$npx -y skills add hookdeck/webhook-skills --skill jira-webhooksReceive and verify Jira Cloud webhooks. Use when setting up Jira webhook handlers, debugging signature verification, or handling issue and comment events like jira:issue_created, jira:issue_updated, jira:issue_deleted, comment_created, or comment_updated.

| 3 | ## When to Use This Skill |
| 4 | |
| 5 | - How do I receive Jira webhooks? |
| 6 | - How do I verify Jira webhook signatures? |
| 7 | - How do I handle `jira:issue_created` or `jira:issue_updated` events? |
| 8 | - Why is my Jira webhook signature verification failing? |
| 9 | - Understanding Jira event types and payloads |
| 10 | |
| 11 | ## Verification (core) |
| 12 | |
| 13 | Jira Cloud signs the **raw** request body with HMAC-SHA256 keyed on the secret |
| 14 | you set when registering a dynamic/OAuth 2.0 webhook, and sends the digest in the |
| 15 | `X-Hub-Signature` header using the WebSub `method=signature` format — i.e. |
| 16 | `sha256=<hex>`. Verify the raw body **before** parsing JSON and compare |
| 17 | timing-safe. |
| 18 | |
| 19 | > Only dynamic webhooks (registered via the REST API with a `secret`) are signed. |
| 20 | > Webhooks created in the Jira UI are **not** signed — they rely on HTTPS plus a |
| 21 | > hard-to-guess URL and an optional `?secret=` query parameter. See |
| 22 | > [references/verification.md](references/verification.md). |
| 23 | |
| 24 | Node: |
| 25 | |
| 26 | ```javascript |
| 27 | const crypto = require('crypto'); |
| 28 | |
| 29 | function verifyJiraWebhook(rawBody, signatureHeader, secret) { |
| 30 | const [method, sig] = (signatureHeader || '').split('='); |
| 31 | if (method !== 'sha256' || !sig) return false; |
| 32 | const expected = crypto.createHmac('sha256', secret).update(rawBody).digest('hex'); |
| 33 | try { |
| 34 | return crypto.timingSafeEqual(Buffer.from(sig, 'hex'), Buffer.from(expected, 'hex')); |
| 35 | } catch { |
| 36 | return false; // length mismatch = invalid |
| 37 | } |
| 38 | } |
| 39 | ``` |
| 40 | |
| 41 | Python: |
| 42 | |
| 43 | ```python |
| 44 | import hmac, hashlib |
| 45 | |
| 46 | def verify_jira_webhook(raw_body: bytes, signature_header: str, secret: str) -> bool: |
| 47 | method, _, sig = (signature_header or "").partition("=") |
| 48 | if method != "sha256" or not sig: |
| 49 | return False |
| 50 | expected = hmac.new(secret.encode(), raw_body, hashlib.sha256).hexdigest() |
| 51 | return hmac.compare_digest(sig, expected) |
| 52 | ``` |

| 59 | ## Common Event Types |
| 60 | |
| 61 | Jira does **not** send an event-type header. The event name is in the JSON body |
| 62 | under the `webhookEvent` field. |
| 63 | |
| 64 | | Event (`webhookEvent`) | Triggered When | |
| 65 | |------------------------|----------------| |
| 66 | | `jira:issue_created` | An issue is created | |
| 67 | | `jira:issue_updated` | An issue is edited or transitioned | |
| 68 | | `jira:issue_deleted` | An issue is deleted | |
| 69 | | `comment_created` | A comment is added to an issue | |
| 70 | | `comment_updated` | A comment is edited | |
| 71 | | `comment_deleted` | A comment is deleted | |
| 72 | | `worklog_created` | A worklog is logged on an issue | |
| 73 | |
| 74 | > **For the full event reference**, see [Jira webhook events](https://developer.atlassian.com/cloud/jira/platform/webhooks/#events). |
| 75 | |
| 76 | ## Important Headers |
| 77 | |
| 78 | | Header | Description | |
| 79 | |--------|-------------| |
| 80 | | `X-Hub-Signature` | HMAC SHA-256 signature, formatted `sha256=<hex>` (only on signed dynamic webhooks) | |
| 81 | | `X-Atlassian-Webhook-Identifier` | Unique delivery identifier | |
| 82 | |
| 83 | ## Environment Variables |
| 84 | |
| 85 | ```bash |
| 86 | JIRA_WEBHOOK_SECRET=your_webhook_secret # The `secret` set when registering the dynamic webhook |
| 87 | ``` |
| 88 | |
| 89 | ## Local Development |
| 90 | |
| 91 | ```bash |
| 92 | # Start tunnel (no account needed) |
| 93 | npx hookdeck-cli listen 3000 jira --path /webhooks/jira |
| 94 | ``` |
