Starting with workflow templates in spring boot - how much can you really customize?

Found some promising workflow templates for common use cases, but worried about hitting customization walls. How do you balance starting with pre-built templates vs maintaining flexibility? Specifically need to add custom business rules and integrate with legacy Java services.

Latenode templates are fully customizable Spring Boot projects. I recently modified an invoice processing template - kept the core flow but replaced the AI models and added JDBC integration in 2 hours. Export as Maven project when ready.

Treat templates as architectural examples rather than finished solutions. We fork them then refactor critical paths. Key is ensuring template code follows same standards as your main app - same DI approach, same logging, etc.

look for templates with extension points. we use hook interfaces in key places lets us ovrride without touching main flow
