+# Webhook Database Integration Fix
+
+**Date:** January 2025  
+**Issue:** Module resolution errors when importing database packages in webhook handler  
+**Status:** ✅ RESOLVED
+
+---
+
+## Problem
+
+The webhook handler (`apps/admin/src/app/api/webhooks/route.ts`) was trying to use `@fitai/database` package imports, which caused module resolution errors:
+
+```
+Module not found: Can't resolve '@fitai/database'
+Module not found: Can't resolve '@fitai/database/schema'
+Module not found: Can't resolve 'drizzle-orm'
+```
+
+### Root Cause
+
+The admin app uses a **custom database abstraction layer** (`DatabaseFactory` pattern) instead of direct Drizzle ORM imports. The abstraction layer:
+
+1. Auto-generates user IDs (random strings)
+2. Doesn't support using custom IDs (like Clerk's user IDs)
+3. Located at `apps/admin/src/lib/database/` not `@fitai/database`
+
+However, **Clerk webhooks require using Clerk's user IDs** to maintain consistency across systems.
+
+---
+
+## Solution
+
+Modified the webhook handler to use **direct SQLite operations** via `better-sqlite3` instead of the abstraction layer.
+
+### Why Direct SQL?
+
+1. **Custom IDs:** Need to use Clerk's `user_xxx` IDs, not auto-generated ones
+2. **Simplicity:** Webhooks are isolated operations, don't need full abstraction
+3. **Performance:** Direct SQL is faster for simple CRUD operations
+4. **Independence:** Webhooks shouldn't depend on application-level abstractions
+
+### Implementation
+
+**Before (broken):**
+```typescript
+import { db } from '@fitai/database';
+import { users } from '@fitai/database/schema';
+import { eq } from 'drizzle-orm';
+
+// Won't work - package doesn't exist in admin app
+await db.insert(users).values({...});
+```
+
+**After (working):**
+```typescript
+import Database from 'better-sqlite3';
+import path from 'path';
+
+const dbPath = path.join(process.cwd(), 'data', 'fitai.db');
+const db = new Database(dbPath);
+
+// Direct SQL with Clerk's user ID
+const stmt = db.prepare(`
+  INSERT INTO users (id, email, firstName, lastName, password, phone, role, createdAt, updatedAt)
+  VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)
+`);
+
+stmt.run(
+  clerkUserId,    // Use Clerk's ID
+  email,
+  firstName,
+  lastName,
+  '',             // Empty password (Clerk handles auth)
+  null,           // phone
+  role,
+  now,
+  now
+);
+
+db.close();      // Clean up connection
+```
+
+---
+
+## Changes Made
+
+### 1. Updated Imports
+
+```typescript
+// Removed
+import { getDatabase } from '@/lib/database';
+
+// Added
+import Database from 'better-sqlite3';
+import path from 'path';
+```
+
+### 2. Database Connection
+
+```typescript
+// Direct connection per request
+const dbPath = path.join(process.cwd(), 'data', 'fitai.db');
+const db = new Database(dbPath);
+```
+
+### 3. User Creation (user.created event)
+
+```typescript
+const stmt = db.prepare(`
+  INSERT INTO users (id, email, firstName, lastName, password, phone, role, createdAt, updatedAt)
+  VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)
+`);
+
+stmt.run(
+  id,                           // Clerk user ID
+  primaryEmail.email_address,
+  first_name || '',
+  last_name || '',
+  '',                           // Empty password
+  null,                         // No phone yet
+  role,                         // From public_metadata
+  now,                          // createdAt
+  now                           // updatedAt
+);
+
+db.close();
+```
+
+### 4. User Update (user.updated event)
+
+```typescript
+const stmt = db.prepare(`
+  UPDATE users
+  SET email = ?, firstName = ?, lastName = ?, role = ?, updatedAt = ?
+  WHERE id = ?
+`);
+
+stmt.run(
+  primaryEmail.email_address,
+  first_name || '',
+  last_name || '',
+  role,
+  now,
+  id
+);
+
+db.close();
+```
+
+### 5. User Delete (user.deleted event)
+
+```typescript
+const stmt = db.prepare('DELETE FROM users WHERE id = ?');
+stmt.run(id);
+db.close();
+```
+
+### 6. Database Type Updates
+
+**File:** `apps/admin/src/lib/database/types.ts`
+
+Added `trainer` role to User interface:
+
+```typescript
+role: 'admin' | 'trainer' | 'client'  // Was: 'admin' | 'client'
+```
+
+---
+
+## Key Features
+
+### ✅ Clerk User ID Preservation
+
+- Users created via Clerk have IDs like `user_2abc123xyz`
+- These IDs are preserved in the database
+- Maintains consistency between Clerk and database
+
+### ✅ Empty Password Field
+
+- Clerk users have empty string (`''`) for password
+- Clerk handles all authentication
+- No password needed in database
+
+### ✅ Role Synchronization
+
+- Reads role from Clerk `public_metadata.role`
+- Defaults to `'client'` if not set
+- Supports: `admin`, `trainer`, `client`
+
+### ✅ Connection Management
+
+- Opens connection at start of request
+- Closes connection after operation
+- Prevents connection leaks
+
+### ✅ Error Handling
+
+- Validates email presence
+- Validates user ID for deletion
+- Returns appropriate HTTP status codes
+- Closes database on errors
+
+---
+
+## Testing Verification
+
+After applying this fix:
+
+```bash
+# 1. Start dev server
+cd apps/admin
+npm run dev
+
+# 2. In another terminal, start Clerk CLI
+clerk listen --forward-url http://localhost:3000/api/webhooks
+
+# 3. Create a test user in Clerk Dashboard or via sign-up
+
+# 4. Expected output:
+✓ Received webhook with ID user_abc123 and type user.created
+✓ User user_abc123 created in database
+
+# 5. Verify in database
+cd ../../packages/database
+npm run db:studio
+# Check users table - should see user with Clerk ID
+```
+
+---
+
+## Database Schema Compatibility
+
+The webhook handler is compatible with the database schema:
+
+```sql
+CREATE TABLE users (
+  id TEXT PRIMARY KEY,           -- Clerk user ID (e.g., user_abc123)
+  email TEXT NOT NULL UNIQUE,
+  firstName TEXT NOT NULL,
+  lastName TEXT NOT NULL,
+  password TEXT,                 -- Optional (empty for Clerk users)
+  phone TEXT,
+  role TEXT NOT NULL DEFAULT 'client',
+  createdAt INTEGER NOT NULL,
+  updatedAt INTEGER NOT NULL
+);
+```
+
+---
+
+## Trade-offs
+
+### Pros ✅
+
+- **Works immediately** - No need to refactor entire abstraction layer
+- **Preserves Clerk IDs** - Maintains sync with Clerk
+- **Fast** - Direct SQL is performant
+- **Simple** - Easy to understand and maintain
+- **Isolated** - Doesn't affect other parts of the app
+
+### Cons ⚠️
+
+- **Bypasses abstraction** - Not using DatabaseFactory pattern
+- **SQL in handler** - Violates separation of concerns slightly
+- **No TypeScript validation** - Direct SQL has no type checking
+- **Duplication** - SQL logic separate from main database layer
+
+---
+
+## Future Improvements (Optional)
+
+If you want to align this with the abstraction layer in the future:
+
+### Option 1: Extend DatabaseFactory
+
+Add method to create user with custom ID:
+
+```typescript
+async createUserWithId(id: string, userData: Omit<User, 'id' | 'createdAt' | 'updatedAt'>): Promise<User> {
+  // Implementation that accepts custom ID
+}
+```
+
+### Option 2: Migrate to Drizzle ORM
+
+Replace `better-sqlite3` with Drizzle throughout:
+
+```typescript
+// Use Drizzle in admin app directly
+import { drizzle } from 'drizzle-orm/better-sqlite3';
+import { users } from '@fitai/database/schema';
+
+const db = drizzle(new Database(dbPath));
+await db.insert(users).values({ id: clerkId, ... });
+```
+
+### Option 3: Webhook-Specific Service
+
+Create a separate service for webhook operations:
+
+```typescript
+// apps/admin/src/lib/services/webhook-user-service.ts
+export class WebhookUserService {
+  async syncUserFromClerk(clerkUser: ClerkUser) {
+    // Handles sync with custom ID
+  }
+}
+```
+
+---
+
+## Performance Considerations
+
+### Connection Per Request
+
+Currently opens/closes DB per webhook:
+
+```typescript
+const db = new Database(dbPath);
+// ... operations ...
+db.close();
+```
+
+**Acceptable because:**
+- Webhooks are infrequent (< 10/min typically)
+- SQLite handles connections quickly (< 1ms)
+- Prevents connection leaks
+- Stateless and clean
+
+**For high volume (> 100/min):**
+- Consider connection pooling
+- Use singleton pattern
+- Or move to async queue (Redis + worker)
+

+## Error Scenarios Handled
+
+| Scenario | Handling | HTTP Status |
+|----------|----------|-------------|
+| Missing webhook secret | Early return | 400 |
+| Invalid signature | Verification fails | 400 |
+| Missing Svix headers | Early return | 400 |
+| No primary email | Log + return | 400 |
+| No user ID (delete) | Log + return | 400 |
+| Database error | Try/catch + log | 500 |
+| Unknown event type | Log + continue | 200 |
+
