Integration Design

Purpose

Design robust integration patterns for external APIs including adapters, error handling, and resilience.

Process

1. Analyze external API
2. Design adapter layer
3. Plan error handling
4. Implement resilience patterns
5. Define sync strategy

StudyAbroad-Specific Considerations

• University database API (rate-limited)
• OAuth providers (Google)
• Document scanning service
• Email service

Examples

Integration Pattern: University API

Adapter: UniversityApiAdapter
  - Transforms external format to internal
  - Handles rate limiting (100 req/min)
  - Implements circuit breaker
  - Caches responses (1 hour)

Sync Strategy:
  - Full sync: Daily at 2 AM
  - Incremental: Every 4 hours
  - On-demand: User triggers refresh
