📔 Objective

In PR #6650 we added caching to the event integration configurations. However, @withinfocus pointed out that we were now injecting the cache directly into our controllers and it would be better to follow the CQRS pattern and move these into commands / queries. That work felt a bit large for another commit on the existing PR, so I've put all of that refactor here.

The DI piece is a bit tricky for these. Since they are dependent on the named extended cache, they can't be instantiated with the rest of the OrganizationFeatures pieces. Instead, this PR creates EventIntegrationsServiceCollectionExtensions (and associated tests) to create a clean way for Startup in API to get them into the service collection cleanly. This extension will be a landing place for more of the custom event integration methods in ServiceCollectionExtensions in future PRs. It will be a big help to have those separated out and testable.

Finally, there's a few cleanup things that I noticed in doing this work. We were allowing someone to change the integration type when updating an integration (which would also have cache implications). Instead, I've changed it to deny an update that changes the IntegrationType (that should be a brand new integration instead). I also cleaned up how we were clearing cache when the EventType changes (which is allowed) to clear both the old and new values.

Code Review Complete ✅

I've completed a comprehensive review of this CQRS refactoring. Overall, this is excellent work that significantly improves the codebase architecture, testability, and maintainability.


🌟 Overall Rating: ⭐⭐⭐⭐⭐ EXCELLENT

This PR successfully refactors the OrganizationIntegration and OrganizationIntegrationConfiguration controllers to implement the CQRS pattern with clean separation of concerns, robust security measures, and comprehensive test coverage.


Key Strengths

1. 👍 CQRS Implementation Quality

The CQRS pattern is implemented excellently:

  • Controllers are now thin orchestrators focused solely on HTTP concerns
  • Business logic properly isolated in commands/queries
  • Clear single responsibility for each command/query
  • Consistent implementation pattern across all files

Example: OrganizationIntegrationController.cs:13-18 - Clean dependency injection of commands/queries instead of repositories and cache

2. 👍 Dependency Injection & Service Registration

EventIntegrationsServiceCollectionExtensions.cs is well-designed:

  • ✅ Proper use of TryAdd* methods for idempotency
  • ✅ Cache registered before commands that depend on it
  • ✅ Validator correctly registered as Singleton (stateless)
  • ✅ Commands/queries registered as Scoped (appropriate lifetime)
  • ✅ Comprehensive test coverage verifying registration behavior

3. 👍 Critical Cache Management Fix

The dual-cache clearing for EventType changes is correctly implemented and essential:

UpdateOrganizationIntegrationConfigurationCommand.cs:44-60:

// Clear old EventType cache
await cache.RemoveAsync(...eventType: configuration.EventType);

// Clear new EventType cache if changed
if (configuration.EventType != updatedConfiguration.EventType)
{
    await cache.RemoveAsync(...eventType: updatedConfiguration.EventType);
}

This prevents stale data in both old and new cache keys when EventType changes. Test coverage confirms both cache removals occur with correct keys.

4. 👍 Security: IntegrationType Change Prevention

UpdateOrganizationIntegrationCommand.cs:22-28:

if (integration is null ||
    integration.OrganizationId != organizationId ||
    integration.Type != updatedIntegration.Type)  // Prevents type changing
{
    throw new NotFoundException();
}

This is a critical security measure that prevents:

  • Changing integration type (e.g., Webhook → Slack)
  • Bypassing type-specific validation rules
  • Creating inconsistent data states
  • Accessing integrations from different organizations

Integration types have different configuration requirements and security implications. Excellent security consideration!

5. 👍 Validation Logic Centralization

OrganizationIntegrationConfigurationValidator.cs provides:

  • ✅ Centralized validation (moved from request model)
  • ✅ Type-safe validation using generics
  • ✅ Proper JSON deserialization with error handling
  • ✅ 244 lines of comprehensive test coverage

6. 👍 Exceptional Test Coverage

1,516 lines of new tests covering:

  • ✅ All happy paths and error scenarios
  • ✅ Authorization checks
  • ✅ Cache invalidation verification (including dual-clearing)
  • ✅ Security scenarios (type change prevention)
  • ✅ Edge cases and validation rules
  • ✅ Service registration and DI behavior

Controller tests simplified from ~800 to ~200 lines because business logic moved to commands/queries.


📝 Minor Observations

Consistency Opportunity (Not Blocking)

Most commands use primary constructors, but DeleteOrganizationIntegrationCommand uses traditional constructor with fields. Consider using primary constructors consistently for better readability.

Enhancement Opportunity (Future Work)

The validator returns only boolean results. Consider returning detailed validation errors in the future for better user feedback:

public interface IOrganizationIntegrationConfigurationValidator
{
    ValidationResult ValidateConfiguration(...);
}

Current generic error messages are acceptable for now.


Performance Impact: ✅ Positive/Neutral

  • Improved: More targeted cache invalidation with specific keys
  • Improved: Tag-based cache clearing for efficiency
  • Improved: Validator reused as singleton across requests
  • Neutral: No performance regression introduced

Security Assessment: ✅ No Issues Found

  • ✅ IntegrationType change prevention implemented correctly
  • ✅ Authorization checks maintained in controllers
  • ✅ Using NotFoundException for auth failures (prevents information disclosure)
  • ✅ No PII or sensitive data logged
  • ✅ Validation prevents injection attacks through proper JSON deserialization
  • ✅ Cache keys properly scoped to organization + integration type

Code Organization: ✅ Excellent

  • Clear feature-based directory structure under EventIntegrations/
  • Separation between domain logic and cross-cutting concerns
  • Interfaces co-located with implementations
  • Request models simplified to focus only on data binding (109 lines → 29 lines)

Verdict: ✅ APPROVED - Ready to Merge

This refactoring achieves all stated goals:

  • ✅ Cache injection moved from controllers to CQRS commands/queries
  • ✅ EventIntegrationsServiceCollectionExtensions provides clean DI setup
  • ✅ IntegrationType changes properly prevented on updates
  • ✅ Cache clearing improved for EventType changes

No functional bugs identified. No security vulnerabilities found.

The code quality is high, the CQRS pattern is properly implemented, and the test coverage is comprehensive. The security considerations around preventing IntegrationType changes are particularly noteworthy.

Great work! 🎉

Can we break this up into smaller PRs? Consider identifying logical groupings. For example, if we have a lot of code that’s just moving logic from one class to another with no real changes, then consider making a PR just for that.

@JimmyVo16 I spoke with @withinfocus and I'm going to close this PR in favor of two smaller PRs (#6689 and #6690 ). I think that will help right-size the review. 👍
