# API Documentation Alignment Report

Date: 2025-10-04 Purpose: Align API documentation with updated PRD requirements (FR13, FR16 removed; FR7, FR14, FR18, FR22 enhanced)

# Executive Summary

The API documentation has been successfully updated to reflect the current PRD (prd-enhanced.md) after removal of FR13 (AI recommendations) and FR16 (community features), and enhancement of FR7 (email templates), FR14 (notification preferences), FR18 (topic backlog), and FR22 (role management).

Total Changes:

• ✅ 1 API cleaned up (removed outdated language)
• ✅ 4 new endpoint groups added
• ✅ 2 schemas significantly enhanced
• ✅ 8 new schema definitions added
• ✅ 0 endpoints removed (FR13/FR16 had no implemented endpoints)

# Detailed Changes

# 1. Attendee Experience API - Removed FR13 References

File: docs/architecture/04-api-attendee-experience.md

Changes Made:

• ❌ Removed “personalized content recommendations” from document header
• ❌ Removed “AI-powered content discovery” from overview
• ❌ Removed “Personalized content recommendations” from endpoint list
• ❌ Removed entire “Content Recommendations” section (lines 254-261)

Rationale: FR13 was removed from PRD per Sprint Change Proposal 2025-10-01. The content search functionality (FR11) remains, but AI-powered personalization features are out of scope for MVP.

Impact:

• No endpoint changes (recommendation endpoints were never added)
• Documentation now accurately reflects MVP scope
• Attendee Experience API focuses on full-text search only

# 2. Event Management API - Added FR18 Topic Backlog Endpoints

File: docs/architecture/04-api-event-management.md

New Endpoints Added:

# Topic Backlog Management

1. GET /api/v1/topics/backlog

   • List topic backlog with heat map and staleness data
   • Supports sorting by staleness, usage_count, last_used, similarity
   • Returns TopicBacklogItem[] with analytics

2. POST /api/v1/topics/backlog

   • Add new topic to backlog
   • Automatic duplicate detection via ML similarity scoring
   • Returns 409 Conflict if similar topic exists (similarity > 0.8)

3. GET /api/v1/topics/backlog/{topicId}/similarity

   • ML-powered similarity analysis for topic
   • Configurable similarity threshold (default: 0.7)
   • Returns SimilarTopicMatch[] with recommended actions

4. GET /api/v1/topics/backlog/{topicId}/staleness

   • Get staleness metrics and recommended wait period
   • Analyzes historical patterns and partner influence
   • Returns TopicStalenessMetrics with recommendation

New Schemas Added:

• TopicBacklogItem - Complete topic metadata with heat map data
• CreateTopicBacklogRequest - Topic creation with similarity checking
• SimilarTopicMatch - ML similarity results with recommended action
• TopicStalenessMetrics - Comprehensive staleness analysis

Updated:

• Overview section now mentions “Topic backlog management with ML-powered similarity and staleness detection”
• API Design overview updated to include topic backlog endpoints

Rationale: FR18 requires smart topic backlog management with:

• Visual heat map showing usage frequency over time
• ML-powered similarity scoring for duplicate detection
• Staleness detection with recommended wait periods
• Partner influence metrics

Impact:

• 4 new endpoints supporting FR18 requirements
• 4 new schemas with comprehensive topic analytics
• Enables intelligent topic selection workflow for Epic 2

# 3. Partner Coordination API - Enhanced FR14 Notification Preferences

File: docs/architecture/04-api-partner-coordination.md

Schema Enhancements:

# NotificationPreferences (Completely Restructured)

Before:

NotificationPreferences:
  emailEnabled: boolean
  emailFrequency: enum
  realTimeEnabled: boolean
  notificationTypes:
    speakerInvitations: boolean
    eventUpdates: boolean
    ...

After:

NotificationPreferences:
  channels:
    email:
      enabled: boolean
      frequency: enum [immediate, daily_digest, weekly_digest]
    inApp:
      enabled: boolean
      soundEnabled: boolean
    push:
      enabled: boolean
      deviceTokens: string[]
    sms:
      enabled: boolean
      phoneNumber: string
      criticalOnly: boolean
  quietHours:
    enabled: boolean
    startTime: string (HH:MM)
    endTime: string (HH:MM)
    timezone: string (IANA)
    allowCritical: boolean
  notificationTypes:
    speakerInvitations: NotificationTypePreference
    eventUpdates: NotificationTypePreference
    ... (7 types total)

New Schema:

NotificationTypePreference:
  email: boolean
  inApp: boolean
  push: boolean
  sms: boolean

Key Improvements:

1. Multi-channel Support: Separate controls for email, in-app, push, SMS
2. Quiet Hours: Do-not-disturb settings with timezone support
3. Granular Control: Per-notification-type, per-channel preferences
4. Critical Notifications: Override quiet hours for critical alerts

Rationale: Enhanced FR14 requires:

• Granular notification preference controls
• Opt in/out per notification type
• Multiple channels (email, in-app, push, SMS)
• Frequency management and quiet hours settings

Impact:

• Existing preference endpoints remain unchanged
• Schema now supports all FR14 requirements
• Backward compatible (old clients can use simplified subset)

# 4. Partner Coordination API - Added FR7 Email Template Features

File: docs/architecture/04-api-partner-coordination.md

Schema Enhancements:

# EmailTemplate (Enhanced with Versioning and A/B Testing)

New Fields Added:

• version: integer - Auto-incremented version number
• isActive: boolean - Whether this version is currently active
• abTestConfig: object - A/B testing configuration
  • enabled: boolean
  • variantId: string (A, B, C, etc.)
  • weight: integer (0-100% recipient distribution)
  • metrics: object (sentCount, openRate, clickRate, conversionRate)
• previousVersionId: uuid - Reference to previous version
• createdBy: uuid - Audit trail
• updatedBy: uuid - Audit trail

New Endpoints Added:

1. GET /api/v1/notifications/templates/{templateId}/versions

   • Get complete version history for template
   • Returns array of all EmailTemplate versions

2. POST /api/v1/notifications/templates/{templateId}/rollback

   • Rollback template to specific previous version
   • Requires target version number and reason
   • Creates new version (doesn’t delete history)

3. POST /api/v1/notifications/templates/{templateId}/ab-test

   • Configure A/B test variants for template
   • Define variant weights and duration
   • Returns test ID and variant templates

Rationale: Enhanced FR7 requires:

• Email template management with variable substitution ✅ (already had)
• Multilingual support ✅ (already had)
• Version control with rollback capabilities ✅ (now added)
• A/B testing capabilities ✅ (now added)

Impact:

• 3 new endpoints for template management
• Complete version history and rollback support
• A/B testing framework for email optimization
• Metrics tracking for template performance

# 5. Event Management API - FR22 Role Management (No Changes Required)

File: docs/architecture/04-api-event-management.md

Verification Results:

✅ Already Complete - No changes required. Existing API already supports all FR22 requirements:

Existing Endpoints:

• GET /api/v1/users/{userId}/roles - Role history
• POST /api/v1/users/{userId}/roles - Promote user to role
• DELETE /api/v1/users/{userId}/roles/{role} - Demote user from role
• POST /api/v1/users/{userId}/role-changes/{changeId}/approve - Approve organizer demotion

Existing Schemas:

• UserRole enum (ORGANIZER, SPEAKER, PARTNER, ATTENDEE)
• RoleChange - Complete audit trail
• RoleChangeRequest - Approval workflow for organizer demotion

FR22 Requirements Met:

• ✅ Promote users to speaker or organizer roles
• ✅ Demote users with approval workflows for organizer demotions
• ✅ Enforce business rules (minimum 2 organizers per event)
• ✅ Maintain complete audit trails of all role changes

# 6. API Design Overview - Updated References

File: docs/architecture/04-api-design.md

Changes Made:

1. Event Management API Section:

   • Added topic backlog endpoint to key endpoints list
   • Added “Topic backlog management with heat maps and duplicate detection” to workflows
   • Updated use case description to include “topic backlog management”

2. Attendee Experience API Section:

   • Removed “personalized recommendations” from description
   • Removed “AI-powered” from endpoint description
   • Removed “Personalized recommendations” from workflows

Impact:

• Index document now accurately reflects all domain API capabilities
• Quick reference guides users to correct APIs for their needs
