  update:
    x-apievangelist-provenance: Harvested verbatim from developer.availity.com on 2026-08-14; first-party Availity
      document.
    x-apievangelist-repo: https://github.com/api-evangelist/availity
    x-apievangelist-spec-format: Swagger 2.0 as published by Availity; not converted to OpenAPI 3.x by Availity.

- target: $.securityDefinitions.oauth2
  update:
    x-apievangelist-note: Operations in this document require the literal scope "hipaa", which is not defined in
      this scopes map. The scope vocabulary Availity actually grants at the token endpoint is the product/plan pair
      (e.g. "healthcare-hipaa-transactions healthcare-hipaa-transactions-demo"). Sending "hipaa" will not obtain
      a token. See scopes/availity-scopes.yml.
    x-apievangelist-token-ttl-seconds: 300
- target: $.info
  update:
    x-apievangelist-rate-limits: 'No rate-limit response headers and no Retry-After are published. Standard plan
      ceiling is 100,000 calls/day and 100 calls/second (AWS Payer List: 1,000,000/day, 100/second). Exhaustion
      returns a bare 429. See rate-limits/availity-rate-limits.yml.'
    x-apievangelist-idempotency: No idempotency key is published. Do not blind-retry an unsafe method; re-poll the
      transaction id instead.
- target: $.paths['/'].post
  update:
    x-apievangelist-async:
      pattern: 202-accepted-then-poll
      note: 202 Accepted is returned BOTH on submission and on a poll that is not yet complete. Treat 202 on a GET
        as "not finished, poll again", never as success.
