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. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Kainoto Webhook for Contact Form 7” is open source software.
