# Submit encounter eligibility check (Availity)

GET https://api.joincandidhealth.com/api/eligibility/v2/availity

Candid is deprecating support for this endpoint. It is instead recommended to use [Candid's Stedi passthrough endpoint](https://docs.joincandidhealth.com/api-reference/pre-encounter/eligibility-checks/v-1/post).
For assistance with the transition, please reference the [Transitioning to Candid's New Eligibility Endpoint](https://support.joincandidhealth.com/hc/en-us/articles/34918552872980) document in the Candid Support Center.**Availity has transitioned their GET endpoint to a POST endpoint. Candid has updated their pass-through integration to enable backwards compatibility for the GET endpoint so that customers do not have to immediately update their integrations.****Candid recommends integrations with the [POST endpoint](https://docs.joincandidhealth.com/api-reference/eligibility/v-2/submit-eligibility-check-availity-post) to ensure the best possible integration experience. Given the transition, Availity’s documentation will be out of sync with this endpoint.**If you'd like access to this endpoint, please reach out to [support@joincandidhealth.com](mailto:support@joincandidhealth.com) with the subject line "Action: Activate Availity Eligibility API EndpointThis API is a wrapper around Availity's coverages API.
