+# 🔄 Salesforce OAuth - Backend Callback Flow Update
+
+## What Changed?
+
+The Salesforce OAuth implementation has been updated to use a **backend callback flow** instead of a mobile deep-link scheme. This means the backend server handles the OAuth callback and token exchange directly.
+
+---
+
+## Previous Flow vs New Flow
+
+### ❌ Previous Flow (Deep Link)
+```
+Salesforce → Mobile App (deep link) → Send code to backend → Backend exchanges token
+```
+- **Redirect URI**: `centralizedreportingsystem://oauth/salesforce/callback`
+- **Problem**: Custom scheme requires complex deep linking configuration
+- **Risk**: Authorization code exposed to mobile app
+
+### ✅ New Flow (Backend Callback)
+```
+Salesforce → Backend Server → Exchange token → Success page → Mobile app detects success
+```
+- **Redirect URI**: `https://YOUR_BACKEND_URL/api/v1/users/oauth/callback?user_uuid=USER_ID&service_name=salesforce`
+- **Benefits**: 
+  - Backend handles token exchange securely
+  - No need for deep linking configuration
+  - Authorization code never exposed to mobile app
+  - Standard OAuth 2.0 web flow
+
+---
+
+## Code Changes
+
+### SalesforceAuth.tsx
+
+#### 1. Updated Configuration
+```typescript
+// OLD
+const SALESFORCE_CONFIG = {
+  CLIENT_ID: 'YOUR_CLIENT_ID',
+  REDIRECT_URI: 'centralizedreportingsystem://oauth/salesforce/callback',
+  AUTH_BASE_URL: 'https://login.salesforce.com',
+};
+
+// NEW
+const SALESFORCE_CONFIG = {
+  CLIENT_ID: 'YOUR_CLIENT_ID',
+  BACKEND_BASE_URL: 'https://d5285bf63993.ngrok-free.app',
+  CALLBACK_PATH: '/api/v1/users/oauth/callback',
+  AUTH_BASE_URL: 'https://login.salesforce.com',
+};
+```
+
+#### 2. Updated OAuth URL Builder
+```typescript
+// OLD
+const buildSalesforceAuthUrl = (): string => {
+  const redirectUri = 'centralizedreportingsystem://oauth/salesforce/callback';
+  // ...
+};
+
+// NEW
+const buildSalesforceAuthUrl = (userUuid: string): string => {
+  // Build redirect URI with query parameters for backend
+  const redirectUri = `${BACKEND_BASE_URL}${CALLBACK_PATH}?user_uuid=${userUuid}&service_name=salesforce`;
+  // ...
+};
+```
+
+#### 3. New Detection Functions
+```typescript
+// Check if URL is the backend callback
+const isBackendCallbackUri = (url: string): boolean => {
+  return url.includes('/api/v1/users/oauth/callback');
+};
+
+// Check for success
+const isCallbackSuccess = (url: string): boolean => {
+  const status = getQueryParamFromUrl(url, 'status');
+  return status === 'success';
+};
+
+// Check for error
+const isCallbackError = (url: string): boolean => {
+  const status = getQueryParamFromUrl(url, 'status');
+  return status === 'error' || status === 'failure';
+};
+```
+
+#### 4. Simplified Navigation Handler
+```typescript
+// OLD - Mobile app handled token exchange
+handleNavigationStateChange = (navState) => {
+  if (isRedirectUri(url) && authCode) {
+    handleAuthorizationCode(authCode); // Send code to backend
+  }
+};
+
+// NEW - Backend handles token exchange
+handleNavigationStateChange = (navState) => {
+  if (isBackendCallbackUri(url)) {
+    if (isCallbackSuccess(url)) {
+      handleBackendSuccess(); // Just close modal
+    }
+    if (isCallbackError(url)) {
+      handleBackendError(url); // Show error
+    }
+  }
+};
+```
+
+---
+
+## Backend Implementation Required
+
+### Endpoint: `GET /api/v1/users/oauth/callback`
+
+Your backend **must** implement this endpoint to handle the OAuth callback from Salesforce.
+
+#### Query Parameters (Received from Salesforce):
+```typescript
+{
+  user_uuid: string;        // User ID (passed in redirect_uri)
+  service_name: string;     // 'salesforce' (passed in redirect_uri)
+  code: string;             // Authorization code from Salesforce
+}
+```
+
+#### Backend Responsibilities:
+
+1. **Receive the callback** from Salesforce
+2. **Extract** query parameters: `user_uuid`, `service_name`, `code`
+3. **Exchange** authorization code for tokens with Salesforce:
+   ```http
+   POST https://login.salesforce.com/services/oauth2/token
+     grant_type=authorization_code
+     code={CODE}
+     client_id={CLIENT_ID}
+     client_secret={CLIENT_SECRET}
+     redirect_uri={CALLBACK_URL_WITH_PARAMS}
+   ```
+4. **Store** tokens (encrypted) in database
+5. **Return** success/error HTML page:
+   - Success: Redirect to `?status=success`
+   - Error: Redirect to `?status=error&message=ERROR_MESSAGE`
+
+#### Example Response (Success):
+```html
+<!DOCTYPE html>
+<html>
+<head><title>Success</title></head>
+<body>
+  <h1>✓ Authentication Successful!</h1>
+  <p>Your Salesforce account has been connected.</p>
+  <script>
+    // Mobile app will detect this URL
+    window.location.search = '?status=success';
+  </script>
+</body>
+</html>
+```
+
+See [SALESFORCE_BACKEND_CALLBACK_FLOW.md](src/modules/integrations/screens/SALESFORCE_BACKEND_CALLBACK_FLOW.md) for complete backend implementation guide.
+
+---
+
+## Configuration Steps
+
+### 1. Update Salesforce Connected App
+
+In your Salesforce Connected App settings:
+
+**Old Callback URL**:
+```
+centralizedreportingsystem://oauth/salesforce/callback
+```
+
+**New Callback URL**:
+```
+https://YOUR_BACKEND_URL/api/v1/users/oauth/callback
+```
+
+> Note: Don't include query parameters in the Salesforce Connected App config. The app adds them dynamically.
+
+### 2. Update Mobile App (Already Done ✅)
+
+The `SalesforceAuth.tsx` component has been updated with:
+- ✅ New backend callback URL configuration
+- ✅ Detection logic for backend callback
+- ✅ Success/error handling
+- ✅ User UUID passed to backend
+
+### 3. Configure Backend
+
+Update your environment variables:
+
+```bash
+# .env
+SALESFORCE_CLIENT_ID=3MVG9GBhY6wQjl2sueQtv2NXMm3EuWtEvOQoeKRAzYcgs2...
+SALESFORCE_CLIENT_SECRET=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+BACKEND_URL=https://d5285bf63993.ngrok-free.app
+ENCRYPTION_KEY=0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef
+```
+
+### 4. Implement Backend Endpoint
+
+Create the `/api/v1/users/oauth/callback` endpoint following the guide in [SALESFORCE_BACKEND_CALLBACK_FLOW.md](src/modules/integrations/screens/SALESFORCE_BACKEND_CALLBACK_FLOW.md).
+
+---
+
+## Testing the Updated Flow
+
+### Test Checklist:
+
+1. **Start Backend Server**
+   - Ensure backend is running
+   - Verify callback endpoint is accessible
+   - For local testing, use ngrok: `ngrok http 4000`
+
+2. **Update Configuration**
+   - Update `BACKEND_BASE_URL` in `SalesforceAuth.tsx`
+   - Update Salesforce Connected App callback URL
+   - Restart mobile app
+
+3. **Test Authentication**
+   - Open app → CRM & Sales → Salesforce
+   - Complete Salesforce login
+   - **Expected**: Redirect to backend URL
+   - **Backend logs should show**: "Received callback", "Token exchange successful", "Tokens stored"
+   - **Mobile app should show**: Success message, then close modal
+
+4. **Verify Token Storage**
+   - Check database for stored tokens
+   - Verify tokens are encrypted
+   - Verify associated with correct user_id
+
+5. **Test Re-authentication**
+   - Tap "Re-auth" button
+   - Complete flow again
+   - Verify tokens are updated in database
+
+---
+
+## Debugging
+
+### Check Logs
+
+#### Mobile App (React Native)
+```
+[SalesforceAuth] Built OAuth URL: https://login.salesforce.com/...
+[SalesforceAuth] Redirect URI: https://YOUR_BACKEND/callback?user_uuid=...
+[SalesforceAuth] Backend callback detected
+[SalesforceAuth] Backend callback indicates success
+```
+
+#### Backend Server
+```
+[OAuth Callback] Received: { user_uuid: '...', service_name: 'salesforce', hasCode: true }
+[OAuth Callback] Token exchange successful
+[OAuth Callback] Tokens stored successfully
+```
+
+### Common Issues
+
+| Issue | Solution |
+|-------|----------|
+| Backend not reachable | Use ngrok for local testing: `ngrok http 4000` |
+| Callback URL mismatch | Update Salesforce Connected App with exact backend URL |
+| Token exchange fails | Verify CLIENT_SECRET is correct in backend |
+| Mobile app doesn't detect success | Ensure backend returns HTML with `?status=success` |
+
+---
+
+## Benefits of Backend Callback Flow
+
+✅ **More Secure**: Authorization code never exposed to mobile app  
+✅ **Simpler Configuration**: No deep linking setup needed  
+✅ **Standard OAuth**: Follows standard web OAuth 2.0 flow  
+✅ **Backend Control**: Full control over token exchange and storage  
+✅ **Better Error Handling**: Backend can provide detailed error messages  
+✅ **Token Refresh**: Backend can implement automatic token refresh

+
+---
+
+## 🔧 Configuration Required
+
+### Step 1: Create Salesforce Connected App
+
+1. **Access Salesforce Setup**
+   - Log in to Salesforce (Production or Sandbox)
+   - Click gear icon (⚙️) → Setup
+
+2. **Create Connected App**
+   - Navigate to App Manager
+   - Click "New Connected App"
+   - Fill in basic information:
+     - **Name**: `Centralized Reporting System`
+     - **Contact Email**: Your email
+
+3. **Enable OAuth Settings**
+   - Check "Enable OAuth Settings"
+   - **Callback URL**: `centralizedreportingsystem://oauth/salesforce/callback`
+   - **Select OAuth Scopes**:
+     - Access the identity URL service (id, profile, email, address, phone)
+     - Access unique user identifiers (openid)
+     - Perform requests at any time (refresh_token, offline_access)
+     - Manage user data via APIs (api)
+
+4. **Save and Retrieve Credentials**
+   - Wait 2-10 minutes for processing
+   - Navigate back to App Manager → View your app
+   - Copy the **Consumer Key** (Client ID)
+   - Reveal and copy the **Consumer Secret** (Client Secret)
+
+### Step 2: Update Application Configuration
+
+Open `src/modules/integrations/screens/SalesforceAuth.tsx` and update:
+
+```typescript
+const SALESFORCE_CONFIG = {
+  // ⚠️ REPLACE with your Consumer Key from Salesforce
+  CLIENT_ID: 'YOUR_CONSUMER_KEY_HERE',
+  
+  // This must match exactly what you configured in Salesforce
+  REDIRECT_URI: 'centralizedreportingsystem://oauth/salesforce/callback',
+  
+  // Production: https://login.salesforce.com
+  // Sandbox: https://test.salesforce.com
+  AUTH_BASE_URL: 'https://login.salesforce.com',
+  
+  RESPONSE_TYPE: 'code',
+  DISPLAY: 'touch',
+};
+```
+
+### Step 3: Backend Token Exchange
+
+Your backend needs to implement the token exchange endpoint:
+
+**Endpoint**: `POST /api/v1/integrations/manage-token`
+
+**Request Body**:
+```json
+{
+  "authorization_code": "aPrxXXXXXXXXX",
+  "id": "user-uuid",
+  "service_name": "salesforce",
+  "access_token": "user-session-token"
+}
+```
+
+**Backend Should**:
+1. Receive the authorization code
+2. Exchange it with Salesforce for an access token:
+   ```http
+   POST https://login.salesforce.com/services/oauth2/token
+   Content-Type: application/x-www-form-urlencoded
+
+   grant_type=authorization_code
+   &code={AUTH_CODE}
+   &client_id={CLIENT_ID}
+   &client_secret={CLIENT_SECRET}
+   &redirect_uri={REDIRECT_URI}
+   ```
+3. Store tokens securely (encrypted)
+4. Return success/failure response
+
+**Salesforce Response**:
+```json
+{
+  "access_token": "00D...ABC",
+  "refresh_token": "5Aep...XYZ",
+  "instance_url": "https://yourinstance.salesforce.com",
+  "id": "https://login.salesforce.com/id/00D.../005...",
+  "token_type": "Bearer",
+  "issued_at": "1699999999999"
+}
+```
+
+### Step 4: Optional - Data Sync Endpoint
+
+If you want to sync Salesforce data, implement:
+
+**Endpoint**: `POST /api/v1/integrations/salesforce/sync/schedule`
+
+This is called automatically after successful authentication to initiate data synchronization.
+
+---
+
+## 🚀 How to Use
+
+### For End Users:
+
+1. **Navigate to Integration**
+   - Open app → Integrations tab
+   - Tap "CRM & Sales Integration"
+
+2. **Select Salesforce**
+   - Tap on "Salesforce" service
+   - If not authenticated, Salesforce login screen will appear
+
+3. **Authenticate**
+   - Enter Salesforce credentials
+   - Complete 2FA if enabled
+   - Approve OAuth permissions
+
+4. **Success**
+   - Authorization code is captured
+   - Backend exchanges code for tokens
+   - Processing modal shows progress
+   - Modal closes automatically on success
+
+5. **Re-authenticate (Optional)**
+   - Tap the "Re-auth" button next to Salesforce
+   - Useful for changing organizations or refreshing permissions

+```
+
+---
+
+## 🔒 Security Considerations
+
+1. **Never Commit Credentials**
+   - Store Client ID and Secret in environment variables
+   - Use `.env` files (don't commit to Git)
+   - Example:
+     ```bash
+     # .env
+     SALESFORCE_CLIENT_ID=your_consumer_key
+     SALESFORCE_CLIENT_SECRET=your_consumer_secret
+     ```
+
+2. **Backend Token Storage**
+   - Encrypt tokens before storing
+   - Use secure database encryption
+   - Implement token rotation
+
+3. **HTTPS Only**
+   - Always use `https://` for Salesforce APIs
+   - Never downgrade to HTTP in production
+
+4. **Minimal Scopes**
+   - Request only necessary OAuth scopes
+   - Avoid `full` access unless required
+
+5. **State Parameter** (Future Enhancement)
+   - Consider adding CSRF protection with state parameter
+   - Validate state on callback
+
+---

+## Redux State Management
+
+### State Structure
+```typescript
+{
+  events: SalesforceEvent[];
+  leads: SalesforceLead[];
+  tasks: SalesforceTask[];
+  accounts: SalesforceAccount[];
+  opportunities: SalesforceOpportunity[];
+  loading: { /* loading states for each type */ };
+  errors: { /* error states for each type */ };
+  pagination: { /* pagination info for each type */ };
+  counts: { /* total counts from API */ };
+  lastUpdated: { /* last updated timestamps */ };
+}
+```
+
+### Actions
+- `fetchAllSalesforceCrmData()` - Fetch all data types in parallel
+- `fetchSalesforceEvents()` - Fetch events with pagination
+- `fetchSalesforceLeads()` - Fetch leads with pagination
+- `fetchSalesforceTasks()` - Fetch tasks with pagination
+- `fetchSalesforceAccounts()` - Fetch accounts with pagination
+- `fetchSalesforceOpportunities()` - Fetch opportunities with pagination
+- `fetchSalesforceCrmCounts()` - Fetch total counts for all types
+- `resetEventsPagination()` - Reset events pagination
+- `resetLeadsPagination()` - Reset leads pagination
+- `resetTasksPagination()` - Reset tasks pagination
+- `resetAccountsPagination()` - Reset accounts pagination
+- `resetOpportunitiesPagination()` - Reset opportunities pagination
+- `clearData()` - Clear all data
+- `clearErrors()` - Clear all errors
+
+### Selectors
+- `selectSalesforceEvents` - Get events array
+- `selectSalesforceLeads` - Get leads array
+- `selectSalesforceTasks` - Get tasks array
+- `selectSalesforceAccounts` - Get accounts array
+- `selectSalesforceOpportunities` - Get opportunities array
+- `selectSalesforceCrmLoading` - Get loading states
+- `selectSalesforceCrmErrors` - Get error states
+- `selectSalesforceCrmCounts` - Get total counts
+- `selectDashboardData` - Get computed dashboard data with summary
+- `selectIsAnyLoading` - Check if any data is loading
+- `selectHasAnyError` - Check if any errors exist
+
+## Navigation
+
+The module is integrated into the CRM navigator:
+
+```typescript
+<Stack.Screen 
+  name="SalesforceDashboard" 
+  component={SalesforceCrmDashboardScreen} 
+  options={{headerShown:false}} 
+/>
+<Stack.Screen 
+  name="SalesforceData" 
+  component={SalesforceDataScreen} 
+  options={{headerShown:false}} 
+/>
+```
+
+## Usage
+
+### Navigate to Salesforce Dashboard
+```typescript
+navigation.navigate('SalesforceDashboard');
+```
+
+### Navigate to Salesforce Data Screen
+```typescript
+navigation.navigate('SalesforceData');
+```
+
+### Fetch Salesforce Data
+```typescript
+import { useDispatch } from 'react-redux';
+import { fetchAllSalesforceCrmData } from '@/modules/crm/salesforce';
+
+const dispatch = useDispatch();
+
+// Fetch all data
+await dispatch(fetchAllSalesforceCrmData()).unwrap();
+
+// Fetch specific data type with pagination
+await dispatch(fetchSalesforceLeads({ page: 1, limit: 20 })).unwrap();
+```
+
+### Access Salesforce Data
+```typescript
+import { useSelector } from 'react-redux';
+import { selectSalesforceLeads, selectDashboardData } from '@/modules/crm/salesforce';
+
+// Get leads
+const leads = useSelector(selectSalesforceLeads);
+
+// Get dashboard data with computed summaries
+const dashboardData = useSelector(selectDashboardData);
+```
+
+## API Response Format
+
+All endpoints return responses in the following format:
+
+```json
+{
+  "status": "success",
+  "message": "Salesforce crm {resource} data fetched successfully",
+  "data": {
+    "success": true,
+    "data": [ /* array of records */ ],
+    "count": 56,
+    "metadata": {
+      "totalSize": 56,
+      "done": true,
+      "nextRecordsUrl": null
+    }
+  },
+  "timestamp": "2025-10-09T06:40:31.428Z"
+}
+```
+
+## Styling
+
+The module follows the application's design system:
+- Uses theme colors from `useTheme()` hook
+- Consistent spacing and typography
+- Responsive layouts
+- Material Community Icons
+- Smooth animations and transitions
+
+## Data Persistence
+
+The Salesforce CRM state is persisted using Redux Persist:
+- State is saved to AsyncStorage
+- Survives app restarts
+- Automatically rehydrated on app launch
+
+## Error Handling
+
+- All API calls wrapped in try-catch blocks
+- Error states stored in Redux
+- User-friendly error messages via Toast notifications
+- Retry functionality on error screens
+- Loading states for all async operations
+
+## Performance Optimizations
+
+- **Parallel Data Fetching**: All data types fetched simultaneously
+- **Infinite Scrolling**: Load data in chunks to reduce initial load time
+- **Memoized Selectors**: Prevent unnecessary re-renders
+- **Redux Persist**: Cache data locally to reduce API calls
+- **Pull-to-refresh**: Manual refresh when needed
+- **Optimized Re-renders**: Use React.memo where appropriate
+
+## Future Enhancements
+
+- Advanced filtering options
+- Search functionality
+- Sort options for each data type
+- Export data to CSV/Excel
+- Detailed view screens for each record
+- Create/Edit/Delete operations
+- Real-time sync with Salesforce
+- Offline mode support
+- Analytics and reporting
+- Custom dashboard widgets

+
+## Backend Implementation
+
+### Endpoint: `GET /api/v1/users/oauth/callback`
+
+#### Query Parameters (Received from Salesforce)
+```typescript
+{
+  user_uuid: string;        // User ID passed in redirect_uri
+  service_name: string;     // 'salesforce' passed in redirect_uri
+  code: string;             // Authorization code from Salesforce
+  state?: string;           // Optional CSRF token
+}
+```
+
+#### Implementation Steps
+
+##### 1. Extract Query Parameters
+```javascript
+const { code: authorization_code, user_uuid, service_name } = req.query;
+
+// Validate required parameters
+if (!authorization_code || !user_uuid || !service_name) {
+  return res.redirect(`/oauth/error?message=Missing required parameters`);
+}
+
+// Verify service_name is 'salesforce'
+if (service_name !== 'salesforce') {
+  return res.redirect(`/oauth/error?message=Invalid service name`);
+}
+```
+
+##### 2. Exchange Authorization Code for Tokens
+```javascript
+const axios = require('axios');
+
+try {
+  const tokenResponse = await axios.post(
+    'https://login.salesforce.com/services/oauth2/token',
+    null,
+    {
+      params: {
+        grant_type: 'authorization_code',
+        code: authorization_code,
+        client_id: process.env.SALESFORCE_CLIENT_ID,
+        client_secret: process.env.SALESFORCE_CLIENT_SECRET,
+        redirect_uri: `${process.env.BACKEND_URL}/api/v1/users/oauth/callback?user_uuid=${user_uuid}&service_name=salesforce`
+      },
+      headers: {
+        'Content-Type': 'application/x-www-form-urlencoded'
+      }
+    }
+  );
+
+  const {
+    access_token,
+    refresh_token,
+    instance_url,
+    id,
+    issued_at,
+    signature
+  } = tokenResponse.data;
+
+  // Store tokens...
+  
+} catch (error) {
+  console.error('Token exchange failed:', error);
+  return res.redirect(`/oauth/error?message=${encodeURIComponent(error.message)}`);
+}
+```
+
+##### 3. Store Tokens Securely
+```javascript
+// Encrypt tokens before storing
+const encryptedAccessToken = encrypt(access_token);
+const encryptedRefreshToken = encrypt(refresh_token);
+
+await db.integrations.upsert({
+  where: {
+    user_id: user_uuid,
+    service_name: 'salesforce'
+  },
+  update: {
+    access_token: encryptedAccessToken,
+    refresh_token: encryptedRefreshToken,
+    instance_url: instance_url,
+    token_issued_at: new Date(parseInt(issued_at)),
+    updated_at: new Date()
+  },
+  create: {
+    user_id: user_uuid,
+    service_name: 'salesforce',
+    access_token: encryptedAccessToken,
+    refresh_token: encryptedRefreshToken,
+    instance_url: instance_url,
+    token_issued_at: new Date(parseInt(issued_at)),
+    created_at: new Date()
+  }
+});
+```
+
+##### 4. Return Success Response
+```javascript
+// Option 1: Redirect to success page with status
+res.redirect('/oauth/success?status=success&service=salesforce');
+
+// Option 2: Return HTML page that mobile app can detect
+res.send(`
+  <!DOCTYPE html>
+  <html>
+  <head>
+    <title>Authentication Successful</title>
+    <meta name="viewport" content="width=device-width, initial-scale=1.0">

+  </head>
+  <body>
+    <div class="container">
+      <div class="success-icon">✓</div>

+      window.location.search = '?status=success';
+    </script>
+  </body>
+  </html>
+`);
+```
+
+##### 5. Handle Errors
+```javascript
+// If token exchange or storage fails
+res.send(`
+  <!DOCTYPE html>
+  <html>
+  <head>
+    <title>Authentication Failed</title>
+    <meta name="viewport" content="width=device-width, initial-scale=1.0">

+      }
+      .container {
+        text-align: center;
+        background: white;
+        padding: 40px;
+        border-radius: 12px;
+        box-shadow: 0 10px 40px rgba(0,0,0,0.2);
+      }
+      .error-icon {
+        font-size: 64px;
+        color: #ef4444;
+        margin-bottom: 20px;
+      }
+      h1 {
+        color: #1f2937;
+        margin-bottom: 10px;
+      }
+      p {

+    </style>
+  </head>
+  <body>
+    <div class="container">
+      <div class="error-icon">✗</div>
+      <h1>Authentication Failed</h1>
+      <p>${errorMessage || 'An error occurred during authentication.'}</p>
+      <p>Please try again.</p>
+    </div>
+    <script>
+      window.location.search = '?status=error&message=${encodeURIComponent(errorMessage)}';
+    </script>
+  </body>
+  </html>
+`);
+```
+
+---
+
+## Mobile App Detection Logic
+
+The mobile app (SalesforceAuth component) detects the backend callback using these helper functions:
+
+### Detection Functions
+```typescript
+// Check if URL is the backend callback URI
+const isBackendCallbackUri = (url: string): boolean => {
+  return url.includes('/api/v1/users/oauth/callback');
+};
+
+// Check if backend callback indicates success
+const isCallbackSuccess = (url: string): boolean => {
+  const status = getQueryParamFromUrl(url, 'status');
+  const success = getQueryParamFromUrl(url, 'success');
+  return status === 'success' || success === 'true';
+};
+
+// Check if backend callback indicates error
+const isCallbackError = (url: string): boolean => {
+  const status = getQueryParamFromUrl(url, 'status');
+  const error = getQueryParamFromUrl(url, 'error');
+  return status === 'error' || status === 'failure' || !!error;
+};
+```
+
+### Navigation State Handler
+```typescript
+handleNavigationStateChange = (navState) => {
+  const { url, loading } = navState;
+  
+  // Check if this is the backend callback URL
+  if (isBackendCallbackUri(url)) {
+    console.log('Backend callback detected');
+    
+    // Show processing modal
+    setState({ processing: true, processingStep: 'Processing...' });
+    
+    // Check for success
+    if (isCallbackSuccess(url)) {
+      handleBackendSuccess();
+      return;
+    }
+    
+    // Check for error
+    if (isCallbackError(url)) {
+      const errorMessage = getQueryParamFromUrl(url, 'message') || 'Authentication failed';
+      handleBackendError(errorMessage);
+      return;
+    }
+  }
+};
+```
+

+
+## Complete Backend Example (Node.js/Express)
+
+```javascript
+const express = require('express');
+const axios = require('axios');

+  const key = Buffer.from(process.env.ENCRYPTION_KEY, 'hex');
+  const iv = crypto.randomBytes(16);
+  
+  const cipher = crypto.createCipheriv(algorithm, key, iv);
+  let encrypted = cipher.update(text, 'utf8', 'hex');
+  encrypted += cipher.final('hex');
+  
+  const authTag = cipher.getAuthTag();
+  
+  return `${iv.toString('hex')}:${authTag.toString('hex')}:${encrypted}`;
+}

+
+## Configuration Checklist
+
+### Salesforce Connected App
+- ✅ Callback URL: `https://YOUR_BACKEND_URL/api/v1/users/oauth/callback`
+- ✅ OAuth Scopes: api, refresh_token, offline_access, profile, email, address, phone
+
+### Mobile App (SalesforceAuth.tsx)
+- ✅ `BACKEND_BASE_URL`: Your backend domain
+- ✅ `CALLBACK_PATH`: `/api/v1/users/oauth/callback`
+- ✅ `CLIENT_ID`: Salesforce Consumer Key
+
+### Backend Environment Variables
+- ✅ `SALESFORCE_CLIENT_ID`: Consumer Key from Salesforce
+- ✅ `SALESFORCE_CLIENT_SECRET`: Consumer Secret from Salesforce
+- ✅ `BACKEND_URL`: Your public backend URL
+- ✅ `ENCRYPTION_KEY`: 32-byte hex string for token encryption
+
+---
+
+## Testing
+
+1. **Test OAuth Flow**:
+   - Open app → CRM & Sales → Salesforce
+   - Complete Salesforce login
+   - Verify redirect to backend callback
+   - Check backend logs for token exchange
+   - Verify success page appears
+   - Confirm modal closes automatically
+
+2. **Test Error Handling**:
+   - Simulate invalid credentials
+   - Simulate network failure
+   - Verify error page displays
+   - Confirm retry functionality works
+
+3. **Verify Token Storage**:
+   - Check database for encrypted tokens
+   - Verify user_id association
+   - Confirm refresh_token is stored
+
+---
+
+## Security Considerations
+
+1. **HTTPS Only**: Always use HTTPS for callback URLs
+2. **Token Encryption**: Encrypt tokens before storing in database
+3. **Client Secret**: Never expose client secret to mobile app
+4. **State Parameter**: Add CSRF protection using state parameter
+5. **Token Expiration**: Implement token refresh logic
+6. **Access Control**: Validate user_uuid belongs to authenticated session
+
+---
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| Callback URL mismatch | Ensure Salesforce Connected App callback URL exactly matches backend URL with query params |
+| Token exchange fails | Check client_id and client_secret are correct |
+| Authorization code expired | Codes expire in 15 minutes - ensure timely exchange |
+| Backend not reachable | Verify backend URL is publicly accessible (use ngrok for local testing) |
+| WebView doesn't detect success | Ensure backend returns HTML with `?status=success` in URL |

+   - Access the identity URL service (id, profile, email, address, phone)
+   - Access unique user identifiers (openid)
+   - Perform requests at any time (refresh_token, offline_access)
+   - Manage user data via APIs (api)
+   - Full access to all data (full) - Optional, use with caution
+
+4. **Additional OAuth Settings**:
+   - ✅ **Enable for Device Flow**: Check this if you want to support device authentication
+   - ✅ **Require Secret for Web Server Flow**: Recommended for security
+   - ✅ **Require Secret for Refresh Token Flow**: Recommended for security
+   - ✅ **Enable Authorization Code and Credentials Flow**: Check this
+
+5. Click **Save** button
+
+### Step 5: Wait for Salesforce Processing
+After saving, Salesforce will process your app (usually 2-10 minutes).
+
+### Step 6: Retrieve OAuth Credentials
+1. Once processing is complete, navigate back to **App Manager**
+2. Find your Connected App and click the dropdown arrow (▼)
+3. Select **View**
+4. In the "API (Enable OAuth Settings)" section, you'll see:
+   - **Consumer Key** (Client ID)
+   - **Consumer Secret** (Client Secret) - Click "Click to reveal"
+
+> ⚠️ **Important**: Keep these credentials secure! Never commit them to public repositories.

+## Configure OAuth Settings
+
+### Environment-Specific Endpoints
+
+#### Production
+```
+Auth Base URL: https://login.salesforce.com
+```
+
+#### Sandbox
+```
+Auth Base URL: https://test.salesforce.com
+```
+
+### OAuth Scopes Explained
+
+| Scope | Description |
+|-------|-------------|
+| `api` | Access to all standard Salesforce REST APIs |
+| `refresh_token` | Ability to refresh the access token |
+| `offline_access` | Perform requests even when the user is offline |
+| `id` | Access to the unique identifier for the user |
+| `profile` | Access to user's profile information |
+| `email` | Access to user's email address |
+| `address` | Access to user's address |
+| `phone` | Access to user's phone number |
+| `openid` | OpenID Connect authentication |
+
+---
+
+## Update Application Configuration
+
+### Step 1: Update SalesforceAuth.tsx
+
+Open `src/modules/integrations/screens/SalesforceAuth.tsx` and update the following:
+
+```typescript
+const SALESFORCE_CONFIG = {
+  // Replace with your Consumer Key (Client ID) from Salesforce
+  CLIENT_ID: '3MVG9XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
+  
+  // This must match exactly what you configured in Salesforce Connected App
+  REDIRECT_URI: 'centralizedreportingsystem://oauth/salesforce/callback',
+  
+  // Use login.salesforce.com for production
+  // Use test.salesforce.com for sandbox
+  AUTH_BASE_URL: 'https://login.salesforce.com',
+  
+  RESPONSE_TYPE: 'code',
+  DISPLAY: 'touch', // Optimized for mobile
+};
+```
+
+### Step 2: Configure Deep Linking (Android)
+
+#### Android - Update AndroidManifest.xml
+Add the intent filter to handle the OAuth callback:
+
+```xml
+<!-- android/app/src/main/AndroidManifest.xml -->
+<activity
+  android:name=".MainActivity"
+  android:label="@string/app_name"
+  android:launchMode="singleTask">
+  
+  <!-- Existing intent filters -->
+  <intent-filter>
+    <action android:name="android.intent.action.MAIN" />
+    <category android:name="android.intent.category.LAUNCHER" />
+  </intent-filter>
+  
+  <!-- Salesforce OAuth Callback -->
+  <intent-filter>
+    <action android:name="android.intent.action.VIEW" />
+    <category android:name="android.intent.category.DEFAULT" />
+    <category android:name="android.intent.category.BROWSABLE" />
+    <data
+      android:scheme="centralizedreportingsystem"
+      android:host="oauth"
+      android:pathPrefix="/salesforce/callback" />
+  </intent-filter>
+</activity>
+```
+
+### Step 3: Configure Deep Linking (iOS)
+
+#### iOS - Update Info.plist
+Add URL types for the OAuth callback:
+
+```xml
+<!-- ios/CentralizedReportingSystem/Info.plist -->
+<key>CFBundleURLTypes</key>
+<array>
+  <dict>
+    <key>CFBundleURLSchemes</key>
+    <array>
+      <string>centralizedreportingsystem</string>
+    </array>
+    <key>CFBundleURLName</key>
+    <string>com.yourcompany.centralizedreportingsystem</string>
+  </dict>
+</array>
+```
+
+### Step 4: Backend Token Exchange Endpoint
+
+Your backend should have an endpoint to exchange the authorization code for an access token:
+
+```typescript
+// Example backend endpoint
+POST /api/v1/integrations/manage-token
+
+Request Body:
+{
+  "authorization_code": "aPrxXXXXXXXXXXXXXXXXXXXXXXXXX",
+  "id": "user-uuid",
+  "service_name": "salesforce",
+  "access_token": "user-session-token"
+}
+```
+
+The backend should:
+1. Receive the authorization code
+2. Exchange it with Salesforce for an access token
+3. Store the tokens securely (encrypted)
+4. Return success/failure response
+
+#### Salesforce Token Exchange Request
+
+Your backend should make this request to Salesforce:
+
+```http
+POST https://login.salesforce.com/services/oauth2/token
+Content-Type: application/x-www-form-urlencoded
+
+grant_type=authorization_code
+&code={AUTHORIZATION_CODE}
+&client_id={YOUR_CLIENT_ID}
+&client_secret={YOUR_CLIENT_SECRET}
+&redirect_uri={YOUR_REDIRECT_URI}
+```
+
+#### Expected Salesforce Response
+
+```json
+{
+  "access_token": "00D...ABC",
+  "refresh_token": "5Aep...XYZ",
+  "signature": "signature-value",
+  "scope": "api refresh_token offline_access id profile email",
+  "id_token": "eyJ...",
+  "instance_url": "https://yourinstance.salesforce.com",
+  "id": "https://login.salesforce.com/id/00D.../005...",
+  "token_type": "Bearer",
+  "issued_at": "1699999999999"
+}
+```
+
+---
+
+## Test the Integration
+
+### Testing Steps
+
+1. **Launch the App**
+   - Open your React Native application
+   - Navigate to **Integrations** > **CRM & Sales Integration**
+
+2. **Select Salesforce**
+   - Tap on the **Salesforce** option
+   - The Salesforce authentication WebView should open
+
+3. **Authenticate**
+   - Enter your Salesforce username and password
+   - If using Two-Factor Authentication, complete the verification
+   - Review and approve the OAuth permissions
+
+4. **Verify Success**
+   - The app should capture the authorization code
+   - Backend should exchange it for tokens
+   - You should see a success message
+   - The auth modal should close automatically
+
+5. **Check Data Sync** (if implemented)
+   - Navigate to the Salesforce dashboard
+   - Verify that data is being synced properly
+
+### Testing with Different Salesforce Orgs
+
+To test with different Salesforce organizations:
+1. Tap the **Re-auth** button next to Salesforce
+2. Confirm the re-authentication
+3. Log in with a different Salesforce account
+
+---
+
+## Troubleshooting
+
+### Common Issues and Solutions
+
+#### 1. **"redirect_uri_mismatch" Error**
+
+**Problem**: The redirect URI doesn't match what's configured in Salesforce.
+
+**Solution**:
+- Ensure the redirect URI in `SalesforceAuth.tsx` exactly matches what's in the Salesforce Connected App
+- Check for trailing slashes, capitalization, and special characters
+- Both values must be identical: `centralizedreportingsystem://oauth/salesforce/callback`
+
+---
+
+#### 2. **"invalid_client_id" Error**
+
+**Problem**: The Client ID is incorrect or the Connected App is not yet active.
+
+**Solution**:
+- Wait 2-10 minutes after creating the Connected App for Salesforce to process it
+- Double-check the Consumer Key (Client ID) from Salesforce matches your config
+- Ensure there are no extra spaces or characters
+
+---
+
+#### 3. **WebView Doesn't Load**
+
+**Problem**: The Salesforce login page doesn't appear.
+
+**Solution**:
+- Check your internet connection
+- Verify the `AUTH_BASE_URL` is correct (login.salesforce.com or test.salesforce.com)
+- Check console logs for error messages
+- Ensure WebView has internet permission (Android)
+
+---
+
+#### 4. **App Doesn't Capture the Code**
+
+**Problem**: After authentication, the app doesn't proceed.
+
+**Solution**:
+- Verify deep linking is configured correctly for both iOS and Android
+- Check that the redirect URI scheme matches your app's URL scheme
+- Test the deep link manually using ADB (Android) or xcrun (iOS)
+- Check console logs for navigation state changes
+
+---
+
+#### 5. **"access_denied" Error**
+
+**Problem**: User denied the OAuth permissions.
+
+**Solution**:
+- User must approve all requested permissions
+- If permissions are too broad, consider reducing the requested scopes
+- Check if the Connected App is enabled for the user's profile
+
+---
+
+#### 6. **Token Exchange Fails**
+
+**Problem**: Backend returns an error when exchanging the authorization code.
+
+**Solution**:
+- Verify backend endpoint is working: `/api/v1/integrations/manage-token`
+- Check that the backend has the correct Consumer Secret
+- Authorization codes expire after 15 minutes - ensure timely exchange
+- Check backend logs for detailed error messages
+- Verify the authorization code is being sent correctly
+
+---
+
+#### 7. **Sandbox vs Production Confusion**
+
+**Problem**: Using the wrong Salesforce environment.
+
+**Solution**:
+- **Production**: Use `https://login.salesforce.com`
+- **Sandbox**: Use `https://test.salesforce.com`
+- Create separate Connected Apps for each environment
+- Update the config based on your current environment
+
+---
+
+### Debug Logging
+
+Enable comprehensive logging to troubleshoot issues:
+
+```typescript
+// In SalesforceAuth.tsx, check console logs for:
+console.log('[SalesforceAuth] Authorization code received:', authCode);
+console.log('[SalesforceAuth] Response from manageToken:', response);
+console.log('[SalesforceAuth] nav change url:', url, 'loading:', loading);
+```
+
+---
+
+## Security Best Practices
+
+1. **Never Store Credentials in Code**
+   - Use environment variables or secure config management
+   - Never commit `.env` files with credentials to version control
+
+2. **Use HTTPS Only**
+   - Always use `https://` for Salesforce endpoints
+   - Never use `http://` in production
+
+3. **Implement Token Refresh**
+   - Store refresh tokens securely
+   - Implement automatic token refresh on expiration
+   - Handle refresh token failures gracefully
+
+4. **Encrypt Stored Tokens**
+   - Use encryption for tokens stored on device
+   - Use secure storage mechanisms (Keychain, KeyStore)
+
+5. **Validate State Parameter**
+   - Include CSRF protection using state parameter
+   - Verify state on callback to prevent CSRF attacks
+
+6. **Limit OAuth Scopes**
+   - Request only the minimum scopes needed
+   - Avoid using `full` scope unless absolutely necessary
+
+7. **Monitor Token Usage**
+   - Log token usage and refresh patterns
+   - Set up alerts for unusual authentication patterns
