Frequently Asked Questions
Q.What is a webhook?
A webhook is an HTTP callback — an automated message sent from one application to another when an event occurs. For example, when a payment succeeds in Stripe or a push is made on GitHub, a webhook sends a POST request to your specified webhook URL with the event data.
Q.How do I test a webhook?
Use this webhook tester to generate a temporary webhook URL. Set that URL as the callback endpoint in your service (Stripe, GitHub, Discord, etc.). When the service fires the webhook, the incoming request is captured here with full headers, body, and query parameters so you can inspect it.
Q.How is this different from webhook.site?
This webhook tester runs entirely in your browser with no signup required. It's a lightweight, privacy-focused alternative to webhook.site and other request catcher services for inspecting webhook payloads during development.
Q.Can I test Discord webhooks with this tool?
Yes. You can compose and send test payloads to Discord webhook URLs, or use the generated endpoint to inspect incoming webhook requests from Discord bots and integrations.
Q.What is an incoming webhook?
An incoming webhook is a URL endpoint that accepts HTTP POST requests from external services. Apps like Slack, Discord, and Microsoft Teams use incoming webhooks to receive messages and notifications from third-party services.
Q.Can I customize the webhook response?
Yes. You can set the HTTP status code and response body that the endpoint returns to the sender, letting you simulate different server behaviors for your webhook test scenarios.
Q.What is a webhook URL?
A webhook URL is the endpoint address where webhook payloads are sent. When you configure a webhook in a service like Stripe or GitHub, you provide a webhook URL that receives the HTTP POST requests containing event data.
Q.How long are captured webhooks stored?
Captured webhooks are stored in your browser session only. They persist until you close the tab or clear them manually. No data is sent to any server — everything stays on your device.
