Webhook Sandbox: The Webhook Testing Tool Built for Teams

Every payload your services fire lands in your permanent, authenticated Webhook Sandbox — inspectable, shareable, and visible to your entire team in real time. No more lost payloads. No more "did the webhook fire?" in Slack.

BEFORE ZUNOY SANDBOX

Webhooks fail silently. That's the real problem.

LOST PAYLOAD

Lost Payload

A webhook fired. Your handler threw an error. By the time you opened your logs, the payload was already gone. No body. No headers. Nothing to debug.

UNVERIFIED FIX

Unverified Fix

You think you fixed the bug. But without the original payload, you can't reproduce it to confirm. You're shipping a fix you can't actually verify.

PLATFORM SETUP

Platform Setup

Testing a Discord or Slack webhook means setting up a real server, a real bot, a real channel — just to check if your JSON structure is correct.

NO TEAM VISIBILITY

No Team Visibility

The payload landed in one developer's local tunnel. Nobody else on the team saw it. QA has no way to verify it. It's gone when the session ends.

Webhook Sandbox captures every payload permanently, validates your structure, and gives your whole team a shared view — from the first request.

WHAT IS WEBHOOK SANDBOX

A webhook testing tool your whole team can actually use

Most webhook debugging tools are built for one developer, one session, one throwaway URL.

Zunoy Webhook Sandbox is different. It's a permanent, authenticated webhook endpoint — built for teams working together on real projects. Your services point at Zunoy instead of a real destination, and every payload lands here, stays here, and is visible to your team simultaneously.

Organised into multiple isolated projects — one for your payment webhooks, another for GitHub integrations, another for your Discord bot — each with its own endpoints, its own token, and its own inbox. Nothing bleeds across.

Use the shared webhook tester to inspect webhook payloads, debug integration issues, validate Discord and Slack message structures, and share any payload with a single link — all without a real platform, a real server, or a real ngrok tunnel.

Payment Webhooks

Discord Bot

GitHub Integration

Each project in your Webhook Sandbox has its own webhook and inbox — fully sealed.

SECURITY

Every endpoint authenticated. Every project isolated.

Unlike throwaway webhook URLs, every Zunoy Webhook Sandbox endpoint requires authentication.

Authenticated Endpoints

Every webhook URL requires an Authorization token on every request. No token, no entry. Unauthenticated requests are rejected immediately — just like a production endpoint should behave.

Token-Based Access

Each project gets its own token. Rotate it anytime without changing your webhook URLs. Your services keep working. Your old token stops working.

Project Isolation

Payloads from Project A never appear in Project B. Every project is a fully sealed environment — separate URLs, separate inbox, separate token. Nothing bleeds across.

HOW IT WORKS

Four Steps to your First Captured Webhook

1

Create a Project

Give your project a name and choose your project type — Custom, Discord, Slack, or Microsoft Teams. Project type determines how your Webhook Sandbox validates incoming payloads. Choose carefully — it's locked after creation.

2

Create webhook endpoints inside the project

Add one or more webhook endpoints inside your project. Each gets a unique URL and path. Use different endpoints for different services, environments, or event types — all inside one project.

3

Point your service at the URL

Drop-in endpoint replacement. Swap your real webhook destination with your Zunoy URL. Works with any HTTP client, any language, any service. Your payload structure stays exactly the same.

4

Inspect everything instantly

Every payload that hits your endpoint appears in your Webhook Sandbox immediately — HTTP method, full headers, query params, raw body, timestamp, and response code. Your entire team sees it at the same time.

READ SETUP GUIDE

PROJECT TYPES

Custom webhooks or platform-specific validation - you choose at setup

Custom Webhook

Accepts any payload structure from any HTTP client. No structural validation — if the request is authenticated, it lands. Use this for internal services, custom REST integrations, payment processors, or any webhook that doesn't follow a specific platform format.

Discord

Validates incoming payloads against Discord's webhook structure. Malformed payloads — missing content, wrong field types, invalid embeds — are rejected with a clear reason. Test your Discord bot integrations without a real Discord server.

Slack

Validates incoming payloads against Slack's webhook format. Catches structural errors before they reach a real workspace. Test your Slack app integrations in complete isolation.

Microsoft Teams

Validates Teams connector payload structure. Rejects malformed cards and messages with a specific reason. Test your Teams integrations without a real Teams environment.

Your project type determines how Webhook Sandbox handles incoming payloads. Selected once at creation. Locked after.

INTEGRATION

Drop-in endpoint replacement. Works with any HTTP client.

For webhook testing, replace your real webhook destination with your Webhook Sandbox endpoint. Same payload. Same headers. One environment variable changed. That's the entire setup.

Select Platform Payloads - What lands in your inbox

curl --request POST \
  --url https://webhook.zunoy.com/project/hooks/events \
  --header 'Authorization: Bearer YOUR_PROJECT_TOKEN' \
  --header 'Content-Type: application/json' \
  --data '{
  "event": "user.signup",
  "user_id": "usr_1094",
  "email": "dev@example.com"
}'

These services send webhooks automatically. Point their destination URL at your Zunoy endpoint — everything below appears in your inbox exactly as received.

Use different webhook paths for different services in your Webhook Sandbox - /hooks/stripe, /hooks/github, /hooks/discord all inside the same project. Filter by path in your inbox.

PAYLOAD INSPECTOR

Everything your service sent. Nothing missing.

Every payload captured by the Webhook Sandbox webhook tester is fully visible — not just the body. The complete request, exactly as received.

If your service sent it, it's here. If something's wrong — the rejection reason tells you exactly what.

REAL-TIME

Every payload. The moment it arrives.

No refresh. No polling. Your whole team sees every incoming webhook simultaneously — method, source, body preview, and validation status. The 'did the webhook fire?' question stops here.

All payloads isolated per project · Shared with your team in real time · Retention based on your plan

SHARE ANY PAYLOAD

One link. Full payload. No account needed.

Generate a permanent read-only link for any received payload. Share it with a teammate, a stakeholder, or an external team — they see the full payload without needing access to your inbox.

What the link shows:

Full HTTP method, headers, query params, and body

Timestamp and response code

Validation status and rejection reason if applicable

Read-only — no inbox access, no project access granted

Your backend dev caught a malformed Stripe payload at 11pm. QA needs to review it tomorrow. One link. No screenshots. No copy-pasting JSON into Slack.

BUILT FOR TEAMS

One webhook inbox your whole team debugs together

Webhook testing for developers shouldn't live on one developer's machine. Webhook Sandbox gives your entire team visibility into the same inbox — in real time, from anywhere.

Multiple Isolated Projects

Create separate projects for different services, clients, or environments. Each project has its own endpoints, its own token, and its own inbox. A project for Stripe, another for GitHub. Another for your internal services. Completely isolated from each other.

Multiple Webhook Endpoints Per Project

Inside each project, create as many webhook endpoints as you need — different paths for different event types or services. Everything lands in the same project inbox, organised and filterable.

Shared Real-Time Inbox

Every team member sees the same live feed simultaneously. Your QA engineer, backend developer, and DevOps lead are all looking at the same payload at the same time. No more forwarding logs or sharing screenshots.

Payload Retention

Payloads don't disappear when someone closes their laptop. They stay in your inbox — available to review, share, and reference — for as long as your plan retains them. Your webhook history, preserved.

ALERTS

Know the moment a webhook lands - without watching the inbox

Connect your Webhook Sandbox to Slack, Discord, or Microsoft Teams and get instant notifications for every incoming payload — no need to keep a browser tab open. Perfect for real-time visibility during active integration testing.

USE CASES

What teams actually use Webhook Sandbox for

DEBUG

Debug Webhooks Without Losing the Payload

The payload fired. The handler broke. Instead of losing the evidence, your webhook catcher has the full payload — headers, body, timestamp — ready for your entire team to inspect and debug together.

See Debugging Guide
QA

Webhook Testing Tool for QA Teams

Run your integration test suite and validate that the right webhooks fired — right method, right body, right headers. QA and backend share the same inbox. No coordination overhead.

See QA Workflow Guide
STRIPE

Test Stripe Webhooks in Staging

Point your Stripe webhook destination at Webhook Sandbox during development. Inspect every payment_intent.succeeded or charge.failed event before your handler ever processes it.

See Stripe Testing Guide
GITHUB

GitHub Webhook Testing

Receive and inspect GitHub push events, pull request webhooks, and Actions triggers — without a live server or a running handler. Every payload visible the moment GitHub fires it.

See GitHub Testing Guide
DISCORD

Discord Webhook Testing

Test your Discord payload structure — content fields, embeds, username — without a real Discord server, a real bot, or a real channel. Webhook Sandbox validates the structure and tells you exactly what's wrong.

See Discord Testing Guide
SLACK

Slack Webhook Testing

Validate Slack message payloads — blocks, sections, attachments — without a live Slack workspace. Ship your Slack integration knowing the structure is correct before it touches a real channel.

See Slack Testing Guide
TEAMS

MS Teams Connector Testing

Test Teams connector cards and messages without a real Teams environment. Useful for enterprise teams building internal tooling on the Teams platform.

See Teams Testing Guide
INTERNAL

Internal Service-to-Service Validation

Verify that your microservices are firing the right events with the right payload structure. Each service gets its own webhook endpoint. Every event is logged and inspectable by the whole team.

COMPARISON

Built for teams, not just individual developers

Most webhook testing tools are designed for a single developer in a single session. Zunoy Webhook Sandbox is built for teams — with authentication, isolated projects, platform validation, and a payload history your whole team can rely on sprint after sprint.

FAQ'S

The things developers actually ask about Webhook Sandbox

What is Zunoy Webhook Inbox?

A permanent, authenticated webhook endpoint for development and staging teams. Your services can test webhooks without sending them to a real destination by using your Zunoy URL. Every payload lands in your team's shared project inbox — inspectable, retainable, and shareable with a single link.

What happens if I send a malformed Discord, Slack, or Teams payload?

Webhook Sandbox validates the payload structure against the platform's expected format. If required fields are missing or incorrectly typed, the request is rejected and the reason is logged in your inbox. You see exactly what was wrong — no guessing.

How many webhook endpoints can I create per project?

This depends on your plan. Check the pricing page for specifics per tier.

Is the webhook endpoint open or does it require authentication?

Authentication is required on every request. Every endpoint expects an Authorization token — requests without a valid token are rejected immediately. There are no open, publicly exposed endpoints.

Can I change my project type after creation?

No. Project type is selected at creation and locked. If you need a different project type, create a new project.

How long are payloads stored?

Retention is based on your plan. Payloads are automatically removed after your plan's retention window. Higher plans retain payload history longer.
