Frequently Asked Questions
- How do I get a unique webhook URL?
- Click 'Create Endpoint' and a unique URL is generated instantly. Copy it and use it as your webhook destination in any service.
- Can I replay captured webhooks?
- Yes. Select any captured request, switch to the Replay tab, enter a target URL, and click Send. The original method, headers, and body are preserved.
- Can I forward webhooks to localhost?
- Yes. Set a forwarding URL for your endpoint (e.g., http://localhost:3000/api/webhook) and all incoming webhooks will be automatically forwarded there in real-time.
- How long are requests retained?
- Free endpoints retain requests for 1 hour with up to 100 requests stored. Pro users get 24-hour retention with up to 500 requests.
- Are webhook payloads private?
- Yes. Webhook data is stored temporarily in Redis (in-memory) and automatically deleted after the retention period. Data is never persisted to disk or shared with third parties.
- How do I test Stripe webhooks with this?
- Create an endpoint, copy the URL, then go to Stripe Dashboard → Developers → Webhooks → Add endpoint. Paste your URL, select the events you want to receive, and trigger a test event.
- What HTTP methods are supported?
- All standard HTTP methods: GET, POST, PUT, PATCH, DELETE, and HEAD. The tool captures the full request regardless of method.
- Is there a request size limit?
- Request bodies up to 1 MB are captured in full. Larger payloads are accepted but the body is truncated to 1 MB in the stored capture.
