Webhook Testing

RequestBin

People search for RequestBin when they need a fast place to send an HTTP request and see exactly what arrived: method, path, headers, query string, content type, and body.

FastHook covers that request-bin workflow with temporary request bins, then gives you a clean upgrade path when the same webhook should become a reliable routed flow with destinations, retries, replay, and delivery logs.

What RequestBin means

RequestBin is shorthand for a disposable request collector. It is useful when you are wiring up Stripe, GitHub, Shopify, Slack, an internal service, or a custom webhook sender and need to confirm the raw request before building the receiver.

FastHook request bins

  • Create a temporary public URL for webhook and HTTP request tests.
  • Inspect request method, path, query params, headers, and payload body.
  • Use the bin for quick provider setup checks or cURL experiments.
  • Copy sanitized request evidence when a teammate or support thread needs context.
  • Move from temporary capture to a production FastHook source when the stream matters.

Example RequestBin-style test

curl -X POST "https://hook-xxxxxx.fasthook.io/" \
  -H "Content-Type: application/json" \
  -H "X-Event-Type: test.created" \
  -d '{
    "id": "evt_requestbin_001",
    "type": "test.created",
    "source": "requestbin"
  }'

When a bin is not enough

A request bin tells you what arrived. A webhook gateway tells you what happened next. When the test becomes a real integration, FastHook can route the captured stream to HTTP, Slack, Google Sheets, email, Telegram, R2, S3, mock receivers, or local CLI destinations, with retry and replay evidence for failures.

FAQ

What is RequestBin used for?

RequestBin is commonly used as a temporary HTTP endpoint for capturing requests, inspecting webhook payloads, checking headers, and debugging whether a sender is posting the expected data.

Does FastHook have a RequestBin-style tool?

Yes. FastHook request bins create temporary webhook inboxes for request capture and inspection. The same test traffic can later be moved into a production source with routing, retries, replay, and destinations.

When should I use a request bin instead of a production source?

Use a request bin when you need a short-lived test URL for payload discovery, provider setup checks, support handoff, or cURL experiments. Use a production source when the webhook stream needs long-lived delivery, authentication, destinations, retries, or replay.
