Availity provider portal and API transactions onboarding

Steps

1. Register for an Availity developer account at https://developer.availity.com and create an application to receive OAuth 2.0 client credentials.
2. Obtain an access token by posting to the Availity OAuth2 token endpoint (POST /v1/token) with your client_id, client_secret, and grant_type=client_credentials; the response includes access_token and expiration.
3. Subscribe to the API products relevant to your workflow (Coverages for eligibility, Claim Statuses, Service Reviews for prior auth) via the developer portal — Demo plan subscriptions are auto-approved for sandbox testing.
4. For HIPAA transaction enrollment (to submit X12 270/276/278 transactions), complete the Transaction Enrollment process in the portal, which links your application to your provider organization and trading partner agreements.
5. Make API calls using the access token in the Authorization: Bearer header; use the Availity Payer List API to look up payer IDs before submitting transactions.
6. Move from Demo to Production subscription by completing Availity's review and approval process, which includes attestation of HIPAA compliance and production-readiness.
