The Webhook Testing Tool Built for Teams, Not Just Developers
Every payload your services fire lands in a permanent, authenticated inbox — inspectable, shareable, and visible to your entire team in real time. No more lost payloads. No more "did the webhook fire?" in Slack.
Works with any HTTP client · Stripe · GitHub · Shopify · Discord · Slack · Microsoft Teams · Any REST service
Webhooks fail silently. That's the real problem.
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
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
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
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 Inbox captures every payload permanently, validates your structure, and gives your whole team a shared view — from the first request.
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 Inbox 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.
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 has its own webhook and inbox — fully sealed. Nothing bleeds across.
SECURITY
Every endpoint authenticated. Every project isolated.
Unlike throwaway webhook URLs, every Zunoy Webhook Inbox endpoint requires authentication. Your payloads are never publicly exposed.
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.
Four Steps to your First Captured Webhook
Create a Project
Give your project a name and choose your project type — Custom, Discord, Slack, or Microsoft Teams. Project type determines how Sandbox validates incoming payloads. Choose carefully — it's locked after creation.
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.
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.
Inspect everything instantly
Every payload that hits your endpoint appears in your inbox immediately — HTTP method, full headers, query params, raw body, timestamp, and response code. Your entire team sees it at the same time.
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 Inbox handles incoming payloads. Selected once at creation. Locked after.

Drop-in endpoint replacement. Works with any HTTP client.
Replace your real webhook destination with your Zunoy 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 - /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 webhook payload that lands in your inbox 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.
One webhook inbox your whole team debugs together
Webhook debugging shouldn't live on one developer's machine. 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.
Know the moment a webhook lands - without watching the inbox
Connect your Webhook Inbox 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.

What teams actually use Webhook Inbox for
Built for teams, not just individual developers
Most webhook testing tools are designed for a single developer in a single session. Zunoy Webhook Inbox is built for teams — with authentication, isolated projects, platform validation, and a payload history your whole team can rely on sprint after sprint.

The things developers actually ask about Webhook Inbox
What is Zunoy Webhook Inbox?
A permanent, authenticated webhook endpoint for development and staging teams. Your services send payloads to your Zunoy URL instead of a real destination. Every payload lands in your team's shared project inbox — inspectable, retainable, and shareable with a single link.
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.
What happens if I send a malformed Discord, Slack, or Teams payload?
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.
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 many webhook endpoints can I create per project?
This depends on your plan. Check the pricing page for specifics per tier.
Every webhook your services fire. Captured. Permanent. Shared.
