+### DEI Login (Email-based Authentication) 🆕
+
+The DEI login method provides email-based authentication for DEI platform users. This method automatically handles JWT token extraction and secure storage.
+
+```swift
+// Completion handler approach
+WarplySDK.shared.deiLogin(
+    email: "user@example.com",
+    completion: { response in
+        if let response = response, response.getStatus == 1 {
+            print("DEI login successful")
+            // User is now authenticated - proceed with authenticated operations
+            // Tokens are automatically stored and managed by the SDK
+        } else {
+            print("DEI login failed")
+        }
+    },
+    failureCallback: { errorCode in
+        print("DEI login failed with error: \(errorCode)")
+        // Handle specific error codes

+        default:
+            print("Unknown error occurred")
+        }
+    }
+)
+
+// Async/await approach (Recommended)
+Task {
+    do {
+        let response = try await WarplySDK.shared.deiLogin(email: "user@example.com")
+        if response.getStatus == 1 {

+            // User is now authenticated - proceed with authenticated operations
+            // Access other authenticated endpoints like getCoupons, getProfile, etc.
+        } else {
+            print("DEI login failed")
+        }
+    } catch let error as WarplyError {
+        switch error {

+**Key Features:**
+- ✅ **Email-based authentication** - No complex credentials required
+- ✅ **Automatic token management** - JWT tokens extracted and stored securely
+- ✅ **Future-ready design** - Handles refresh tokens (currently null, will be valid later)
+- ✅ **Comprehensive error handling** - Detailed error codes and messages
+- ✅ **Analytics integration** - Success/failure events tracked automatically

+# DEI Login Implementation Test
+
+## Implementation Summary
+
+The DEI login functionality has been successfully implemented with the following components:
+
+### 1. Endpoint Configuration (Endpoints.swift)
+- ✅ Added `deiLogin(email: String)` case to Endpoint enum
+- ✅ Configured path: `/partners/dei/app_login`
+- ✅ Configured method: POST
+- ✅ Configured parameters: `["email": email]`
+- ✅ Configured authentication: `.standard` (no authorization header)
+- ✅ Set `requiresAuthentication: false`
+
+### 2. Network Service Method (NetworkService.swift)
+- ✅ Added `deiLogin(email: String)` method in NetworkService
+- ✅ Implemented comprehensive error handling
+- ✅ Added response validation (status == 1)
+- ✅ Added token extraction and validation
+- ✅ Added automatic TokenModel creation and database storage
+- ✅ Added detailed logging for debugging
+
+### 3. Public SDK Methods (WarplySDK.swift)
+- ✅ Added completion handler variant: `deiLogin(email:completion:failureCallback:)`
+- ✅ Added async/await variant: `deiLogin(email:) async throws`
+- ✅ Added comprehensive documentation with examples
+- ✅ Added analytics events for success/failure tracking
+- ✅ Added state management (clears CCMS campaigns)
+- ✅ Added proper error handling and conversion
+
+## Key Features Implemented
+
+### Authentication Flow
+1. **Email-based authentication** - No authorization header required
+2. **JWT token extraction** - Extracts access_token and refresh_token from nested response
+3. **Automatic token storage** - Stores tokens in database using TokenModel
+4. **Future-ready design** - Handles null refresh tokens (will be valid later)
+
+### Error Handling
+1. **Status validation** - Ensures response status == 1
+2. **Token validation** - Ensures access_token exists and is not empty
+3. **Network error handling** - Comprehensive error mapping and logging
+4. **Analytics tracking** - Success/failure events for monitoring
+
+### Response Structure Support
+Expected response format:
+```json
+{
+  "status": 1,
+  "tokens": {
+    "access_token": "eyJ...",
+    "refresh_token": null,
+    "client_id": "...",
+    "client_secret": "..."
+  }
+}
+```
+
+## Usage Examples
+
+### Completion Handler Variant
+```swift
+WarplySDK.shared.deiLogin(
+    email: "user@example.com",
+    completion: { response in
+        if let response = response, response.getStatus == 1 {
+            print("DEI login successful")
+            // User is now authenticated - proceed with authenticated operations
+        } else {
+            print("DEI login failed")
+        }
+    },
+    failureCallback: { errorCode in
+        print("DEI login failed with error: \(errorCode)")
+    }
+)
+```
+
+### Async/Await Variant
+```swift
+Task {
+    do {
+        let response = try await WarplySDK.shared.deiLogin(email: "user@example.com")
+        if response.getStatus == 1 {
+            print("DEI login successful")
+            // User is now authenticated - proceed with authenticated operations
+        } else {
+            print("DEI login failed")
+        }
+    } catch {
+        print("DEI login failed with error: \(error)")
+    }
+}
+```
+
+## Integration with Existing Framework
+
+### Token Management
+- ✅ Integrates with existing TokenModel system
+- ✅ Integrates with DatabaseManager for secure storage
+- ✅ Integrates with TokenRefreshManager for future token refresh
+- ✅ Integrates with NetworkService for automatic token usage
+
+### Analytics
+- ✅ Follows existing analytics patterns
+- ✅ Posts success/failure events to Dynatrace
+- ✅ Uses existing event system (SwiftEventBus + EventDispatcher)
+
+### Error Handling
+- ✅ Uses existing WarplyError system
+- ✅ Follows existing error mapping patterns
+- ✅ Provides consistent error codes and messages
+
+## Testing Checklist
+
+### Basic Functionality
+- [ ] Test successful login with valid email
+- [ ] Test failed login with invalid email
+- [ ] Test network error handling
+- [ ] Test token extraction and storage
+- [ ] Test both completion handler and async/await variants
+
+### Integration Testing
+- [ ] Test that tokens are stored in database
+- [ ] Test that tokens are used for subsequent authenticated requests
+- [ ] Test analytics events are posted correctly
+- [ ] Test error handling and conversion
+
+### Edge Cases
+- [ ] Test with malformed response
+- [ ] Test with missing tokens in response
+- [ ] Test with null refresh token (current expected behavior)
+- [ ] Test network connectivity issues
+
+## Implementation Status: ✅ COMPLETE
+
+All required components have been implemented:
+1. ✅ Endpoint configuration
+2. ✅ Network service method
+3. ✅ Public SDK methods (both variants)
+4. ✅ Comprehensive documentation
+5. ✅ Error handling and analytics
+6. ✅ Integration with existing systems
+
+The DEI login functionality is ready for testing and integration.
