Webhook.site is a free third-party tool that lets you inspect and capture the raw HTTP requests sent from integrations, workflows, or custom API calls. Using Webhook.site makes it easy to debug webhook payloads, verify configuration, and troubleshoot issues before sending payloads to GHL Customer Care or your production endpoints.
Webhook.site instantly generates a unique test URL that collects all incoming webhook requests and displays them in real time. This makes it ideal for:
Capturing raw webhook payloads (headers, body, method)
Validating the structure of requests before sending them to your live endpoint
Troubleshooting integrations from Zapier, Make (Integromat), custom apps, or other automation tools
IMPORTANT: The steps in this article are for Advanced Integration and for informational purposes only.While we do not currently support or service either the Basic or Advanced API due to their complexity, we have many tools and groups to help you get started and connected! For assistance with APIs, you can join our Developer Council Slack Community here: https://ghlcustomercare.com/dev-slack We also hold a Developer Council Zoom Call once a month (second to last Friday) which you can find on the Events calendar here:https://ghlcustomercare.com/events

How It Works
Step 1: Visit Webhook.site
Open https://webhook.site in your browser. A unique test URL will be generated automatically.

If your tool or integration (like Zapier, Integromat, etc.) has a built-in testing tool, don't utilize this. Instead, use a real-world example. If the webhook is triggered when a form is submitted, go to the form and submit a test. If the automation fires when an action is performed in an external system, perform said action. This will provide you and your developers with the most accurate information, and will be incredibly valuable when troubleshooting advanced API-related issues.
Step5. Save your updates
Make sure to save your changes, then run whatever flow you have in place that would normally execute the webhook. If your tool or integration (like Zapier, Integromat, etc.) has a built-in testing tool, don't utilize this. Instead, use a real-world example.

This will provide you and your developers with the most accurate information, and will be incredibly valuable when troubleshooting advanced API-related issues.
Step 6. Review Payload Data
Next, you'll be presented with the raw data being received by GHL Customer Care anytime the webhook is executed. You can compare this with the information available on our API documentation websites to test your configuration.
