# Bitbucket Webhooks

## When to Use This Skill

- Setting up Bitbucket Cloud webhook handlers - Debugging Bitbucket signature verification failures - Understanding Bitbucket event keys and payloads - Handling repo:push, pull request, or issue events

## Verification (core)

Bitbucket signs the **raw** request body with HMAC-SHA256 keyed on your webhook secret and sends the digest in the `X-Hub-Signature` header formatted as `sha256=<hex>` (the prefix names the algorithm — currently `sha256`). Pass the raw body, and compare timing-safe. Webhooks configured **without** a secret are unsigned and send no `X-Hub-Signature` header.

Node:

```javascript const crypto = require('crypto');

function verify(rawBody, signatureHeader, secret) { const [algo, sig] = (signatureHeader || '').split('='); if (algo !== 'sha256' || !sig) return false; const expected = crypto.createHmac('sha256', secret).update(rawBody).digest('hex'); try { return crypto.timingSafeEqual(Buffer.from(sig), Buffer.from(expected)); } catch { return false; } } ```

Python:

```python import hmac, hashlib

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

## Common Event Types

| Event Key | Description | |-----------|-------------| | `repo:push` | Commits pushed to a branch or tag | | `pullrequest:created` | Pull request opened | | `pullrequest:updated` | Pull request title/description/commits updated | | `pullrequest:approved` | Pull request approved by a reviewer | | `pullrequest:fulfilled` | Pull request merged | | `pullrequest:rejected` | Pull request declined | | `pullrequest:comment_created` | Comment added to a pull request | | `issue:created` | Issue created |

> **For full event reference**, see [Bitbucket Event Payloads](https://support.atlassian.com/bitbucket-cloud/docs/event-payloads/)

## Important Headers

| Header | Description | |--------|-------------| | `X-Hub-Signature` | HMAC SHA-256 signature as `sha256=<hex>` (only when a secret is set) | | `X-Event-Key` | Event type (e.g. `repo:push`, `pullrequest:created`) | | `X-Request-UUID` | Unique delivery ID | | `X-Attempt-Number` | Retry attempt number for this delivery |

## Environment Variables

```bash BITBUCKET_WEBHOOK_SECRET=your_webhook_secret # Set when creating the webhook in Bitbucket ```

## Local Development

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