Cvs Health Rate Limits
CVS Health does not publish public API rate-limit numbers. Patient-access FHIR endpoints enforce per-app and per-member soft caps consistent with CMS rule guidance; partner integrations are throttled per contract.

Backoff Strategy
Honor Retry-After when present; use exponential backoff with jitter on 429 / 503.
PHI handling
All access is patient-authorized via SMART-on-FHIR or partner agreement; tokens have short lifetimes and must be rotated.
Contract-scoped throughput
Partner integration TPS is set in the integration agreement, not on a public docs page.
