Policies
Backoff Strategy
Use exponential backoff with jitter on 429/503 and honor Retry-After when present.
Sandbox vs production
Sandbox traffic is throttled lower than production; do not load-test production credentials.
HIPAA / PHI handling
All access to PHI requires BAA and security configuration agreed during onboarding.
