Availity API

Last reviewed: September 2026

Overview

Integuru provides production-ready HTTP API access to Availity. The actions listed on this page are currently supported by Integuru.

The five actions authenticate against Availity Essentials with your own provider login. Three read the Remittance Viewer (search_checks, search_claim_payments, download_payment_eop), one lists the organizations the login can act for (list_organizations), and one runs a real-time eligibility inquiry for a patient against a named payer (macias_v1_central_health_eligibility).

Does Availity have a public API?

Availity publishes APIs, but there is no self-serve developer path. A team building on Availity's eligibility, claims or prior authorization data must complete provider enrollment, sign payer-specific agreements for every payer it transacts with and meet Availity's trading partner requirements before receiving credentials. Integuru's Availity actions authenticate against Availity Essentials with the provider's own login.

What is live. Remittance first: search_checks and search_claim_payments page through payer checks, EFTs and claim-level payments by check date, payer, NPI, tax ID or claim number, using a Relay cursor (first for page size, after to continue). download_payment_eop returns the remittance EOP as a PDF for one check number. list_organizations returns the organizations your login can act for, which is the customer_id the remittance actions accept. macias_v1_central_health_eligibility runs a real-time eligibility inquiry for a patient by name, date of birth, member ID and service date; it resolves the payer live against your account's Availity payer directory and currently supports Central Health Medicare Plan, Anthem Blue Cross and CalViva Health.

What is not live. Claim submission, claim status, prior authorization submission and status, and patient balance lookups are not in the verified catalog. Availity shows those screens to the same login, so the Managed Service can build them against your organization; they are listed here only after they pass against live traffic.

Setup Notes

Configure Availity credentials in Integuru once. Integuru manages authentication and session handling for subsequent API calls.

Call list_organizations first if your login spans more than one organization; pass the result as customer_id on the remittance actions, or omit it to let the session's organization apply. Dates are YYYY-MM-DD. The eligibility action evaluates coverage as of service_date, not today, and returns an error rather than falling back when the requested payer is not in your payer directory.

Get started

Install the CLI and connect your Availity Essentials login:

npm install -g integuru

Or sign in at app.integuru.com, add Availity, and call the same 5 actions from the dashboard. For claim submission, prior authorization or another payer's eligibility flow, the Managed Service scopes and builds it against your organization.
