Key features

  1. 01Verify admin webhook signatures
  2. 02Distinguish admin and app verification
  3. 03Identify events in JSON payloads
  4. 04Find handler and test examples

Use cases

  1. 01Investigate Jira signature failures
  2. 02Build issue and comment event handlers
  3. 03Register and test Jira webhook endpoints

Install

Jira Webhooks

When to Use This Skill

  • How do I receive Jira webhooks?
  • How do I verify Jira webhook signatures?
  • How do I handle jira:issue_created or jira:issue_updated events?
  • Why is my Jira webhook signature verification failing?
  • Understanding Jira event types and payloads

Verification (core)

For admin webhooks (created on the Jira admin WebHooks page or via POST /rest/webhooks/1.0/webhook) saved with a secret, Jira Cloud signs the raw request body with HMAC-SHA256 keyed on that secret. It sends the digest in the X-Hub-Signature header (not X-Hub-Signature-256) using the WebSub method=signature format, i.e. sha256=<hex>. Verify the raw body before parsing JSON and compare timing-safe.

Admin webhooks without a secret are unsigned. App webhooks use a different scheme: Connect descriptor webhooks get a JWT signed with the app's sharedSecret, and OAuth 2.0 dynamic webhooks (POST /rest/api/3/webhook) get a bearer JWT signed with the app's client secret, both in the Authorization header. See references/verification.md.

Node:

const crypto = require('crypto');

function verifyJiraWebhook(rawBody, signatureHeader, secret) {
  const [method, sig] = (signatureHeader || '').split('=');
  if (method !== 'sha256' || !sig) return false;
  const expected = crypto.createHmac('sha256', secret).update(rawBody).digest('hex');
  try {
    return crypto.timingSafeEqual(Buffer.from(sig, 'hex'), Buffer.from(expected, 'hex'));
  } catch {
    return false; // length mismatch = invalid
  }
}

Python:

import hmac, hashlib

def verify_jira_webhook(raw_body: bytes, signature_header: str, secret: str) -> bool:
    method, _, sig = (signature_header or "").partition("=")
    if method != "sha256" or not sig:
        return False
    expected = hmac.new(secret.encode(), raw_body, hashlib.sha256).hexdigest()
    return hmac.compare_digest(sig, expected)

For complete handlers with route wiring, event dispatch, and tests, see:

Common Event Types

Jira does not send an event-type header. The event name is in the JSON body under the webhookEvent field.

Event (webhookEvent)Triggered When
jira:issue_createdAn issue is created
jira:issue_updatedAn issue is edited or transitioned
jira:issue_deletedAn issue is deleted
comment_createdA comment is added to an issue
comment_updatedA comment is edited
comment_deletedA comment is deleted
worklog_createdA worklog is logged on an issue

For the full event reference, see Jira webhook events.

Important Headers

HeaderDescription
X-Hub-SignatureHMAC SHA-256 signature, formatted sha256=<hex> (admin webhooks with a secret)
AuthorizationJWT on Connect descriptor and OAuth 2.0 app webhooks (the docs describe it only for app webhooks)
X-Atlassian-Webhook-IdentifierUnique delivery identifier

Environment Variables

JIRA_WEBHOOK_SECRET=your_webhook_secret   # The `secret` set on the admin webhook

Local Development

# Start tunnel (no account needed)
npx hookdeck-cli listen 3000 jira --path /webhooks/jira
