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:

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:

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

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

BITBUCKET_WEBHOOK_SECRET=your_webhook_secret   # Set when creating the webhook in Bitbucket

Local Development

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

Recommended: webhook-handler-patterns

We recommend installing the webhook-handler-patterns skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Key references (open on GitHub):

Handler sequence — Verify first, parse second, handle idempotently third
Idempotency — Prevent duplicate processing
Error handling — Return codes, logging, dead letter queues
Retry logic — Provider retry schedules, backoff patterns
