time validation possible
  • Custom success/error handling

Python Integration

Server-Side Form Submission

Perfect for backend services, automation scripts, or data processing:

import requests

def submit_form_data(data):
    url = "https://your-form-url.com/submit"
    response = requests.post(url, json=data)
    
    if response.status_code == 200:
        print("Form submitted successfully")
    else:
        print(f"Submission failed: {response.status_code}")

# Example usage
form_data = {
    "name": "John Doe",
    "email": "john@example.com",
    "message": "Hello from Python!"
}
submit_form_data(form_data)

Use Cases:

  • Automated data collection
  • Backend service integration
  • Batch form submissions
  • Data migration scripts

cURL Integration

Command-Line Form Submission

Ideal for testing, shell scripts, and automation:

curl -X POST https://your-form-url.com/submit \
  -H "Content-Type: application/json" \
  -d '{
    "name": "John Doe",
    "email": "john@example.com",
    "message": "Hello from cURL!"
  }'

Use Cases:

  • API testing
  • Shell script automation
  • CI/CD pipeline integration
  • Quick form testing

Implementation Steps

1. Get Your Form URL

Each form has a unique submission URL that you'll find in the Integration section of your form settings.

2. Choose Your Method

Select the integration method that best fits your technical stack and requirements.

3. Copy the Code

All code snippets are pre-configured with your form's unique URL. Simply copy and paste into your project.

4. Customize as Needed

Modify the code to match your styling, validation requirements, and error handling preferences.

5. Test Your Integration

Always test your form integration before going live to ensure proper data submission.

Best Practices

  • Always validate data on both client and server side
  • Handle errors gracefully with user-friendly messages
  • Test thoroughly across different browsers and devices
  • Use HTTPS for secure data transmission
  • Implement rate limiting to prevent spam submissions

Troubleshooting

Common Issues

  • CORS errors: Ensure your domain is whitelisted in form settings
  • Failed submissions: Check network connectivity and form URL
  • Missing data: Verify field names match your form configuration
  • Timeout errors: Consider implementing retry logic for network issues
