Best Practices for Close CRM Integration
Use bulk lead import API for initial data migration
Implement webhook handlers for real-time updates
Store Close lead IDs locally for efficient updates
Use custom fields strategically for integration-specific data
Implement duplicate detection before lead creation
Respect rate limits with client-side throttling
Use task API for automated follow-up creation
Leverage Close's smart views for integration-driven workflows
Security Considerations
Store API keys encrypted and never commit to repositories. Use environment variables for configuration management. Rotate API keys quarterly or when team members leave. Use HTTPS for all API communications. Implement webhook signature verification if available. Control access to integration settings through proper RBAC. Regularly audit API usage patterns for anomalies.
Ongoing Maintenance
Close's API is stable with infrequent breaking changes. Monitor Close changelog for new features and API updates. Ongoing maintenance includes monitoring webhook reliability, optimizing API usage patterns, updating custom field mappings as sales process evolves, and ensuring integration scales with growing lead volumes. Quarterly reviews ensure integration continues meeting sales team needs.
