Humana Rate Limits

Humana's developer portal does not publish numeric rate limits for its FHIR APIs. Limits are administered behind the scenes consistent with CMS Patient Access expectations and reasonable-use protections, scoped per registered application and per member token. Production apps that exceed fair-use thresholds are contacted directly. Sandbox endpoints are bound by similar reasonable-use ceilings without published numbers.

Humana Rate Limits is the machine-readable rate-limit profile for Humana on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring requests_per_second.

The profile also includes 5 backoff/retry policies defined.

Tagged areas include Rate Limiting, FHIR, Healthcare, and CMS.

Policies

SMART on FHIR Authorization
Production member data access requires SMART on FHIR / OAuth 2.0 with explicit member consent. Tokens are short-lived and refresh tokens are subject to revocation.
Application Attestation
Developer apps must attest to CMS privacy / data use practices before production access is granted.
Backoff Strategy
Implement exponential backoff and honor any Retry-After response header; pace requests conservatively given the absence of published numeric limits.
Sandbox vs Production
Test against the sandbox at sandbox-fhir.humana.com before promoting to fhir.humana.com. Production apps require completed registration.
Portal Migration
The developers.humana.com portal will be retired; FHIR products and consuming apps will migrate to a successor portal. Watch for migration guidance.
