Description

Kainoto Webhook for Contact Form 7 is a lightweight WordPress plugin that extends Contact Form 7 functionality by sending form submission data to specified webhook URLs. The plugin operates asynchronously, ensuring your website’s performance isn’t affected by external API response times.

Key Features

  • Asynchronous Processing: Sends webhook data without waiting for response, maintaining optimal site performance
  • Easy Configuration: Simple webhook URL setup directly in Contact Form 7 admin panel
  • JSON Format: Sends form data in clean JSON format for easy processing
  • URL Validation: Built-in validation ensures only proper URLs are accepted
  • No Response Dependency: Fire-and-forget approach prevents external service issues from affecting your forms
  • Lightweight: Minimal code footprint with no unnecessary bloat

Perfect For

  • CRM integrations
  • Email marketing services
  • Custom analytics tracking
  • Third-party notification systems
  • API-based workflow automation
  • Real-time data synchronization

How It Works

  1. Install and activate the plugin
  2. Edit any Contact Form 7 form
  3. Navigate to the new “Webhook” tab
  4. Enter your webhook URL
  5. Save the form

That’s it! Now every form submission will automatically send the data to your specified webhook URL in JSON format.

Technical Details

  • Hooks into Contact Form 7’s submission process after validation but before email sending
  • Sends POST requests with JSON payload containing all form field data
  • Uses WordPress HTTP API for reliable delivery
  • 15-second timeout with non-blocking execution
  • Sanitizes and validates all webhook URLs

$json = file_get_contents(‘php://input’);
$data = json_decode($json, true);

// Process form data
foreach($data as $field => $value) {

Frequently Asked Questions

Does this plugin slow down my website?

No! The plugin uses asynchronous (non-blocking) requests, meaning it doesn’t wait for the webhook response. Your forms submit normally while the webhook data is sent in the background.

What data format is sent to the webhook?

All form field data is sent as JSON in the request body. The Content-Type header is set to “application/json; charset=UTF-8”.

What happens if my webhook URL is down?

Nothing happens to your form functionality. Since the plugin doesn’t wait for responses, webhook failures won’t affect your Contact Form 7 submissions or user experience.

Can I use multiple webhook URLs per form?

Currently, each form supports one webhook URL. If you need multiple endpoints, consider using a webhook relay service or setting up your webhook to forward data to multiple destinations.

Is the webhook data secure?

The plugin sends data exactly as submitted through your contact form. Ensure your webhook endpoint uses HTTPS and implements proper security measures on your end.

Can I customize the data sent to the webhook?

The plugin sends all form field data as submitted. For custom data manipulation, you can modify the webhook endpoint to process the received JSON data as needed.
