How to Test Twitch Webhooks
Twitch EventSub webhooks notify your app about stream, channel, and subscription events for broadcaster integrations.

Twitch Official Webhook Docs1. Twitch Webhook Events
Twitch can send the following webhook events to your endpoint:
stream.onlinestream.offlinechannel.followchannel.subscribechannel.subscription.giftchannel.cheerchannel.raidchannel.update2. Set Up a Test Endpoint with HookRay
Follow these steps to start receiving Twitch webhooks for testing:
- Go to HookRay and click "Start Testing — Free" to get your unique webhook URL.
- Copy the URL (e.g.,
https://h.hookray.com/abc123). - In your Twitch dashboard, navigate to the webhook settings and paste the HookRay URL as your endpoint.
- Select the events you want to receive (see list above).
- Trigger a test event — HookRay will show the incoming webhook in real-time.
3. Sample Twitch Webhook Payload
Here's an example of what a Twitch webhook payload looks like:
{
"subscription": {
"id": "f1c2a387-161a-49f9-a165-0f21d7a4e1c4",
"type": "channel.follow",
"version": "2",
"condition": {
"broadcaster_user_id": "12345"
}
},
"event": {
"user_id": "67890",
"user_login": "viewer_fan",
"user_name": "Viewer_Fan",
"broadcaster_user_id": "12345",
"followed_at": "2026-03-20T15:30:00.000Z"
}
}4. Frequently Asked Questions
How do I test Twitch webhooks without deploying?
Use HookRay to get an instant public webhook URL. Paste it into your Twitch dashboard's webhook configuration, trigger an event, and watch the payload arrive in real time. No code, no ngrok, no deployment required. The free tier captures 100 requests per month and works on all Twitch event types.
Why aren't my Twitch webhooks arriving?
The four most common causes: (1) the endpoint URL isn't publicly accessible — Twitch can't reach localhost; (2) the wrong events are subscribed in your Twitch dashboard; (3) signature verification is rejecting the request before your handler runs; (4) Twitch can't reach your server because of a firewall, expired SSL certificate, or wrong DNS. Use HookRay's URL to isolate which of these four is failing — if HookRay receives the webhook, the problem is in your handler. If HookRay doesn't, the problem is in Twitch configuration.
Why am I getting 400 or 500 errors from my Twitch webhook?
Twitch reports the response status your endpoint returned. HookRay accepts any payload and returns 200 OK by default, so if you see 400/500 in your Twitch dashboard while pointing at HookRay, the issue is in Twitch's configuration (wrong event, malformed signing secret, etc.). If you point at your own endpoint and get 400/500, the issue is in your handler — capture the request with HookRay, replay it locally, and debug from the captured payload.
How do I verify Twitch webhook signatures?
Twitch signs each webhook request with a shared secret. Capture the raw headers and body using HookRay, then verify the signature in your application using Twitch's SDK or a standard HMAC library. Once verification works against HookRay-captured data, you can safely deploy. Twitch's docs (linked above) cover the exact signing algorithm.
Can I replay a captured Twitch webhook?
Yes — HookRay's replay feature re-sends any captured webhook to a different endpoint with one click. This is the fastest way to fix a buggy handler: capture the payload once, fix your code, and replay until it works. No need to re-trigger the event in Twitch.
