Must-Have Features for MVP
Metadata introspection of ERP (OData/RFC/IDoc/SOAP) to auto-generate schemas
Recipe-based endpoint composer with policy guardrails and approvals
In-line transformation DSL (JS/WASM) and reusable functions
Runtime rewire via feature flags and consumer-aware traffic routing
Contract testing, mock servers, and automatic SDK generation
Latency budgets, caching with persisted queries, circuit breakers
Schema diff alerts and deprecation workflows with safe rollback
⚠️ Potential Challenges
- Governance around who can change contracts
- ERP rate limits and long-running transactions
- Eventual consistency across composed resources
- Performance tuning of complex graph queries
Risk Level: Low
🎯 Keys to Success
- Create/modify endpoints in under 1 day without ERP code changes
- Zero client redeploys for backward-compatible changes
- API error rate under 0.2% and p95 latency within budget
- Developer NPS improvement of ≥20 points within a quarter
