| 3 | ## When to Use This Skill |
| 4 | |
| 5 | - Setting up Bitbucket Cloud webhook handlers |
| 6 | - Debugging Bitbucket signature verification failures |
| 7 | - Understanding Bitbucket event keys and payloads |
| 8 | - Handling repo:push, pull request, or issue events |
| 9 | |
| 10 | ## Verification (core) |
| 11 | |
| 12 | Bitbucket signs the **raw** request body with HMAC-SHA256 keyed on your webhook |
| 13 | secret and sends the digest in the `X-Hub-Signature` header formatted as |
| 14 | `sha256=<hex>` (the prefix names the algorithm — currently `sha256`). Pass the |
| 15 | raw body, and compare timing-safe. Webhooks configured **without** a secret are |
| 16 | unsigned and send no `X-Hub-Signature` header. |
| 17 | |
| 18 | Node: |
| 19 | |
| 20 | ```javascript |
| 21 | const crypto = require('crypto'); |
| 22 | |
| 23 | function verify(rawBody, signatureHeader, secret) { |
| 24 | const [algo, sig] = (signatureHeader || '').split('='); |
| 25 | if (algo !== 'sha256' || !sig) return false; |
| 26 | const expected = crypto.createHmac('sha256', secret).update(rawBody).digest('hex'); |
| 27 | try { |
| 28 | return crypto.timingSafeEqual(Buffer.from(sig), Buffer.from(expected)); |
| 29 | } catch { |
| 30 | return false; |
| 31 | } |
| 32 | } |
| 33 | ``` |
| 34 | |
| 35 | Python: |
| 36 | |
| 37 | ```python |
| 38 | import hmac, hashlib |
| 39 | |
| 40 | def verify(raw_body: bytes, signature_header: str, secret: str) -> bool: |
| 41 | algo, _, sig = (signature_header or "").partition("=") |
| 42 | if algo != "sha256" or not sig: |
| 43 | return False |
| 44 | expected = hmac.new(secret.encode(), raw_body, hashlib.sha256).hexdigest() |
| 45 | return hmac.compare_digest(sig, expected) |
| 46 | ``` |

| 53 | ## Common Event Types |
| 54 | |
| 55 | | Event Key | Description | |
| 56 | |-----------|-------------| |
| 57 | | `repo:push` | Commits pushed to a branch or tag | |
| 58 | | `pullrequest:created` | Pull request opened | |
| 59 | | `pullrequest:updated` | Pull request title/description/commits updated | |
| 60 | | `pullrequest:approved` | Pull request approved by a reviewer | |
| 61 | | `pullrequest:fulfilled` | Pull request merged | |
| 62 | | `pullrequest:rejected` | Pull request declined | |
| 63 | | `pullrequest:comment_created` | Comment added to a pull request | |
| 64 | | `issue:created` | Issue created | |
| 65 | |
| 66 | > **For full event reference**, see [Bitbucket Event Payloads](https://support.atlassian.com/bitbucket-cloud/docs/event-payloads/) |
| 67 | |
| 68 | ## Important Headers |
| 69 | |
| 70 | | Header | Description | |
| 71 | |--------|-------------| |
| 72 | | `X-Hub-Signature` | HMAC SHA-256 signature as `sha256=<hex>` (only when a secret is set) | |
| 73 | | `X-Event-Key` | Event type (e.g. `repo:push`, `pullrequest:created`) | |
| 74 | | `X-Request-UUID` | Unique delivery ID | |
| 75 | | `X-Attempt-Number` | Retry attempt number for this delivery | |
| 76 | |
| 77 | ## Environment Variables |
| 78 | |
| 79 | ```bash |
| 80 | BITBUCKET_WEBHOOK_SECRET=your_webhook_secret # Set when creating the webhook in Bitbucket |
| 81 | ``` |
| 82 | |
| 83 | ## Local Development |
| 84 | |
| 85 | ```bash |
| 86 | # Start tunnel (no account needed) |
| 87 | npx hookdeck-cli listen 3000 bitbucket --path /webhooks/bitbucket |
| 88 | ``` |
