Eligibility Hub API

For software that connects directly, Eligibility Hub offers a documented REST API with an OpenAPI specification and a developer guide. It covers eligibility checks, medical and dental claims, predeterminations, authorization and appeal records, an acknowledgment and remittance event feed, and onboarding status. Each practice gets its own keys, with separate test and live modes.

Questions

Is there an API specification?

Yes. The API is documented with an OpenAPI specification and a developer guide.

Can we test without real patient data?

Yes. Each practice gets separate test and live modes, and test mode never sends real patient data to the clearinghouse.

Do we need the API to use Eligibility Hub?

No. Practices connect through the API or through the admin software we build for them.
