+# Google Secret Manager Integration Guide
+
+This guide explains how to integrate Google Cloud Secret Manager with your Node.js application to securely manage environment variables.
+
+## Overview
+
+The Google Secret Manager integration allows you to:
+- Store sensitive configuration values (passwords, API keys, tokens) in Google Cloud Secret Manager
+- Load secrets at application startup and merge them with your existing environment variables
+- Maintain backward compatibility with `.env` files for local development
+- Use minimal code changes - existing `process.env.VARIABLE_NAME` access continues to work
+
+## Prerequisites
+
+1. **Google Cloud Project** with Secret Manager API enabled
+2. **Service Account** with Secret Manager Secret Accessor role
+3. **Authentication** - Service account credentials configured (via `GCP_KEY_FILE` or default credentials)
+
+## Setup Instructions
+
+### 1. Enable Secret Manager API
+
+```bash
+gcloud services enable secretmanager.googleapis.com --project=YOUR_PROJECT_ID
+```
+
+### 2. Create Secrets in Google Secret Manager
+
+Create secrets using the Google Cloud Console or gcloud CLI:
+
+```bash
+# Example: Create a database password secret
+echo -n "your-secure-password" | gcloud secrets create DB_PASSWORD \
+  --project=YOUR_PROJECT_ID \
+  --data-file=-
+
+# Example: Create a JWT secret
+echo -n "your-jwt-secret-key" | gcloud secrets create JWT_SECRET \
+  --project=YOUR_PROJECT_ID \
+  --data-file=-
+
+# Grant service account access to secrets
+gcloud secrets add-iam-policy-binding DB_PASSWORD \
+  --member="serviceAccount:YOUR_SERVICE_ACCOUNT@YOUR_PROJECT.iam.gserviceaccount.com" \
+  --role="roles/secretmanager.secretAccessor" \
+  --project=YOUR_PROJECT_ID
+```
+
+### 3. Configure Environment Variables
+
+Add the following to your `.env` file:
+
+```env
+# Google Secret Manager Configuration
+USE_GOOGLE_SECRET_MANAGER=true
+GCP_PROJECT_ID=your-project-id
+
+# Optional: Prefix for all secret names (e.g., "prod" -> looks for "prod-DB_PASSWORD")
+GCP_SECRET_PREFIX=
+
+# Optional: JSON file mapping secret names to env var names
+GCP_SECRET_MAP_FILE=./secret-map.json
+```
+
+**Important Notes:**
+- Set `USE_GOOGLE_SECRET_MANAGER=true` to enable the integration
+- `GCP_PROJECT_ID` must be set (same as used for GCS/Vertex AI)
+- `GCP_KEY_FILE` should already be configured for other GCP services
+- When `USE_GOOGLE_SECRET_MANAGER=false` or not set, the app uses `.env` file only
+
+### 4. Secret Name Mapping
+
+By default, secrets in Google Secret Manager are automatically mapped to environment variables:
+- Secret name: `DB_PASSWORD` → Environment variable: `DB_PASSWORD`
+- Secret name: `db-password` → Environment variable: `DB_PASSWORD` (hyphens converted to underscores, uppercase)
+- Secret name: `jwt-secret-key` → Environment variable: `JWT_SECRET_KEY`
+
+#### Custom Mapping (Optional)
+
+If you need custom mappings, create a JSON file (e.g., `secret-map.json`):
+
+```json
+{
+  "db-password-prod": "DB_PASSWORD",
+  "jwt-secret-key": "JWT_SECRET",
+  "okta-client-secret-prod": "OKTA_CLIENT_SECRET"
+}
+```
+
+Then set in `.env`:
+```env
+GCP_SECRET_MAP_FILE=./secret-map.json
+```
+
+### 5. Secret Prefix (Optional)
+
+If all your secrets share a common prefix:
+
+```env
+GCP_SECRET_PREFIX=prod
+```
+
+This will look for secrets named `prod-DB_PASSWORD`, `prod-JWT_SECRET`, etc.
+
+## How It Works
+
+1. **Application Startup:**
+   - `.env` file is loaded first (provides fallback values)
+   - If `USE_GOOGLE_SECRET_MANAGER=true`, secrets are fetched from Google Secret Manager
+   - Secrets are merged into `process.env`, overriding `.env` values if they exist
+   - Application continues with merged environment variables
+
+2. **Fallback Behavior:**
+   - If Secret Manager is disabled or fails, the app falls back to `.env` file
+   - No errors are thrown - the app continues with available configuration
+   - Logs indicate whether secrets were loaded successfully
+
+3. **Existing Code Compatibility:**
+   - No changes needed to existing code
+   - Continue using `process.env.VARIABLE_NAME` as before
+   - Secrets from GCS automatically populate `process.env`
+
+## Default Secrets Loaded
+
+The service automatically attempts to load these common secrets (if they exist in Secret Manager):
+
+**Database:**
+- `DB_HOST`, `DB_PORT`, `DB_NAME`, `DB_USER`, `DB_PASSWORD`
+
+**Authentication:**
+- `JWT_SECRET`, `REFRESH_TOKEN_SECRET`, `SESSION_SECRET`
+
+**SSO/Okta:**
+- `OKTA_DOMAIN`, `OKTA_CLIENT_ID`, `OKTA_CLIENT_SECRET`, `OKTA_API_TOKEN`
+
+**Email:**
+- `SMTP_HOST`, `SMTP_PORT`, `SMTP_USER`, `SMTP_PASSWORD`
+
+**Web Push (VAPID):**
+- `VAPID_PUBLIC_KEY`, `VAPID_PRIVATE_KEY`
+
+**Logging:**
+- `LOKI_HOST`, `LOKI_USER`, `LOKI_PASSWORD`
+
+### Loading Custom Secrets
+
+To load additional secrets, modify the code:
+
+```typescript
+// In server.ts or app.ts
+import { googleSecretManager } from './services/googleSecretManager.service';
+
+// Load default secrets + custom ones
+await googleSecretManager.loadSecrets([
+  'DB_PASSWORD',
+  'JWT_SECRET',
+  'CUSTOM_API_KEY',  // Your custom secret
+  'CUSTOM_SECRET_2'
+]);
+```
+
+Or load a single secret on-demand:
+
+```typescript
+import { googleSecretManager } from './services/googleSecretManager.service';
+
+const apiKey = await googleSecretManager.getSecretValue('CUSTOM_API_KEY', 'API_KEY');
+```
+
+## Security Best Practices
+
+1. **Service Account Permissions:**
+   - Grant only `roles/secretmanager.secretAccessor` role
+   - Use separate service accounts for different environments
+   - Never grant `roles/owner` or `roles/editor` to service accounts
+
+2. **Secret Rotation:**
+   - Rotate secrets regularly in Google Secret Manager
+   - The app automatically uses the `latest` version of each secret
+   - No code changes needed when secrets are rotated
+
+3. **Environment Separation:**
+   - Use different Google Cloud projects for dev/staging/prod
+   - Use `GCP_SECRET_PREFIX` to namespace secrets by environment
+   - Never commit `.env` files with production secrets to version control
+
+4. **Access Control:**
+   - Use IAM policies to control who can read secrets
+   - Enable audit logging for secret access
+   - Regularly review secret access logs
+
+## Troubleshooting
+
+### Secrets Not Loading
+
+**Check logs for:**
+```
+[Secret Manager] Google Secret Manager is disabled (USE_GOOGLE_SECRET_MANAGER != true)
+[Secret Manager] GCP_PROJECT_ID not set, skipping Google Secret Manager
+[Secret Manager] Failed to load secrets: [error message]
+```
+
+**Common issues:**
+1. `USE_GOOGLE_SECRET_MANAGER` not set to `true`
+2. `GCP_PROJECT_ID` not configured
+3. Service account lacks Secret Manager permissions
+4. Secrets don't exist in Secret Manager
+5. Incorrect secret names (check case sensitivity)
+
+### Service Account Authentication
+
+Ensure service account credentials are available:
+- Set `GCP_KEY_FILE` to point to service account JSON file
+- Or configure Application Default Credentials (ADC)
+- Test with: `gcloud auth application-default login`
+
+### Secret Not Found
+
+If a secret doesn't exist in Secret Manager:
+- The app logs a debug message and continues
+- Falls back to `.env` file value
+- This is expected behavior - not all secrets need to be in GCS
+
+### Debugging
+
+Enable debug logging by setting:
+```env
+LOG_LEVEL=debug
+```
+
+This will show detailed logs about which secrets are being loaded.
+
+## Example Configuration
+
+**Local Development (.env):**
+```env
+USE_GOOGLE_SECRET_MANAGER=false
+DB_PASSWORD=local-dev-password
+JWT_SECRET=local-jwt-secret
+```
+
+**Production (.env):**
+```env
+USE_GOOGLE_SECRET_MANAGER=true
+GCP_PROJECT_ID=re-platform-workflow-dealer
+GCP_SECRET_PREFIX=prod
+GCP_KEY_FILE=./credentials/service-account.json
+# DB_PASSWORD and other secrets loaded from GCS
+```
+
+## Migration Strategy
+
+1. **Phase 1: Setup**
+   - Create secrets in Google Secret Manager
+   - Keep `.env` file with current values (as backup)
+
+2. **Phase 2: Test**
+   - Set `USE_GOOGLE_SECRET_MANAGER=true` in development
+   - Verify secrets are loaded correctly
+   - Test application functionality
+
+3. **Phase 3: Production**
+   - Deploy with `USE_GOOGLE_SECRET_MANAGER=true`
+   - Monitor logs for secret loading success
+   - Remove sensitive values from `.env` file (keep placeholders)
+
+4. **Phase 4: Cleanup**
+   - Remove production secrets from `.env` file
+   - Ensure all secrets are in Secret Manager
+   - Document secret names and mappings

+ * Configuration:
+ * - Set USE_GOOGLE_SECRET_MANAGER=true to enable (default: false)
+ * - Set GCP_PROJECT_ID to your Google Cloud Project ID
+ * - Set GCP_SECRET_PREFIX to prefix all secret names (optional, default: empty)
+ * - Set GCP_SECRET_MAP_FILE to map secret names to env vars (optional, see format below)
+ * 
+ * Secret Name Mapping:
+ * - By default, secrets are mapped to env vars with the same name (uppercase)
+ * - Example: secret "db_password" -> process.env.DB_PASSWORD
+ * - Use GCP_SECRET_MAP_FILE to provide a JSON mapping file for custom mappings
+ * 
+ * Fallback:
+ * - If Google Secret Manager is disabled or fails, falls back to .env file
+ * - Existing environment variables take precedence unless explicitly overridden
