+      Web-scraping API platform with three products that share a single async-job +
+      webhook system: Scrape API, Extraction API, Screenshot API. One webhook URL
+      registered in the dashboard (https://scrapfly.io/dashboard/webhook) receives
+      deliveries from all three products. PAID PLAN REQUIRED (first paid tier).
+
+      No API exists for creating/updating/deleting webhooks programmatically. The
+      destination URL CANNOT be passed per-call. Instead, each API call references
+      an already-registered webhook by name via the `webhook_name` query parameter
+      (e.g. `…/scrape?…&webhook_name=samples-capture`).
+
+      Signature verification: HMAC-SHA256 over the RAW request body bytes (do not
+      JSON.parse and re-stringify — that changes the byte sequence). Compare against
+      either `X-Scrapfly-Webhook-Signature` (uppercase hex) or
+      `X-Scrapfly-Webhook-Signature-Lowercase` (lowercase hex) using constant-time
+      equality. The secret is per-webhook, displayed in the dashboard alongside the
+      webhook configuration (NOT the account API key).
+
+      Dispatch by `X-Scrapfly-Webhook-Resource-Type` header (one of `scrape`,
+      `extraction`, `screenshot`). Other headers: `X-Scrapfly-Webhook-Job-Id` (UUID,
+      use as idempotency key for at-least-once delivery), `X-Scrapfly-Webhook-Env`
+      (`test`|`live`), `X-Scrapfly-Webhook-Project`, `X-Scrapfly-Webhook-Name`,
+      `X-Scrapfly-Webhook-Id`, optional `X-Scrapfly-Log-Uuid`/`X-Scrapfly-Log-Url`.
+
+      No timestamp/replay envelope (unlike Stripe). Recommend idempotency by job-id;
+      do NOT invent a `t=…` window.
+
+      Payload = the full response body of the corresponding API plus a `context`
+      overlay: `context.webhook` (`{ name, secret, consecutive_failed_count, … }` —
+      WARN handlers: `secret` field exposes the signing secret in the payload, do
+      not log or echo) and `context.job` (`{ uuid, … }`). Product-specific shapes
+      documented in the getting-started pages above.
+
+      Delivery: retry 30s → 1min → 5min → 30min → 1h → 1d. A webhook is DISABLED
+      after 100 consecutive failures — handlers should return 2xx fast and surface
+      errors out-of-band.
+
+      No official SDK construct for verification (plain HMAC is correct). Do NOT
+      pull in a third-party HMAC library; use the stdlib (`crypto.createHmac` in
+      Node, `hmac` / `hashlib` in Python).

+# Scrapfly Webhooks
+
+## When to Use This Skill
+
+- How do I receive Scrapfly webhooks?
+- How do I verify Scrapfly webhook signatures?
+- How do I handle async Scrape API, Extraction API, or Screenshot API results?
+- How do I route Scrapfly webhooks by resource type (scrape, extraction, screenshot)?
+- How do I handle Crawler API webhook events (`crawler_started`, `crawler_finished`, ...)?
+- Why is my Scrapfly webhook signature verification failing?
+
+## How Scrapfly Webhooks Work
+
+Scrapfly uses HMAC-SHA256 with **uppercase hex** encoding over the **raw request body**. There is no SDK for webhook verification — implementations follow Scrapfly's documented algorithm.
+
+Key facts:
+
+- **Signature header**: `X-Scrapfly-Webhook-Signature` (uppercase hex). A duplicate `X-Scrapfly-Webhook-Signature-Lowercase` is also sent for runtimes that normalise headers.
+- **Algorithm**: `HMAC-SHA256(secret, raw_body).hexdigest().upper()`
+- **What is signed**: The **raw request body bytes**. Do **not** parse and re-serialise JSON — that changes the byte sequence and breaks the signature.
+- **No timestamp / replay window**: Scrapfly does not include a timestamp header; treat the signature as authenticity-only.
+- **Secret**: Use the value from the Scrapfly dashboard exactly as shown. Do not trim or base64-decode it.
+- **Routing**: Use `X-Scrapfly-Webhook-Resource-Type` (`scrape`, `extraction`, `screenshot`) to dispatch when one endpoint serves multiple products. Crawler events also carry `X-Scrapfly-Crawl-Event-Name` and an `event` field in the body.
+
+## Essential Code (USE THIS)
+
+### Scrapfly Signature Verification (JavaScript)
+
+```javascript
+const crypto = require('crypto');
+
+function verifyScrapflySignature(rawBody, signatureHeader, secret) {
+  if (!signatureHeader || !secret) return false;
+
+  // Scrapfly emits uppercase hex
+  const expected = crypto
+    .createHmac('sha256', secret)
+    .update(rawBody)
+    .digest('hex')
+    .toUpperCase();
+
+  // Accept either casing — Scrapfly also sends an X-...-Lowercase variant
+  const received = signatureHeader.toUpperCase();
+
+  try {
+    return crypto.timingSafeEqual(
+      Buffer.from(received, 'hex'),
+      Buffer.from(expected, 'hex')
+    );
+  } catch {
+    return false;
+  }
+}
+```
+
+### Express Webhook Handler
+
+```javascript
+const express = require('express');
+const app = express();
+
+// CRITICAL: Use express.raw() — Scrapfly signs the raw body bytes
+app.post('/webhooks/scrapfly',
+  express.raw({ type: '*/*' }),
+  (req, res) => {
+    const signature = req.headers['x-scrapfly-webhook-signature'];
+    const resourceType = req.headers['x-scrapfly-webhook-resource-type'];
+    const jobId = req.headers['x-scrapfly-webhook-job-id'];
+    const webhookId = req.headers['x-scrapfly-webhook-id'];
+
+    if (!verifyScrapflySignature(req.body, signature, process.env.SCRAPFLY_WEBHOOK_SECRET)) {
+      console.error('Scrapfly signature verification failed');
+      return res.status(401).send('Invalid signature');
+    }
+
+    // Parse only after verifying
+    const payload = JSON.parse(req.body.toString());
+
+    console.log(`Scrapfly ${resourceType} webhook (job ${jobId}, id ${webhookId})`);
+
+    // Route by resource type for scrape / extraction / screenshot APIs
+    switch (resourceType) {
+      case 'scrape':
+        // Scrape API places the fetched URL at result.url; the webhook overlay's
+        // context only carries `webhook` and `job` sub-objects.
+        console.log('Scrape result:', payload.result?.status_code, payload.result?.url);
+        break;
+      case 'extraction':
+        console.log('Extraction result:', payload.result?.data);
+        break;
+      case 'screenshot':
+        console.log('Screenshot result:', payload.result?.screenshot_url);
+        break;
+      default:
+        // Crawler API uses event names in the body
+        if (payload.event) {
+          console.log(`Crawler event: ${payload.event}`, payload.payload);
+        } else {
+          console.log('Unhandled resource type:', resourceType);
+        }
+    }
+
+    res.status(200).send('OK');
+  }
+);
+```
+
+### Python Signature Verification (FastAPI)
+
+```python
+import hmac
+import hashlib
+
+def verify_scrapfly_signature(raw_body: bytes, signature_header: str, secret: str) -> bool:
+    if not signature_header or not secret:
+        return False
+
+    expected = hmac.new(
+        secret.encode('utf-8'),
+        raw_body,
+        hashlib.sha256,
+    ).hexdigest().upper()
+
+    # Compare case-insensitively (Scrapfly also sends a lowercase header)
+    return hmac.compare_digest(expected, signature_header.upper())
+```

+> - [examples/nextjs/](examples/nextjs/) - Next.js App Router implementation
+> - [examples/fastapi/](examples/fastapi/) - Python FastAPI implementation
+
+## Common Resource Types and Crawler Events
+
+The `X-Scrapfly-Webhook-Resource-Type` header identifies the originating API:
+
+| Resource Type | Description |
+|---------------|-------------|
+| `scrape` | Async Scrape API result delivery |
+| `extraction` | Async Extraction API result delivery |
+| `screenshot` | Async Screenshot API result delivery |
+
+Crawler API webhooks carry an `event` string in the body (also exposed as `X-Scrapfly-Crawl-Event-Name`):
+
+| Event | Description |
+|-------|-------------|
+| `crawler_started` | Crawl job began |
+| `crawler_url_visited` | A URL was successfully fetched |
+| `crawler_url_discovered` | A new URL was queued |
+| `crawler_url_skipped` | A URL was skipped (filters, dedupe, ...) |
+| `crawler_url_failed` | A URL fetch failed |
+| `crawler_stopped` | Crawl stopped (limit reached) |
+| `crawler_cancelled` | Crawl cancelled by user |
+| `crawler_finished` | Crawl finished naturally |
+
+> **For more context**, see [Scrapfly Scrape API Webhooks](https://scrapfly.io/docs/scrape-api/webhook), [Extraction API Webhooks](https://scrapfly.io/docs/extraction-api/webhook), [Screenshot API Webhooks](https://scrapfly.io/docs/screenshot-api/webhook), and [Crawler API](https://scrapfly.io/docs/crawler-api/getting-started).
+
+## Important Headers
+
+| Header | Description |
+|--------|-------------|
+| `X-Scrapfly-Webhook-Signature` | HMAC-SHA256 of the raw body, uppercase hex |
+| `X-Scrapfly-Webhook-Signature-Lowercase` | Same signature, lowercase hex |
+| `X-Scrapfly-Webhook-Id` | Unique webhook delivery identifier |
+| `X-Scrapfly-Webhook-Name` | Name of the configured webhook |
+| `X-Scrapfly-Webhook-Resource-Type` | `scrape`, `extraction`, or `screenshot` |
+| `X-Scrapfly-Webhook-Job-Id` | Unique job identifier (use for reconciliation) |
+| `X-Scrapfly-Webhook-Env` | Environment (`test` or `live`) |
+| `X-Scrapfly-Webhook-Project` | Project name |
+| `X-Scrapfly-Crawl-Event-Name` | Crawler API event name (e.g. `crawler_finished`) |
+
+## Environment Variables
+
+```bash
+SCRAPFLY_WEBHOOK_SECRET=your_signing_secret_here   # From the Scrapfly dashboard
+```
+
+## Local Development
+
+For local webhook testing, use the Hookdeck CLI tunnel (no account required, no install step needed):
+
+```bash
+# Express / Next.js (port 3000)
+npx hookdeck-cli listen 3000 scrapfly --path /webhooks/scrapfly
+
+# FastAPI (port 8000)
+npx hookdeck-cli listen 8000 scrapfly --path /webhooks/scrapfly
+```
+
+Configure the tunnel URL as the destination in your Scrapfly dashboard webhook, then trigger an async job with `webhook_name=<name>` to invoke delivery.

+# Scrapfly Webhooks - Express Example
+
+Minimal example of receiving Scrapfly webhooks with signature verification.
+
+## Prerequisites
+
+- Node.js 18+
+- A Scrapfly account with a webhook configured (see [setup.md](../../references/setup.md))
+
+## Setup
+
+1. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+2. Copy environment variables:
+   ```bash
+   cp .env.example .env
+   ```
+
+3. Add your Scrapfly webhook signing secret to `.env`:
+   ```bash
+   SCRAPFLY_WEBHOOK_SECRET=<value-from-scrapfly-dashboard>
+   ```
+
+## Run
+
+```bash
+npm start
+```
+
+Server runs on http://localhost:3000.
+
+## Test
+
+```bash
+npm test
+```
+
+The test suite generates valid HMAC-SHA256 signatures with the same algorithm Scrapfly uses (uppercase hex over the raw body) and asserts the endpoint accepts/rejects accordingly.
+
+## Receive Webhooks Locally
+
+Use the Hookdeck CLI tunnel (no install step required):
+
+```bash
+npx hookdeck-cli listen 3000 scrapfly --path /webhooks/scrapfly
+```
+
+Paste the printed public URL into your Scrapfly dashboard webhook configuration, then trigger an async Scrapfly job with `webhook_name=<your-webhook-name>&async=true`.
+
+## Endpoint
+
+- `POST /webhooks/scrapfly` — Receives and verifies Scrapfly webhook deliveries
+- `GET /health` — Health check
+
+## How It Works
+
+1. The webhook body arrives as raw bytes (`express.raw({ type: '*/*' })`).
+2. `verifyScrapflySignature` computes `upper(hex(HMAC_SHA256(secret, rawBody)))` and timing-safe-compares it to the `X-Scrapfly-Webhook-Signature` header.
+3. If valid, the body is `JSON.parse`d and dispatched by `X-Scrapfly-Webhook-Resource-Type` (`scrape` / `extraction` / `screenshot`) or, for the Crawler API, by the `event` field in the body.

+# Scrapfly Webhooks - FastAPI Example
+
+Minimal FastAPI example of receiving Scrapfly webhooks with signature verification.
+
+## Prerequisites
+
+- Python 3.9+
+- A Scrapfly account with a webhook configured (see [setup.md](../../references/setup.md))
+
+## Setup
+
+1. Create a virtual environment and install dependencies:
+   ```bash
+   python3 -m venv venv
+   source venv/bin/activate
+   pip install -r requirements.txt
+   ```
+
+2. Copy environment variables:
+   ```bash
+   cp .env.example .env
+   ```
+
+3. Add your Scrapfly webhook signing secret to `.env`:
+   ```bash
+   SCRAPFLY_WEBHOOK_SECRET=<value-from-scrapfly-dashboard>
+   ```
+
+## Run
+
+```bash
+uvicorn main:app --reload --port 8000
+```
+
+Server runs on http://localhost:8000.
+
+## Test
+
+```bash
+pytest test_webhook.py -v
+```
+
+The tests generate valid Scrapfly signatures (`upper(hex(HMAC_SHA256(secret, body)))`) — the same algorithm Scrapfly's docs document — and assert the endpoint accepts/rejects accordingly.
+
+## Receive Webhooks Locally
+
+```bash
+npx hookdeck-cli listen 8000 scrapfly --path /webhooks/scrapfly
+```
+
+Paste the printed public URL into your Scrapfly dashboard webhook configuration.
+
+## Endpoint
+
+- `POST /webhooks/scrapfly` — Receives and verifies Scrapfly webhook deliveries
+- `GET /health` — Health check
+
+## How It Works
+
+The handler reads the raw bytes with `await request.body()`, computes `hmac.new(secret, body, sha256).hexdigest().upper()`, and constant-time-compares it to `X-Scrapfly-Webhook-Signature` (uppercased). Only after verification does it `json.loads` the payload and route by `X-Scrapfly-Webhook-Resource-Type` (`scrape` / `extraction` / `screenshot`) or by the Crawler `event` field.

+# Scrapfly Webhooks - Next.js Example
+
+Minimal Next.js App Router example of receiving Scrapfly webhooks with signature verification.
+
+## Prerequisites
+
+- Node.js 18+
+- A Scrapfly account with a webhook configured (see [setup.md](../../references/setup.md))
+
+## Setup
+
+1. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+2. Copy environment variables:
+   ```bash
+   cp .env.example .env
+   ```
+
+3. Add your Scrapfly webhook signing secret to `.env`:
+   ```bash
+   SCRAPFLY_WEBHOOK_SECRET=<value-from-scrapfly-dashboard>
+   ```
+
+## Run
+
+```bash
+npm run dev
+```
+
+Server runs on http://localhost:3000.
+
+## Test
+
+```bash
+npm test
+```
+
+The test suite generates valid Scrapfly signatures (`upper(hex(HMAC_SHA256(secret, body)))`) and asserts the route accepts/rejects accordingly.
+
+## Receive Webhooks Locally
+
+```bash
+npx hookdeck-cli listen 3000 scrapfly --path /webhooks/scrapfly
+```
+
+Paste the printed public URL into the Scrapfly dashboard webhook configuration.
+
+## Endpoint
+
+- `POST /webhooks/scrapfly` — `app/webhooks/scrapfly/route.ts`
+
+## How It Works
+
+The route reads the request as raw text with `await request.text()` (so the bytes are exactly what Scrapfly signed), verifies `X-Scrapfly-Webhook-Signature` with `crypto.timingSafeEqual`, and only then `JSON.parse`s the payload and routes by `X-Scrapfly-Webhook-Resource-Type` or the body's `event` field for Crawler events.

+# Scrapfly Webhooks Overview
+
+## What Are Scrapfly Webhooks?
+
+Scrapfly is a web scraping API. When you submit a long-running job (async scrape, extraction, screenshot, or a Crawler run), Scrapfly delivers the result to a webhook endpoint you configure in the dashboard.
+
+A webhook is identified by a **name** in the dashboard. You attach it to a request by passing `webhook_name=<name>` on the Scrape / Extraction / Screenshot API call, or by configuring it on the Crawler job. Scrapfly then POSTs the result (or, for the Crawler, lifecycle events) to your endpoint.
+
+## Resource Types
+
+The `X-Scrapfly-Webhook-Resource-Type` header tells you which product the delivery came from. Use it to dispatch when one endpoint handles multiple Scrapfly products:
+
+| Resource Type | Triggered When | Common Use Cases |
+|---------------|----------------|------------------|
+| `scrape` | An async Scrape API job finishes | Save HTML / extracted fields, kick off downstream parsing |
+| `extraction` | An async Extraction API job finishes | Persist structured data, enqueue follow-up enrichment |
+| `screenshot` | An async Screenshot API job finishes | Store image URL, notify users, generate thumbnails |
+
+The body of a `scrape` / `extraction` / `screenshot` webhook is the full JSON response of the corresponding synchronous API call with a `context` overlay added:
+
+```json
+{
+  "...api_response": "...",
+  "context": {
+    "...api_context": "...",
+    "webhook": {
+      "name": "my-webhook",
+      "secret": "<signing secret — DO NOT log>",
+      "consecutive_failed_count": 0
+    },
+    "job": {
+      "uuid": "550e8400-e29b-41d4-a716-446655440000"
+    }
+  }
+}
+```
+
+The webhook overlay always carries:
+
+- `context.webhook.name` — webhook name configured in the dashboard
+- `context.webhook.secret` — the signing secret (**never log or echo this field**)
+- `context.webhook.consecutive_failed_count` — current consecutive-failure count
+- `context.job.uuid` — job UUID (same value as `X-Scrapfly-Webhook-Job-Id`)
+
+Product-specific fields (such as `result.content`, `result.data`, `result.screenshot_url`, or the API's own `context.url`) come from the underlying API response — see the [Scrape](https://scrapfly.io/docs/scrape-api/getting-started), [Extraction](https://scrapfly.io/docs/extraction-api/getting-started), and [Screenshot](https://scrapfly.io/docs/screenshot-api/getting-started) getting-started pages for shapes.
+
+## Crawler Events
+
+The Crawler API is a separate product that delivers **lifecycle events** rather than a single result. Each event has an `event` field in the body (and an `X-Scrapfly-Crawl-Event-Name` header):
+
+| Event | Default? | Triggered When |
+|-------|----------|----------------|
+| `crawler_started` | Yes | Crawl job started |
+| `crawler_stopped` | Yes | The crawl stopped (budget/limit reached) |
+| `crawler_cancelled` | Yes | The crawl was cancelled |
+| `crawler_finished` | Yes | The crawl ran to completion |
+| `crawler_url_visited` | Opt-in | A URL was fetched successfully |
+| `crawler_url_discovered` | Opt-in | A new URL was added to the queue |
+| `crawler_url_skipped` | Opt-in | A URL was skipped (deduped, filtered) |
+| `crawler_url_failed` | Opt-in | A URL fetch failed |
+
+By default Scrapfly only delivers the four lifecycle events: `crawler_started`, `crawler_stopped`, `crawler_cancelled`, `crawler_finished`. The per-URL events (`crawler_url_visited`, `crawler_url_discovered`, `crawler_url_skipped`, `crawler_url_failed`) are high-volume and must be enabled explicitly via the `webhook_events` parameter when submitting the crawl job.
+
+Example Crawler payload:
+
+```json
+{
+  "event": "crawler_url_visited",
+  "payload": {
+    "crawler_uuid": "550e8400-e29b-41d4-a716-446655440000",
+    "url": "https://web-scraping.dev/page",
+    "status_code": 200,
+    "depth": 1,
+    "state": {
+      "urls_visited": 42,
+      "urls_to_crawl": 158,
+      "api_credit_used": 420
+    }
+  }
+}
+```
+
+## Common Headers
+
+| Header | Description |
+|--------|-------------|
+| `X-Scrapfly-Webhook-Signature` | HMAC-SHA256 of the raw body, **uppercase hex** |
+| `X-Scrapfly-Webhook-Signature-Lowercase` | Same signature in lowercase hex |
+| `X-Scrapfly-Webhook-Id` | Unique webhook delivery ID — use for idempotency |
+| `X-Scrapfly-Webhook-Name` | Name of the webhook configured in the dashboard |
+| `X-Scrapfly-Webhook-Resource-Type` | `scrape`, `extraction`, or `screenshot` |
+| `X-Scrapfly-Webhook-Job-Id` | Job UUID returned at enqueue time — reconciliation key |
+| `X-Scrapfly-Webhook-Env` | Environment label (`test` or `live`) |
+| `X-Scrapfly-Webhook-Project` | Project name |
+| `X-Scrapfly-Crawl-Event-Name` | Crawler API event name (e.g. `crawler_finished`) |
+| `X-Scrapfly-Log-Uuid` / `X-Scrapfly-Log-Url` | Pointers to the Scrapfly log entry for the delivery |
+
+## Delivery & Retries
+
+Scrapfly delivery is **at-least-once**. Use `X-Scrapfly-Webhook-Job-Id` as your idempotency key — duplicates carry the same job UUID.
+
+Retry schedule on non-2xx responses (or timeout):
+
+| Attempt | Delay after previous |
+|---------|----------------------|
+| 1 | initial delivery |
+| 2 | 30 s |
+| 3 | 1 min |
+| 4 | 5 min |
+| 5 | 30 min |
+| 6 | 1 h |
+| 7 | 1 d |
+
+After **100 consecutive failures** Scrapfly automatically **disables** the webhook — no further deliveries are attempted until you re-enable it in the dashboard. Because of this, handlers should:
+
+- Return 2xx as soon as the signature is verified and the job is enqueued.
+- Surface processing errors out-of-band (logs, alerts, dead-letter queue) rather than 5xx-ing back to Scrapfly.

+# Setting Up Scrapfly Webhooks
+
+## Prerequisites
+
+- A Scrapfly account ([sign up](https://scrapfly.io))
+- A **paid Scrapfly plan**. Webhooks are not available on the FREE plan — its webhook queue size is 0, so no deliveries are ever dispatched even after configuration. Any paid tier enables delivery.
+- A publicly reachable webhook endpoint URL (use [Hookdeck CLI](https://hookdeck.com/docs/cli) for local development)
+
+## Create a Webhook in the Scrapfly Dashboard
+
+1. Sign in to your Scrapfly dashboard at [scrapfly.io](https://scrapfly.io).
+2. Go to **Webhooks** in the navigation.
+3. Click **Create Webhook**.
+4. Fill in:
+   - **Name** — A short identifier. You will pass this as `webhook_name=<name>` on API calls. Names are scoped per project + environment.
+   - **URL** — Your endpoint, e.g. `https://your-app.example.com/webhooks/scrapfly`.
+   - (Optional) Environment / project scoping.
+5. Save the webhook. Scrapfly will display a **signing secret** — copy it. The dashboard is the only place this secret is shown.
+
+## Configure the Signing Secret in Your App
+
+Add the secret to your `.env`:
+
+```bash
+SCRAPFLY_WEBHOOK_SECRET=<value-from-dashboard>
+```
+
+Use it **exactly as shown** in the dashboard. Do not trim, base64-decode, or otherwise transform it — Scrapfly treats it as a raw UTF-8 string.
+
+## Trigger a Delivery
+
+### Scrape / Extraction / Screenshot APIs
+
+Pass `webhook_name` on the API call. Example for the Scrape API:
+
+```bash
+curl "https://api.scrapfly.io/scrape?key=$SCRAPFLY_KEY&url=https://web-scraping.dev/products&webhook_name=my-webhook&async=true"
+```
+
+The call returns immediately with a `job_uuid`. When the job finishes, Scrapfly POSTs the result to your endpoint with:
+
+- `X-Scrapfly-Webhook-Resource-Type: scrape`
+- `X-Scrapfly-Webhook-Job-Id: <job_uuid>`
+- `X-Scrapfly-Webhook-Signature: <UPPERCASE_HEX_HMAC_SHA256>`
+
+The same pattern works for `https://api.scrapfly.io/extraction` (resource type `extraction`) and `https://api.scrapfly.io/screenshot` (resource type `screenshot`).
+
+### Crawler API
+
+Attach a webhook to a Crawler job when you submit it. Scrapfly will POST lifecycle events (`crawler_started`, `crawler_url_visited`, ..., `crawler_finished`) to your endpoint. The event name is also in the body's `event` field and in `X-Scrapfly-Crawl-Event-Name`.
+
+## Verify Locally with Hookdeck CLI
+
+No account or install needed:
+
+```bash
+# Forward incoming webhooks to your local server
+npx hookdeck-cli listen 3000 scrapfly --path /webhooks/scrapfly
+```
+
+The CLI prints a public URL — paste that into the **URL** field when creating the webhook in the Scrapfly dashboard. Trigger a job with `async=true&webhook_name=<name>` and watch the request appear in the Hookdeck UI.
+
+## Environments
+
+Scrapfly webhooks are scoped per **project** and **environment**. The delivery includes `X-Scrapfly-Webhook-Env` and `X-Scrapfly-Webhook-Project` headers so you can keep one endpoint for multiple environments.

+# Scrapfly Signature Verification
+
+## How It Works
+
+Scrapfly signs every webhook with **HMAC-SHA256** over the **raw request body bytes**. The digest is emitted as **uppercase hexadecimal** in the `X-Scrapfly-Webhook-Signature` header. A duplicate lowercase variant is sent as `X-Scrapfly-Webhook-Signature-Lowercase` for runtimes that normalise headers.
+
+There is **no timestamp** in the scheme and **no replay window** — treat the signature as authenticity-only. (If you need replay protection, gate processing on the `X-Scrapfly-Webhook-Id` header or the job UUID.)
+
+## Algorithm
+
+```
+signature = upper(hex(HMAC_SHA256(secret_utf8, raw_body_bytes)))
+```
+
+Compare with `received == signature` using a constant-time comparison.
+
+## Implementation
+
+Scrapfly does not publish an SDK for webhook verification — implementations follow the documented algorithm manually.
+
+### Node.js / Express / Next.js
+
+```javascript
+const crypto = require('crypto');
+
+function verifyScrapflySignature(rawBody, signatureHeader, secret) {
+  if (!signatureHeader || !secret) return false;
+
+  const expected = crypto
+    .createHmac('sha256', secret)
+    .update(rawBody)
+    .digest('hex')
+    .toUpperCase();
+
+  const received = signatureHeader.toUpperCase();
+
+  try {
+    return crypto.timingSafeEqual(
+      Buffer.from(received, 'hex'),
+      Buffer.from(expected, 'hex')
+    );
+  } catch {
+    return false;
+  }
+}
+```
+
+Notes:
+- `rawBody` must be a `Buffer` (Express) or the raw `string` from `await request.text()` (Next.js). **Never** `JSON.parse` and re-stringify — that mutates whitespace/key order and breaks the signature.
+- `crypto.timingSafeEqual` requires equal-length buffers; the `try/catch` swallows length mismatches so the function returns `false` rather than throwing.
+
+### Python / FastAPI
+
+```python
+import hmac
+import hashlib
+
+def verify_scrapfly_signature(raw_body: bytes, signature_header: str, secret: str) -> bool:
+    if not signature_header or not secret:
+        return False
+
+    expected = hmac.new(
+        secret.encode('utf-8'),
+        raw_body,
+        hashlib.sha256,
+    ).hexdigest().upper()
+
+    return hmac.compare_digest(expected, signature_header.upper())
+```
+
+Notes:
+- Use `await request.body()` in FastAPI to get `bytes`. Do not call `await request.json()` before verifying.
+- `hmac.compare_digest` is the documented constant-time comparator.
+
+## Security: Do Not Log the Raw Payload
+
+Scrapfly echoes the webhook signing secret in the body at `context.webhook.secret`. This is unusual compared to other providers and easy to miss.
+
+- **Never** log the raw payload, dump it to stdout in production, or forward it to third-party tools (Sentry, Datadog, Slack, etc.) without redacting `context.webhook.secret` first.
+- If you persist webhooks for replay/debugging, strip or redact `context.webhook.secret` before storage.
+- Anyone with the secret can forge valid signatures for your endpoint.
+
+```javascript
+// Redact before logging / forwarding
+const safe = { ...payload, context: { ...payload.context, webhook: { ...payload.context?.webhook, secret: '[REDACTED]' } } };
+```
+
+## Common Gotchas
+
+- **Parsed JSON breaks signatures.** Verify against the exact bytes Scrapfly sent. In Express, mount `express.raw({ type: '*/*' })` on the webhook route (not `express.json`). In Next.js App Router, read with `await request.text()`. In FastAPI, use `await request.body()`.
+- **Case of the hex digest.** Scrapfly's primary header is uppercase, but the `-Lowercase` variant exists for a reason. Always normalise both sides before comparing (the snippets above use `.toUpperCase()` / `.upper()`).
+- **Header casing in HTTP frameworks.** HTTP header names are case-insensitive. Express lowercases everything; Next.js's `headers.get(...)` is also case-insensitive. Read `x-scrapfly-webhook-signature`.
+- **No timestamp tolerance.** Don't reject for old timestamps — there isn't one. If you need replay protection, dedupe on `X-Scrapfly-Webhook-Id`.
+- **Secret format.** Use the dashboard string verbatim. There is no `whsec_` prefix to strip and no base64 decode step.
+- **Body encoding.** The HMAC is over bytes, not text. Avoid any middleware that transforms encoding (gzip middleware, BOM strippers, etc.) on the route.
+
+## Debugging Verification Failures
+
+1. **Log both signatures side-by-side** (the computed expected and the received header) — they should be identical, byte for byte, after normalising case.
+2. **Log the body length** received vs. the `Content-Length` header. A mismatch means a middleware ate the body.
+3. **Hash a known string with your secret** locally and compare with Scrapfly's documented Python sample:
+   ```python
+   hmac.new(b'YOUR-SECRET', b'{"data": "example"}', hashlib.sha256).hexdigest().upper()
+   ```
+4. **Check the right header.** `X-Scrapfly-Webhook-Signature` (uppercase hex) — not `Signature`, not `X-Signature`, not `webhook-signature`.
+5. **Confirm you're using the right secret.** Webhooks are scoped per project + environment; the dashboard shows the secret for the specific webhook.
