Contract-Defined Limits
Per-partner throughput and concurrency caps are issued by TIAA's API onboarding team and may differ between sandbox and production environments.
Backoff Strategy
Standard practice for TIAA's FDX-aligned endpoints is exponential backoff on 429/503 responses, honoring Retry-After when present.
