Why people use Webhook.site

Webhook.site for Debugging API Callbacks

This Connector changes that by bringing the dashboard into your chat. You tell your agent to create a token, and it gives you the URL. When the hit comes in, you ask the agent to show you the payload. No tabs, no hunting for logs, just direct answers.

What Vinkius changes

You get a way to debug and simulate webhooks using only natural language.

Use it from Claude, ChatGPT, Cursor or another AI client you already have.

One account · 5,900+ Connectors

  1. Real-world use case 01

    Debugging a Stripe payment callback

    A developer asks the agent to create a token for 'stripe-test' and wait for a webhook.

  2. Real-world use case 02

    Simulating a 500 error from a third party

    A QA engineer needs to see how the app handles a crash.

  3. Real-world use case 03

    Managing environment-wide variables

    A dev uses create_global_variable to store a shared secret across multiple webhook tests, ensuring the agent can use the same value in different scenarios without re-typing it.

Before you connect

Questions about Webhook.site.

The practical details behind the request, access and result.

Can I use Webhook.site MCP to see what data my app is sending?

Yes. You can use it to capture and inspect any outgoing HTTP request. Your agent can pull the headers and the raw JSON payload so you can see exactly what your app is doing.

How do I use Webhook.site MCP to test a failed API call?

You can use it to simulate failures easily. Just tell your agent to set a dynamic response with a specific error code, like a 404 or 500, and a custom message.

Is Webhook.site MCP good for debugging Stripe or Twilio webhooks?

It's perfect for that. You can create a unique URL for each integration, watch the incoming data in real-time, and verify that the payloads match what you're expecting from those providers.

Can Webhook.site MCP help me manage multiple test URLs at once?

Yes, it can. Your agent can list all your active tokens, create new ones with specific aliases, and even delete old ones to keep your workspace organized.

Does Webhook.site MCP support global variables for my tests?

Yes, it does. You can create and update global variables to store state or configuration data that your agent can access across different webhook test runs.

Can I use Webhook.site MCP to clear out my request history?

You can. If your logs get too cluttered during a long debugging session, just ask your agent to delete the requests for a specific token to start with a clean slate.

How can I create a temporary webhook URL that expires after one hour?

Use the create_token capability and set the expiry parameter to 3600 seconds. You can also add an alias to make the URL easier to identify.

Can I see the headers and body of the requests sent to my webhook?

Yes! Use the get_requests capability with your Token ID. It will return a list of captured requests including full headers, query strings, and the raw payload content.

Is it possible to make the webhook return a specific JSON response?

Absolutely. Use the set_response capability to define a custom content (base64 encoded), status code, and JSON headers for any specific request received by your token.
