Note

This entry refers to the [Legacy Real-Time Eligibility Check JSON](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-eligibility-legacy) endpoint. We now have a [redesigned version](https://www.stedi.com/changelog/introducing-our-redesigned-json-real-time-eligibility-check-api) of that endpoint.

We strongly recommend the [redesigned endpoint](https://www.stedi.com/docs/healthcare/api-reference/post-eligibility-check) for new implementations. Its request and response shapes are more intuitive for both developers and AI agents, which speeds up integration. We still fix bugs in the legacy endpoint, but it's no longer under active development.

You can now submit mock requests to the [Legacy Real-Time Eligibility Check JSON](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-eligibility-legacy) endpoint, and Stedi returns mock eligibility responses you can use for testing. To send a mock request, you need a Stedi API key for authentication, and you must set the `stedi-test` header to `true`.
