+# Extension Points
+
+## Overview
+
+Extension Points in ServiceNow provide a powerful mechanism for creating extensible, plugin-based architectures. They allow you to define interfaces that can be implemented by multiple extensions, enabling dynamic behavior selection at runtime without modifying core code.
+
+## What are Extension Points?
+
+Extension Points follow the interface-implementation pattern where:
+- **Extension Point (Interface)**: Defines a contract with methods that implementations must provide
+- **Extensions (Implementations)**: Concrete classes that implement the interface methods
+- **Consumer**: Code that discovers and invokes extensions dynamically using `GlideScriptedExtensionPoint`
+
+This pattern is ideal for:
+- Creating pluggable notification systems
+- Building extensible validation frameworks
+- Implementing strategy patterns
+- Supporting multi-tenant customizations
+- Enabling third-party integrations
+
+## Files in this Directory
+
+### 1. CustomNotificationHandlerInterfaceExtension.js
+Defines the base interface (Extension Point) for notification handlers.
+
+**Key Methods:**
+- `initialize(record, config)`: Constructor for setting up the handler
+- `process()`: Must be implemented - processes the notification
+- `shouldNotify()`: Must be implemented - validates if notification should be sent
+- `handles(notificationSystem)`: Determines if this implementation applies to a specific system
+
+### 2. CustomNotificationHandlerInterfaceImplementation.js
+Concrete implementation of the notification handler interface for email notifications.
+
+**Features:**
+- Email notification processing using `GlideEmailOutbound`
+- Priority-based notification criteria
+- Template-based subject and body generation
+- Error handling and logging
+- Configurable recipients and templates
+
+### 3. ExtensionPointCallingExample.js
+Demonstrates how to discover and invoke extension point implementations dynamically.
+
+**Pattern:**
+```javascript
+var eps = new GlideScriptedExtensionPoint().getExtensions("scope.InterfaceName");
+for (var i = 0; i < eps.length; i++) {
+    if (eps[i].handles("criteria")) {
+        eps[i].process();
+    }
+}
+```
+
+## How to Use Extension Points
+
+### Step 1: Create the Extension Point (Interface)
+
+Create a Script Include with the interface definition:
+
+```javascript
+var CustomNotificationHandlerInterface = Class.create();
+CustomNotificationHandlerInterface.prototype = {
+    initialize: function(record, config) {
+        this.record = record;
+        this.config = config || {};
+    },
+    
+    process: function() {
+        throw new Error('process() must be implemented by extension');
+    },
+    
+    shouldNotify: function() {
+        throw new Error('shouldNotify() must be implemented by extension');
+    },
+    
+    handles: function(notificationSystem) {
+        return notificationSystem == "DEFAULT";
+    },
+    
+    type: 'CustomNotificationHandlerInterface'
+};
+```
+
+**Important Configuration:**
+- Set **API Name** to match the type (e.g., `CustomNotificationHandlerInterface`)
+- Check **Client callable** if needed from client-side
+- Set appropriate **Application** scope
+
+### Step 2: Create Extension Point Record
+
+1. Navigate to **System Definition > Extension Points**
+2. Create a new Extension Point record:
+   - **Name**: Descriptive name (e.g., "Custom Notification Handler Interface")
+   - **API name**: Full scoped name (e.g., `x_snc_extension_p_0.CustomNotificationHandlerInterface`)
+   - **Example implementation**: Reference your interface Script Include
+
+### Step 3: Create Implementations (Extensions)
+
+Create Script Includes that extend the interface:
+
+```javascript
+var EmailNotificationHandler = Class.create();
+EmailNotificationHandler.prototype = Object.extendsObject(CustomNotificationHandlerInterface, {
+    
+    process: function() {
+        // Implementation-specific logic
+        var email = new GlideEmailOutbound();
+        email.setSubject(this._buildSubject());
+        email.setBody(this._buildBody());
+        email.send();
+        
+        return { success: true, message: 'Email sent' };
+    },
+    
+    shouldNotify: function() {
+        // Custom validation logic
+        return this.record.getValue('priority') <= 3;
+    },
+    
+    handles: function(notificationSystem) {
+        return notificationSystem == "Email";
+    },
+    
+    type: 'EmailNotificationHandler'
+});
+```
+
+### Step 4: Register Extensions
+
+1. Navigate to **System Definition > Extensions**
+2. Create Extension records for each implementation:
+   - **Extension point**: Select your Extension Point
+   - **Name**: Implementation name
+   - **Implementation**: Reference your implementation Script Include
+
+### Step 5: Invoke Extensions Dynamically
+
+Use `GlideScriptedExtensionPoint` to discover and execute extensions:
+
+```javascript
+// Get all extensions for the interface
+var eps = new GlideScriptedExtensionPoint().getExtensions("x_snc_extension_p_0.CustomNotificationHandlerInterface");
+
+// Iterate and invoke matching extensions
+for (var i = 0; i < eps.length; i++) {
+    gs.info("Checking extension: " + eps[i].type);
+    
+    if (eps[i].handles("Email")) {
+        var result = eps[i].process();
+        gs.info("Result: " + JSON.stringify(result));
+    }
+}
+```
+
+## Best Practices
+
+### 1. Interface Design
+- Define clear contracts with well-documented methods
+- Use JSDoc comments for all interface methods
+- Throw errors for unimplemented required methods
+- Provide sensible defaults in the base interface
+
+### 2. Implementation Guidelines
+- Always implement all required interface methods
+- Use the `handles()` method to control when implementation applies
+- Include comprehensive error handling
+- Return consistent result objects
+- Log important operations for debugging
+
+### 3. Naming Conventions
+- Use descriptive names for Extension Points
+- Follow ServiceNow naming standards
+- Include scope prefix in API names
+- Use consistent naming across interface and implementations
+
+### 4. Performance Considerations
+- Cache extension instances when possible
+- Avoid heavy processing in `handles()` method
+- Use early returns to skip unnecessary processing
+- Consider lazy initialization for expensive resources
+
+### 5. Testing
+- Test each implementation independently
+- Verify `handles()` logic with various inputs
+- Test error handling and edge cases
+- Validate behavior when no extensions match
+
+## Common Use Cases
+
+### 1. Multi-Channel Notifications
+Create extensions for Email, SMS, Slack, Teams, etc., all implementing a common notification interface.
+
+### 2. Validation Frameworks
+Build extensible validation systems where different validators can be plugged in based on record type or business rules.
+
+### 3. Data Transformation
+Implement multiple transformation strategies that can be selected dynamically based on data source or format.
+
+### 4. Integration Adapters
+Create adapters for different external systems, all conforming to a common integration interface.
+
+### 5. Approval Workflows
+Build flexible approval mechanisms where different approval strategies can be applied based on conditions.
+
+## Troubleshooting
+
+### Extensions Not Found
+- Verify Extension Point API name matches exactly
+- Check that Extension records are active
+- Ensure Script Includes are in the correct application scope
+- Verify no typos in scope prefix
+
+### Methods Not Executing
+- Confirm `handles()` method returns true for your criteria
+- Check for errors in implementation code
+- Verify Script Include is set to correct type
+- Review logs for error messages
+
+### Performance Issues
+- Reduce number of extensions if possible
+- Optimize `handles()` method logic
+- Consider caching extension instances
+- Profile code to identify bottlenecks

+## Example Scenarios
+
+### Scenario 1: Priority-Based Email Notifications
+Use the provided implementation to send email notifications only for high-priority incidents (priority 1-3).
+
+### Scenario 2: Multi-System Notification Router
+Create multiple implementations (Email, SMS, Slack) and route notifications based on user preferences or incident severity.
+
+### Scenario 3: Custom Business Logic
+Extend the interface to add custom validation rules, approval logic, or data transformation specific to your organization.
+
+## Contributing
