+### Error Reporting System (Vercel Serverless) (`api/report-error.ts`, `src/util/notifications/ErrorReportingWebhook.ts`)
+
+**MAJOR REDESIGN (2025-01-02):** Complete rewrite from Discord webhooks → Vercel Serverless Functions
+
+**OLD SYSTEM (Pre-2025) - DEPRECATED:**
+- ❌ Hardcoded Discord webhooks (4 redundancy URLs in base64)
+- ❌ AES-256-GCM obfuscation with `ERROR_WEBHOOK_KEY`
+- ❌ Webhook rotation logic (`disabled-webhooks.json` tracking)
+- ❌ Users could disable webhooks (config control)
+- ❌ ~600 lines of complex code
+- ❌ Disabled since 2024-12-26 due to vulnerabilities
+
+**NEW SYSTEM (2025+) - ACTIVE:**
+- ✅ Vercel Serverless Function: `api/report-error.ts`
+- ✅ Webhook URL in Vercel environment variables (NEVER in code)
+- ✅ Server-side rate limiting (10 req/min/IP, bypass with `X-Rate-Limit-Secret`)
+- ✅ ~300 lines of clean code (50% reduction)
+- ✅ Free Vercel tier (100,000 requests/day)
+- ✅ Maintainer-controlled (users can opt-out but not break system)
+
+**Architecture:**
+```
+Bot → POST /api/report-error → Vercel Function → Discord Webhook
+         (sanitized payload)    (env vars)         (maintainer's server)
+```
+
+**Key Features:**
+- **Sanitization:** Redacts emails, paths, IPs, tokens (SANITIZE_PATTERNS)
+- **Filtering:** Skips user config errors, expected errors (shouldReportError)
+- **Payload:** Error message, stack trace (15 lines), version, platform, botMode
+- **Config:** `errorReporting.enabled`, `apiUrl`, `secret` (optional bypass)
+
+**Files:**
+- `api/report-error.ts` - Vercel serverless function (TypeScript)
+- `vercel.json` - Vercel deployment config
+- `api/README.md` - Setup instructions for maintainers
+- `docs/error-reporting-vercel.md` - Full documentation
+- `src/interface/Config.ts` - `ConfigErrorReporting` interface
+
+**Setup (Maintainers):**
+1. Add `DISCORD_ERROR_WEBHOOK_URL` to Vercel env vars
+2. Optional: Add `RATE_LIMIT_SECRET` for trusted clients
+3. Deploy: `git push` or `vercel --prod`
+4. Test: `curl -X POST https://rewards-bot-eight.vercel.app/api/report-error`
+
+**Migration Guide:**
+- Old `errorReporting.webhooks[]` config field DEPRECATED (still supported as fallback)
+- Old `sessions/disabled-webhooks.json` file NO LONGER USED
+- Bot automatically uses new API (no user action required)

+# Vercel Error Reporting Configuration
+
+This directory contains Vercel Serverless Functions for centralized error reporting.
+
+## Setup Instructions
+
+### 1. Configure Discord Webhook in Vercel
+
+1. Go to your Vercel project: https://vercel.com/lightzirconites-projects/rewards-bot
+2. Navigate to **Settings** → **Environment Variables**
+3. Add the following variable:
+   - **Name:** `DISCORD_ERROR_WEBHOOK_URL`
+   - **Value:** Your Discord webhook URL (e.g., `https://discord.com/api/webhooks/...`)
+   - **Environment:** Production, Preview, Development (select all)
+
+### 2. Optional: Configure Rate Limit Secret (for trusted clients)
+
+To bypass rate limits for trusted bot instances:
+
+1. Add another environment variable:
+   - **Name:** `RATE_LIMIT_SECRET`
+   - **Value:** A secure random string (e.g., `openssl rand -base64 32`)
+   - **Environment:** Production, Preview, Development
+
+2. In the bot's `config.jsonc`, add:
+   ```jsonc
+   {
+     "errorReporting": {
+       "enabled": true,
+       "apiUrl": "https://rewards-bot-eight.vercel.app/api/report-error",
+       "secret": "your-secret-here"  // Same as RATE_LIMIT_SECRET
+     }
+   }
+   ```
+
+### 3. Deploy to Vercel
+
+After configuring environment variables:
+
+```bash
+# Option 1: Git push (automatic deployment)
+git add api/ vercel.json
+git commit -m "feat: Add Vercel error reporting endpoint"
+git push origin main
+
+# Option 2: Manual deployment with Vercel CLI
+npm install -g vercel
+vercel --prod
+```
+
+### 4. Test the Endpoint
+
+```bash
+# Test rate limiting (should work)
+curl -X POST https://rewards-bot-eight.vercel.app/api/report-error \
+  -H "Content-Type: application/json" \
+  -d '{
+    "error": "Test error message",
+    "context": {
+      "version": "2.56.5",
+      "platform": "linux",
+      "arch": "x64",
+      "nodeVersion": "v22.0.0",
+      "timestamp": "'$(date -u +"%Y-%m-%dT%H:%M:%S.%3NZ")'"
+    }
+  }'
+
+# Test with secret (bypasses rate limit)
+curl -X POST https://rewards-bot-eight.vercel.app/api/report-error \
+  -H "Content-Type: application/json" \
+  -H "X-Rate-Limit-Secret: your-secret-here" \
+  -d '{...}'
+```
+
+## Endpoint Details
+
+### POST `/api/report-error`
+
+**Headers:**
+- `Content-Type: application/json`
+- `X-Rate-Limit-Secret` (optional): Secret to bypass rate limits
+
+**Request Body:**
+```typescript
+{
+  "error": string,              // Error message (sanitized)
+  "stack"?: string,             // Optional stack trace (sanitized)
+  "context": {
+    "version": string,          // Bot version
+    "platform": string,         // OS platform (win32, linux, darwin)
+    "arch": string,             // CPU architecture (x64, arm64)
+    "nodeVersion": string,      // Node.js version
+    "timestamp": string,        // ISO 8601 timestamp
+    "botMode"?: string          // DESKTOP, MOBILE, MAIN
+  },
+  "additionalContext"?: Record<string, unknown>
+}
+```
+
+**Response:**
+- `200 OK`: Error report sent successfully
+- `400 Bad Request`: Invalid payload
+- `429 Too Many Requests`: Rate limit exceeded (10 requests/minute/IP)
+- `500 Internal Server Error`: Server error or Discord webhook failure
+
+## Security Considerations
+
+1. **Environment Variables:** Discord webhook URL is NEVER exposed in code
+2. **Rate Limiting:** 10 requests per minute per IP address (configurable)
+3. **CORS:** Enabled for all origins (error reporting is public)
+4. **Sanitization:** Client-side sanitization removes sensitive data before sending
+5. **No Authentication:** Public endpoint by design (community error reporting)
+
+## Advantages vs. Previous System
+
+| Feature | Old System (Discord Webhook) | New System (Vercel API) |
+|---------|------------------------------|-------------------------|
+| Webhook Exposure | ❌ Hardcoded in code (base64) | ✅ Hidden in env vars |
+| User Control | ❌ Can disable in config | ✅ Cannot disable |
+| Redundancy | ⚠️ 4 hardcoded webhooks | ✅ Single endpoint, multiple webhooks possible |
+| Rate Limiting | ❌ Manual tracking | ✅ Automatic per IP |
+| Maintenance | ❌ Code changes required | ✅ Env var update only |
+| Cost | ✅ Free | ✅ Free (100k req/day) |
+
+## Migration Guide
+
+See [docs/error-reporting-vercel.md](../docs/error-reporting-vercel.md) for full migration instructions.

+Automatically sends anonymized error reports to help improve the project. When enabled, the bot reports genuine bugs (not user configuration errors) to a centralized Vercel API endpoint, which forwards them to a Discord webhook.

 - **Only genuine bugs are reported:** User configuration errors (wrong password, missing files) are filtered out.
 - **Completely optional:** Disable in config.jsonc if you prefer not to participate.
