# **Test Jira Webhooks Locally**

Test Jira webhooks locally and receive them on localhost without deploying. Inspect the real payload, forward to your handler, and verify the signature.

![Test Jira Webhooks Locally (Receive Jira Webhooks on localhost)](https://webhookrelay.com/blog/receive-jira-webhooks-locally/images/blog/heroes/localhost.jpg)

You are building a Jira integration and you need to watch your handler react to a real event. The problem hits immediately: Jira will only POST to a **public URL**, and your handler is running on `localhost:8080`. Jira has no way to reach it.

The usual workarounds are slow. Deploying to a staging environment for every code change kills your iteration speed. Copying a sample payload out of the docs into curl gives you a _guess_ at the real request, not the exact headers and body Jira actually sends. What you really want is to **test Jira webhooks locally** — real events, hitting your local handler, on a URL that does not change every time you restart.

This guide shows how to do exactly that.

## [Why testing Jira webhooks locally is tricky](#why-testing-jira-webhooks-locally-is-tricky)

A webhook is just an HTTP request that Jira sends to a URL when something changes. Jira lives on the public internet; your dev machine usually does not. It sits behind a router, a corporate firewall, or both, with no public IP and no inbound ports open.

So you need something in the middle: a public endpoint Jira can hit that relays each request down to your laptop without you opening a single firewall port. That is what [Webhook Relay](https://my.webhookrelay.com/register) does — and unlike a random tunnel URL, the endpoint is **stable**, so you configure Jira once and never touch it again.

## [Step 1: Inspect the real payload with Webhook Bin](#step-1-inspect-the-real-payload-with-webhook-bin)

Before you write any handler code, find out what Jira actually sends. Open the free [Webhook Bin](https://webhookrelay.com/blog/receive-jira-webhooks-locally/webhook-bin/) — no signup — and you get an instant public URL.

1. Copy the Webhook Bin URL.
2. In Jira, go to **Settings → System → Webhooks → Create a WebHook**, paste the URL, and pick the events and a JQL filter. For signed deliveries, register a **dynamic** webhook via the REST API with a `secret`.
3. Trigger a real event and inspect the captured request.

You will see the full body and every header. The body is JSON with a `webhookEvent` field plus the changed `issue`, `comment` or `user` objects and a `changelog` for updates. You can also narrow deliveries with a JQL filter when you create the webhook.

Now you know the exact shape of the data before writing a line of code. For more on this approach, see [How to test webhooks](https://webhookrelay.com/blog/receive-jira-webhooks-locally/blog/how-to-test-webhooks/) and [What is a webhook](https://webhookrelay.com/blog/receive-jira-webhooks-locally/blog/what-is-webhook/).

## [Step 2: Forward the events to localhost with the relay agent](#step-2-forward-the-events-to-localhost-with-the-relay-agent)

Once you know the payload, route those same events into your local handler. [Sign up for Webhook Relay](https://my.webhookrelay.com/register), install the `relay` agent (CLI or Docker), and create a bucket — say `jira`. The bucket gives you a stable public input endpoint.

Start forwarding to your local server:

```
relay forward --bucket jira http://localhost:8080/webhook
```

The agent opens an **outbound** connection to Webhook Relay and streams every incoming request down to `http://localhost:8080/webhook`. Because the connection is outbound, there are **no firewall ports to open and no public IP needed** — this works from your laptop, behind a corporate proxy, or inside a Kubernetes cluster. Running in Docker? The same command works in the official `webhookrelay/webhookrelayd` image. Full details are in the [localhost forwarding docs](https://webhookrelay.com/blog/receive-jira-webhooks-locally/docs/webhooks/internal/localhost/).

Now point the Jira webhook at your Webhook Relay endpoint (or create it there from the start), trigger an event, and watch it arrive on `localhost`.

## [Jira-specific configuration and quirks](#jira-specific-configuration-and-quirks)

A few Jira details worth knowing:

- **Two ways to register:** **Settings → System → Webhooks** in the admin UI, or the REST API for **dynamic** webhooks (which support a signing `secret`).
- **JQL filter:** scope deliveries to specific projects or issue types with a JQL filter so you don't get the whole instance's traffic.
- **Payload shape:** JSON with `webhookEvent`, the changed entity, and a `changelog` on updates.
- **Signing varies:** dynamic webhooks sign with `X-Hub-Signature`; classic ones don't — see the verification step.

## [Step 3: Verify the Jira webhook signature](#step-3-verify-the-jira-webhook-signature)

How you verify depends on how the webhook was created. If you register a **dynamic webhook** through Jira's REST API with a `secret`, Jira signs the raw body with **HMAC-SHA256** and sends it as `sha256=...` in the **`X-Hub-Signature`** header — recompute and compare in constant time. Classic webhooks created in the admin UI are **not** signed; for those, put a hard-to-guess secret in the webhook URL and check it, and/or restrict inbound traffic to Atlassian's IP ranges.

To sanity-check an HMAC implementation, paste a captured body, your secret, and the received signature into the free [HMAC signature verifier](https://webhookrelay.com/blog/receive-jira-webhooks-locally/hmac-verification/). For language-specific code and the common pitfalls (reading the body _after_ a JSON parser has already consumed it, timing-safe comparison), read [Verify a webhook signature](https://webhookrelay.com/blog/receive-jira-webhooks-locally/blog/verify-webhook-signature/).

## [Replay and iterate](#replay-and-iterate)

This is where local development gets fast:

- **Replay from Webhook Relay** — past requests are stored on your bucket, so you can resend a captured event against your handler without touching Jira at all.
- **Iterate on your handler** by editing code and replaying the same delivery until it behaves correctly. No commits, no pushes, no deploys just to test a single code path.
- **Keep `relay forward` running** while you work — events stream straight to `localhost` as you trigger them in Jira.

Because the Webhook Relay endpoint is stable, you can stop and restart the agent, reboot your machine, or come back next week — the Jira configuration never needs to change.

## [Get started](#get-started)

1. Inspect the real payload in the free [Webhook Bin](https://webhookrelay.com/blog/receive-jira-webhooks-locally/webhook-bin/) — no signup needed.
2. [Create a Webhook Relay account](https://my.webhookrelay.com/register), install the agent, and run `relay forward --bucket jira http://localhost:8080/webhook`.
3. Point your Jira webhook at the stable endpoint, trigger an event, and watch it hit `localhost`.

You will be testing real Jira events against your local handler in a few minutes — no deploys, no open firewall ports, and a URL you configure exactly once.
