+# Zoho OAuth Setup Instructions
+
+## Prerequisites
+
+- Zoho CRM account
+- Admin access to create OAuth applications
+- Access to staging server terminal
+
+## Step 1: Create Zoho OAuth Application
+
+1. Go to [Zoho API Console](https://api-console.zoho.com/)
+2. Click "Add Client" or "Create New Client"
+3. Choose "Web Based" application type
+4. Fill in the details:
+   - **Client Name**: HVAC Community Events
+   - **Homepage URL**: https://upskillhvac.com
+   - **Authorized Redirect URIs**: http://localhost:8080/callback
+   - **Description**: WordPress integration for HVAC event management
+
+5. Click "Create" and save the credentials:
+   - Client ID
+   - Client Secret
+
+## Step 2: Configure Environment Variables
+
+Add to your `.env` file:
+```
+ZOHO_CLIENT_ID=your_client_id_here
+ZOHO_CLIENT_SECRET=your_client_secret_here
+```
+
+## Step 3: Run OAuth Setup
+
+From your terminal:
+
+```bash
+cd /Users/ben/dev/upskill-event-manager/wordpress-dev
+./bin/zoho-setup-complete.sh
+```
+
+This script will:
+1. Start a local callback server
+2. Generate the authorization URL
+3. Open your browser for Zoho login
+4. Handle the OAuth callback
+5. Save the tokens
+
+## Step 4: Complete Authorization
+
+1. When the browser opens, log in to Zoho
+2. Review the permissions requested:
+   - CRM Settings access
+   - CRM Modules access  
+   - CRM Users access
+   - CRM Organization access
+3. Click "Accept" or "Allow"
+4. You'll be redirected to localhost:8080/callback
+5. Copy the authorization code from the page
+6. Return to terminal and paste the code
+
+## Step 5: Verify Setup
+
+The script will:
+- Exchange the code for tokens
+- Test the connection
+- Save configuration to `zoho-config.php`
+- Display success message
+
+## Manual Setup (Alternative)
+
+If the automated script doesn't work:
+
+1. Start callback server:
+```bash
+cd wordpress/wp-content/plugins/hvac-community-events/includes/zoho
+php -S localhost:8080 callback-server.php
+```
+
+2. Generate authorization URL:
+```bash
+php test-integration.php
+```
+
+3. Open the URL in your browser
+4. Complete authorization
+5. Copy the code and paste when prompted
+
+## Testing the Integration
+
+After setup, test on staging:
+
+1. Go to WordPress Admin
+2. Navigate to HVAC Community Events → Zoho CRM Sync
+3. Click "Test Connection"
+4. In staging mode, you'll see simulation results only
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"Client authentication failed"**
+   - Double-check Client ID and Secret
+   - Ensure no extra spaces in .env file
+
+2. **"Invalid redirect URI"**
+   - Make sure redirect URI in Zoho matches exactly: http://localhost:8080/callback
+   - No trailing slash
+
+3. **Connection refused on localhost:8080**
+   - Ensure no other service is using port 8080
+   - Try a different port if needed
+
+4. **Token expired**
+   - Tokens auto-refresh, but if issues persist, re-run setup
+
+### Debug Mode
+
+Enable debug logging:
+```php
+define('ZOHO_DEBUG_MODE', true);
+define('ZOHO_LOG_FILE', '/path/to/debug.log');
+```
+
+## Security Notes
+
+- Never commit .env or zoho-config.php to version control
+- Tokens are stored encrypted in WordPress options
+- Refresh tokens are used for long-term access
+- Staging mode prevents accidental production syncs
+
+## Support
+
+For issues:
+1. Check debug logs
+2. Verify OAuth application settings
+3. Review Zoho API documentation
+4. Contact development team
