API reference

Base URL https://api.choicearrangementdeck.com/api/v1. Authenticate with OAuth 2.0 client credentials (POST /api/v1/oauth/token), then send Authorization: Bearer <token>. This reference follows the IDEON API: IDEON paths and snake_case field names, errors as {"errors":{...}}, Accept-Version v6 to v9, select and page/per_page. Coverage is ACA individual-market medical plans and Medicare Advantage only (Medicare Advantage and Part D plans with fuller benefits are in the v1 reference under /v1/medicare); groups, members and ICHRA calls are stateless (send the data in every request, nothing is stored). Differences and unsupported endpoints are listed in the description at the top of the reference and in docs/developer-api.md. Within a major version changes are backward compatible; breaking changes ship as a new version with at least 12 months' notice.
