# Technical Implementation Guide

This guide provides technical details about our Salesforce NPSP integration implementation.

## Integration Architecture

Our Salesforce integration is built on a layered architecture:

1. **Base Integration Layer**
   * `CrmIntegration` base class
   * Common CRM operations
   * Authentication handling

2. **Salesforce Specific Layer**
   * `Salesforce` class extending `CrmIntegration`
   * NPSP-specific implementations
   * Custom Salesforce API handling

3. **Model Layer**
   * `SalesforceIntegration` model
   * Field mapping management
   * Integration configuration

## Core Classes

### Salesforce Integration Class

The main integration class (`App\Integrations\Salesforce`) provides:

```php theme={null}
class Salesforce extends CrmIntegration
{
    // Authentication and connection management
    protected function accessToken()
    protected function http()
    
    // Data synchronization methods
    public function pullDonors()
    public function pullCampaigns()
    public function pullTransactions()
    // ... other pull methods
    
    public function pushDonor()
    public function pushTransaction()
    public function pushCampaign()
    // ... other push methods
}
```

### Salesforce Integration Model

The `SalesforceIntegration` model (`App\Models\SalesforceIntegration`) handles:

```php theme={null}
class SalesforceIntegration extends Model
{
    // Field mapping management
    public function getContactFieldOptionsAttribute()
    public function getAccountFieldOptionsAttribute()
    public function getOpportunityFieldOptionsAttribute()
    // ... other field options
    
    // Integration configuration
    public function setupDefaultMappings()
    public function createMappingRule()
}
```

## Key Implementation Patterns

### 1. Data Synchronization

#### Pull Operations

```php theme={null}
// Example pull operation
protected function pullDonors($from = null, $to = null)
{
    // SOQL query construction
    // Data transformation
    // Model creation/update
}

// Example push operation
public function pushTransaction(Transaction $transaction)
{
    // Payload compilation
    // API call
    // Response handling
}
```

### 2. Field Mapping

Field mapping is managed through the `SalesforceIntegration` model:

```php theme={null}
// Example field options
public function getContactFieldOptionsAttribute()
{
    return $this->getFieldOptions('Contact');
}

// Mapping rule creation
public function createMappingRule($data)
{
    // Rule validation
    // Mapping creation
    // Configuration update
}
```

### 3. Data Transformation

#### Payload Compilation

```php theme={null}
// Example payload compilation
public function compileDonorPayload(Donor $donor): array
{
    // Field mapping
    // Data transformation
    // Validation
}

public function compileTransactionPayload(Transaction $transaction)
{
    // Opportunity creation
    // Payment handling
    // Allocation management
}
```

### 4. Error Handling

The integration implements comprehensive error handling:

```php theme={null}
// Example error handling
protected function handleApiError($response)
{
    // Error logging
    // Rate limit handling
    // Retry logic
}
```

## API Integration Details

### Authentication

```php theme={null}
protected function accessToken()
{
    // OAuth token management
    // Token refresh
    // Error handling
}
```

### HTTP Client

```php theme={null}
public function http()
{
    // Client configuration
    // Headers management
    // Rate limiting
}
```

## Data Models

### Core Models

1. **Donor Model**
   * Maps to Salesforce Contact
   * Handles individual and organizational donors
   * Supports merge operations

2. **Transaction Model**
   * Maps to Salesforce Opportunity
   * Includes payment information
   * Supports allocations

3. **Campaign Model**
   * Maps to Salesforce Campaign
   * Manages campaign members
   * Supports events and fundraisers

### Supporting Models

1. **ScheduledDonation**
   * Maps to Recurring Donation
   * Payment schedule management

2. **Pledge**
   * Maps to NPSP Pledge
   * Commitment tracking

3. **SoftCredit**
   * Influence tracking
   * Attribution management

## Best Practices

### 1. API Usage

* Implement proper rate limiting
* Use batch operations when possible
* Handle API errors gracefully
* Monitor API call limits

### 2. Data Management

* Use provided sync methods
* Follow field mapping conventions
* Implement proper validation
* Handle merges correctly

### 3. Performance

* Implement caching where appropriate
* Use batch operations
* Monitor API call patterns
* Optimize query patterns

### 4. Security

* Secure token management
* Proper error handling
* Data validation
* Access control

## Troubleshooting

### Common Issues

1. **API Rate Limits**
   * Monitor API call patterns
   * Implement proper retry logic
   * Use batch operations

2. **Data Synchronization**
   * Check field mappings
   * Verify data transformation
   * Monitor sync logs

3. **Authentication**
   * Token refresh handling
   * Connection management
   * Error recovery

### Debugging

1. **Logging**
   * Integration logs
   * API call tracking
   * Error monitoring

2. **Monitoring**
   * Performance metrics
   * API usage
   * Sync status

## Development Guidelines

1. **Code Structure**
   * Follow existing patterns
   * Maintain separation of concerns
   * Document new features

2. **Testing**
   * Unit test new features
   * Integration testing
   * API mocking

3. **Documentation**
   * Update field mappings
   * Document new features
   * Maintain technical docs
