BFF Architecture And API Aggregation

Use When

• Frontend depends on multiple backend services per screen
• Different clients (web, mobile, partner) need tailored payloads

Workflow

1. Define client-specific BFF boundary and ownership.
2. Design response contracts optimized for UI rendering.
3. Implement upstream call orchestration with timeouts and fallbacks.
4. Add partial-failure handling and graceful degradation.
5. Measure end-to-end latency and payload efficiency.
