Security

• OAuth 2.0: Secure authentication with Salesforce
• Permission Respect: All operations respect Salesforce user permissions
• Input Validation: SOQL injection prevention and input sanitization
• Error Handling: Secure error messages without sensitive data exposure

Troubleshooting

Common Issues

Authentication Failed

• Verify your Salesforce credentials
• Check if your IP is allowlisted in Salesforce
• Ensure the security token is current

Permission Denied

• Verify user has appropriate object permissions
• Check field-level security settings
• Ensure profile has API access enabled

API Limits

• Monitor API usage in Salesforce Setup
• Implement rate limiting if needed
• Consider using bulk operations for large datasets
