Send. Catch. Understand.
Everything you need to go from your first request to a replayed webhook.
Quick start
Sign in with Google or GitHub. A private workspace is created for you automatically. Open Webhook Inbox, choose New endpoint, and copy its delivery URL on hooks.hookripple.com. Paste that URL into any service that sends webhooks, or use it from the API client as described below.
The connected workflow
Select your endpoint in the API Client, put {{webhook_url}} in the callback field of a request, and send it. The response appears in the request pane while the resulting webhook streams into the inbox, linked by an explicit correlation ID. Try callback loop runs the same flow against a built-in synthetic integration so you can see it end to end without an external service.
Execution modes
The cloud relay processes your request, including target credentials, on HookRipple servers. It accepts public HTTP and HTTPS destinations on ports 80 and 443, does not follow redirects, and blocks private networks. Browser-direct requests are sent by your own browser, obey CORS and browser header restrictions, omit cookies and are not stored in server history. Localhost and private targets need a future local agent.
Variables and secrets
The selected environment provides variables. The reserved {{webhook_url}} value always comes from the selected endpoint and cannot be overridden. Missing values or reference cycles stop execution before anything is sent. Secret values are encrypted at rest and omitted from exports by default. Anyone who can use a secret can send it to a destination, so treat use permission as seriously as reveal permission.
Callbacks and replay
Raw body bytes are captured at the ingress boundary and encrypted separately from parsed views. Proxies may normalise header names, combine repeated headers and decode transport framing. Every retry from a provider is kept; a matching body is labelled a likely duplicate, never discarded. Replay is always explicit: edit, review, confirm. It may cause real side effects, and original provider signatures may not validate.
Limits during beta
1 MiB inbound and request bodies, 5 MiB responses, 30 seconds per outbound request, 24-hour payload retention (adjustable in Settings), 10 endpoints, 100 MiB captured body storage, 60 requests per minute per operation category and 3 concurrent relay runs per workspace.
What is coming
Shared workspaces and invitations, longer retention, automation tokens, a local agent for private targets, broader import formats and scheduled requests are on the roadmap. Beta users hear about new features first.
